Description
Technical field
The present invention relates to electronic unit is carried out that bubble-free resin-sealed, scolding tin projection with precise shape forms, fill in the substrate hole or printing equipment, manufacturing installation and the manufacture method of the electronic unit of distribution etc.
Background technology
Original technology has been published in the following document.For example, as original encapsulation technology, well-known is that the integrated circuit that is formed on the workpiece is sealed (modularization).Its main flow is a conversion mould method, but as the method that adopts the plastic material of being made up of aqueous synthetic resin, and well-known have apportion design and a print process.Method and vacuum pressure reduction print process that atmosphere printing and deaeration are arranged concerning print process.What ceramic substrate was mainly adopted is vacuum pressure reduction print process.With regard to the plastic material substrate, part has adopted vacuum pressure reduction print process, and is enlarging gradually, but also has variety of issue and do not become main flow as yet.In addition, in the CSP of wafer level manufacturing engineering or its sealing, also used this method.From now on, the interior dressization along with integrated, the three dimensional stress or the substrate of electronic unit will require bubble-free encapsulating method with precise shape.
Concerning the scolding tin protrusion-shaped became, with respect to original replica method, print process was also gazed at recently.Make the high viscosity solder(ing) paste corresponding to narrow spacingization, how quantitatively the high hole version mask plate of aspect ratio bubble-freely to be filled is important techniques, has proposed various schemes.Use the atmosphere printing machine, the print head of printing machine has been introduced with open squeegee, sealed squeegee, has been pressed into the mode that type squeegee, sealing squeegee, the forced squeegee of roller print or fill.In addition, also have projection formation to make the plane stacked and formation perforation of photosensitive dry film, form projection, the method for stripping film with print process landfill solder(ing) paste, refluence with wafer.

Use the hole version, the principle that high viscosity resins flatly is printed as the shape with space is false with squeegee.Shown in Figure 15 (a), attached to the resin m on squeegee 60 and the workpiece 2, have up and down at interval at the peristome 103 of hole version 1, with respect to the mobile generation velocity gradient of squeegee 60, the resin m at rear is stretched, and is printed than the resin of the thin tens of μ m of specific thickness.This is the resin supply method that is not subjected to bond degree and gap affects.
Shown in Figure 15 (b), in the terminal of the peristome 103 of hole version 1, the resin m that is entered by squeegee 60 extruding is in the end of peristome 103, be plugged and squeegee 60 by the time pressurized opening wide, be printed than the resin of the thick tens of μ m of specific thickness.This is that the shape of the stuffing pressure of leading section of squeegee and mask plate and workpiece 2 irrelevant and keep constant method always.
The printing beginning portion of the slot part of the chip chamber in the peristome 103 of hole version 1 shown in Figure 15 and the not shown peristome that goes out 103 can not follow the stuffing pressure of squeegee 60, is filled or attenuation can not be printed and become the reason that produces bubble.Because of above-mentioned three essential factors, aqueous resin can not be printed as accurate shape, must not adopt the shape of mask or the useless action of squeegee 60 then, and sacrifices reliability the viscosity of resin is handled, but can not be from being solved in essence.This is that shape to Printing Department does not have influence that the resin supply method of powerful filling power is but arranged.
In BGA such as lamination type or CSP sealing, by wire bond, extension netted put into the high viscosity resins of high percentage filler etc., can not fully fill with the function of squeegee with to high-density.To this, printing and apply vacuum pressure reduction under vacuum though can expect filling effect to a certain degree, is not got rid of the mechanism of residual bubble, and bubble granular and scattering remains.Basically, before applying pressure reduction the resin filling cavity to squeeze out air be necessary condition.Concerning encapsulation as thin as a wafer, lead-in wire disconnects with blank part near the surface, does not produce pressure reduction, produces the dangerous high of bubble.In addition, the actual installation of 3 dimension laminations to high-density by wire bond, and is made flip-chip, because small gap also is required to obtain to fill, so have powerful filling function and can accurate method of printing be indispensable.Also have, in built-inization of substrate of electronic unit, the no bubble of aqueous resin is filled and the coating of uniform thickness is necessary.This be not subjected to viscous effects brute force fill method and do not have the bubble fill method.
Occasion in the perforation that various resins is filled into wafer substrate or laminated substrate needs powerful pressure, and because of the suction of squeegee or the viscosity of resin, resin gets out from perforation, and shrinks because of curing.Use various masks in order to cover these, critically adjust the position and fill and mended, but be formed with the hard plunger of convex, grind this and be accompanied by very big difficulty.This is that hole version, precision positions adjusting device and cleaning device all do not have, and directly fills on workpiece 2, and no bubble can be covered the contraction of recess and resin, makes attrition process reduce to the filling perforation method of irreducible minimum.
Be described in detail, on workpiece mask positioned, in the bottom anchor clamps that form plunger are positioned and print, form plunger (convex printing) on the two sides of workpiece, sclerosis is also ground.This occasion, print according to the diameter difference in the hole of different-diameter, and to the grinding of hardening of each hole diameter.Also have, for granular and large substrate, the pattern of mask and the pattern of workpiece are upheld because of the grinding of the extension of mask or workpiece and are made the position not overlap need to be divided into twice and print.Very important because of forming plunger with grinding, grind plunger and copper coating equably, need use a lot of devices to thickness with upholding to manage.In case being required does not have bubbleization, just becomes the printing under the vacuum, and mask is arranged, just become the device that possesses position adjustment, cleaning etc., it is the sort of large-scale and price is high to become complete set of equipments, and the low device of production efficiency.Need seek not have bubble, not use anchor clamps or mask to form plunger, can fill the hole in different apertures simultaneously, and make the filling perforation method that is processed as irreducible minimum.
For the formation of the projection of scolding tin, open in the flat 10-34878 communique TOHKEMY 2001-232758 number and spy and to have proposed the solder(ing) paste printing process.The disadvantage of these methods is, owing to be rotation and mask potting resin by roller, write down the mode of residual resin by scraper plate or blade on mask, filling power extremely a little less than.In the method, only half scope of roller 30 helps to fill, and second half hinders the filling of resin.For this is replenished, in the technology of TOHKEMY 2001-232758 communique, though carry out air pressurized, distance is elongated, and amount of resin also changes, and high viscosity resins reacts unequally.Be quite large-scale device as a whole, and be difficult in vacuum plant, adopt.
In addition, narrate with reference to Figure 16 (a) and Figure 16 (b), these modes are that hole version (mask) 1 and roller 30 are approaching, block resin m and fill.In hole version 1 or workpiece 2, fill the occasion in very big space, resin m only wind the roller 30 represented with arrow 30x or arrow 30y around circulation, almost irrelevant and have a very big defective concerning filling.
In the technology of patent application 2001-232765 communique, the difference that the roller rear portion retracts the pressurization of the power of resin m and resin m integral body is that the pressure of internal pressure uprises, and scraper plate is not blocked resin m squeeze out and very heavy back printing.Major part is helpless to fill even packing space diminishes, but is difficult to reach powerful filling owing to also working from the power that retracts resin m midway, thereby can not control the printing shape.
Te Kaiping 10-34878 communique also is,, is pulled the pressure transient between the roller 30 at posterior leaflet and rear portion and can not control the printing shape though have half effect relevant with filling power of roller concerning little space at roller 30 rear portions very weakly.In addition, print process with above-mentioned blade or scraper plate shape has on the substrate that forms with photoresist the destroyed and defective of peeling off of the direct words photoresist of printing, formation with further miniaturization utilizes the mask mode of mask hole version to reach the limit of, and changes to mode general and with photoresist formation pattern gradually.Requirement directly keeps powerful filling power on the workpiece that needs the space with various shape, to smooth or convex can both accurate printing the basic fundamental key element.
Patent application 2001-232758 communique is that by firm framework encirclement, replacing resin is very difficult thing around the roller.Needing to decompose this device cleans.Even the kind of scolding tin only, kind also becomes very many recently.In addition, this device need carry out resin-sealed and various filling perforation, only can replace resin and can whether grasp the key of practicability simply with a spot of solvent, must adopt the surplus next roller of part of contact pressure resin, squeegee is deviate from simply, the structure that can clean easily.
Also have, the manner is owing to sealed fully around the roller, even the boundary of mask and scraper plate also sucks air.In addition, Te Kaiping 10-34878 communique also is, formed with the whole bag of tricks such as photoresists on the substrate of perforation, fill solder(ing) paste, the air in the perforation is brought in the resin, and resin continues rotation around roller, the solder(ing) paste of saving that comprises a large amount of bubbles that is directly proportional with travel distance just is supplied to, also tail off even fill soldering tin amount, accurate projection can not be made, and also comprises bubble in inside.In addition, nearest solder ball is easy to the acidifying of improper ground by granular, to also producing very big problem in the dissolving of the scolding tin of stroke afterwards.
In addition, in the printing process of above-mentioned vacuum pressure reduction, in the printing engineering that plastic material m extrusion packing is advanced in the workpiece 2, because plastic material and workpiece 2 are bonded on the hole version 1 very doughtily, hole version 1 is left in the engineering of workpiece 2, and it is difficult cutting off this plastic material.Bonding like this plastic material m hangs down from this hole version 1 under the state that is bonded in hole version 1, also can cause the ruined problem of shape of sealing (encapsulation) in addition.
In more detail, shown in Figure 17 (a), in the occasion of implementing the porous printing method with the plastic material m of high viscositys such as resin, bonding plastic material on hole version 1 and workpiece (wiring board) 2, during from hole version 1 cut-out workpiece 2, the sealing of being made up of the plastic material m that forms sealing is stretched on every side.Like this, the end thickening of the sealing of forming by plastic material m, near the edge thinning it rises and falls and produce thickness.Have, the plastic material m that hangs down from hole version 1 perhaps owing to fall on the workpiece 2 always, implements this print process because of the recoil the cut off back side attached to hole version 1 at every turn again, and the cleaning of hole version 1 or workpiece 2 is obligato.In addition, also become the main cause of the deal change of the plastic material m that supplies with this printing.
In addition, shown in figure (b), have the sealing planarization that above-mentioned thickness rises and falls in order to make, attempted this is placed certain hour in atmosphere, viscosity reduces but harden midway at plastic material m, will cause that they flow out, the ruined problem of shape of sealing.As its countermeasure, alleviate plastic material m in downward (the キ ヤ PVC テ イ ダ ウ Application) mode of groove and flow, perhaps attempt waiting with distribution in advance the baffle plate of the dike shape that flows of making regulation plastic material m, just have the loaded down with trivial details problem of manufacturing engineering.
In the formation of scolding tin projection, the viscosity of solder(ing) paste is high, has proposed the scheme of various fill methods.But, become big by narrow spacing aspect ratio, be filled in the bonding force of solder(ing) paste on the workpiece 2 and diminish because of the difference of the bonding force of the area of sidewall, duplicate very unstable, the occasion of extracting from the hole version at resin, part residue and the occasion that is pulled out also has the occasion that is not pulled out, can reduce bonding countermeasure with the coating of shape, face rugosity and the separated type material in the hole of improving the hole version and compensate, but require not residual solder(ing) paste on the version of hole.This is the apportion design that is filled in the solder(ing) paste in the hole of hole version for the hole version.
In order to adapt to granular, be implemented on wafer substrate and the resin substrate and make mask with photoresist, be printed on atmosphere and fill scolding tin in the perforation, flow backwards the method for stripping photoresist, but the words of in blind hole, carrying out the atmosphere printing, air remains in inside, the loading deficiency.And the air that is directly proportional with travel distance the scolding tin in printing is also saved the quantity not sufficient of scolding tin.And owing to use squeegee, run out of because of viscosity, be printed as concavity, the soldering tin amount deficiency because of these reasons, and has the very low problem of projection precision.Also have, also become in the inner reason that produces bubble of projection.Hope obtains the method with bubble-free scolding tin resin quantitative filling.

And the manufacture method of electronic unit of the present invention is characterized in that, is included in the step that in the atmospheric pressure described workpiece is positioned.It is characterized in that, comprise the step that in a vacuum described workpiece is positioned.This occasion, powerful deaeration is carried out in circulation when also can be attached with remaining plastic material on described roller and contacting vacuum.Perhaps, it is characterized in that, be combined in step that in the atmospheric pressure described workpiece is positioned and the step that in a vacuum described workpiece is positioned continuously.
Adopt the printing equipment and the manufacture method thereof of electronic unit of the present invention, can reach following effect.Promptly, utilize whirler to make the roller rotation periphery supply plastic material of way roller simultaneously, the one side that makes roller rotation time that (being designated hereinafter simply as ' workpiece ') is installed along wiring board and surface moves this roller straight line, and plastic material is extruded attached to the periphery of roller the time between the roller and workpiece.On the other hand, in the process that moves along the one side of workpiece in roller rotation, squeegee is pushed the one side of workpiece.Under this state, the plastic material that squeezes between roller and the workpiece is rearward moved with respect to the moving direction of roller, but is had the angle that is suitable for filling and the squeegee regulation of length, and the resin between while roller and the squeegee is also sealed.
Therefore, plastic material rotation because of roller between roller and workpiece is admitted to resin with moving, utilize the filling power of squeegee and roller filling power make a concerted effort to apply powerful pressure the time, by direct extrusion packing to the substrate that mask is arranged with do not have on the substrate of mask, the adjustment of the angle by squeegee and the rotary speed of contact length and roller and translational speed makes filling power the most suitable according to purpose, the pressure of control squeegee front end, no matter be that can both not be subjected to shape and area effect smooth or convex print, at squeegee front end filling power is zero words, resin is flatly cut off, filling power is positive, just is printed as convex (with reference to Fig. 2).This is the invention that is filled into change period of the fundamental technology of printing on the parts with gap.
In addition, make the words that have plurality of gaps between squeegee and the roller, superfluous resin is circulation around roller, utilize this, for example, make it and vacuum combination, carry out in a vacuum attached to the roller surface circulation, supply with the plastic material (with reference to the symbol 235 of Figure 11) of complete deaeration, can be still less than original vacuum pressure differential method bubble.Make the rotation of squeegee pressure, roller and translational speed can drive separately and adjust respectively, just can be suitable on a large scale and suitable easily.
In addition, in order to make equipment miniaturization arrive the limit and to oversimplify, make this printing equipment adopt following structure to make that when squeegee was activated the reaction force of rotor rotation, the rotation of rotor was decelerated the machine deceleration and is communicated to back shaft, just can reach following effect.That is,, only adjust above-mentioned reaction force, in other words, only adjust the load that is applied on the roller, just can increase and decrease squeegee by the power that is pressed on the workpiece according to the viscosity of plastic material etc.In addition, the tooth bar interlock that the pinion that is combined in roller end portions and moving direction to workpiece one side that is laid in are extended owing to make the roller rotation by whirler, just can make equipment miniaturization arrive the limit and simplification.Control also just has only to be changeed, reverse, stops, simple to operate, and which type of processing is handled can both be realized at once.
Therefore, the occasion that disposes this device in a vacuum wanting from plastic material, to get rid of bubble fully, can dwindle the volume of for example closed chamber that forms this vacuum, do not use brakes such as air machine can not leak gas yet, can be used in vacuum and take out the miniaturizations such as vavuum pump of drawing closed chamber, the intensity of closed chamber is diminished and lightweight, can further make the production process cripetura and enhance productivity.Perhaps,, have the advantage that freely to adjust the amount of sending into of plastic material, how much can complicate but install adopting when making carriage that support roller rotates freely to structure that moving direction moves by the drive source that is located at the roller outside.
And, possess the inner casing of folding and unfolding whirler and around inner casing, the gap being set and the occasion of the shell of the tubular that disposes in above-mentioned rollers, in case make the rotor rotation of whirler, the shell and the inner casing of tubular rotate together.Their direction of rotation counter roller integral body above the version of hole mobile moving direction in preceding veer unanimity.
In addition, by between the inner casing of roller and cylindrical case the gap being set, the heat that whirler produces is prevented from being transmitted to the plastic material attached to the roller side face, and the viscosity that can suppress plastic material is subjected to Temperature Influence and changes.And, the inner casing of support roller and the shell of tubular, on the flange at two ends, be provided with through hole, be applied to as the Vacuum printing coating of a part of the present invention or the occasion of Vacuum printing machine, owing to vacuumize repeatedly, can cool off whirler energetically, so the viscosity of steady heat plastic material reliably.And, when forcing to cool off, make hollow being connected on the vavuum pump of back shaft at two ends.In addition, because roller contact with resin always, under with the state of squeegee grinding and become easily-consumed products, so cylindrical case must be easy replacement, for this reason, cylindrical case is effective.
And, adopt the printing equipment of electronic unit of the present invention, owing to make and have the one side that the hole version that makes the through-hole pattern that plastic material passes through overlaps at workpiece and also can play above-mentioned effect, so, strengthen because of the deaeration effect and the filling power of the rotation of roller, can obtain installing than original surface electronic units such as CSP, BGA substrate vacuum pressure reduction print process bubble still less and the sealing of the high precision of flatness.

Below, to printing equipment E1, be that example is illustrated based on Fig. 1 to Fig. 5 with the print head at the electronic unit that overlaps, makes an amount of plastic material of extrusion packing on one side 21 up the workpiece 2 with hole version 1.In addition, among the figure with the direction of arrow X, Y, Z indication corresponding respectively following axially, moving direction and short transverse.Self-explantory mechanical important documents such as bolt, nut, key, keyway and bearing are omitted its diagram or explanation.To the control machine of the action that is used to control printing equipment E1 and detect the sensor that moves/stop etc. and omit too.
The principle of the print head of printing equipment E1 at first is described.Fig. 1 represent periphery near the roller 3 of the one side 21 of workpiece 2, make roller 3 along the one side 21 of workpiece 2 to travel mechanism 4 that the direction of arrow Y indication moves, with respect to the moving direction of travel mechanism's 4 shifting rollers 3 make roller 3 forward the veer rotation rotating mechanism 5, be pressed into the squeegee 6 of the one side 21 of workpiece 2 near to or in contact with roller 3.
As travel mechanism 4, the carriage (not shown go out) that can be used in support roller 3 is gone up ball-type nut 40 is installed, on the other hand the mechanism by make feed screw 41 rotations that screw togather with ball-type nut 40 that roller 3 is moved with the drive sources such as motor that are configured in roller 3 outsides.As rotating mechanism 5, can be used in synchronous driving belt wheel 501 is installed on the output shaft of the whirler 50 that is configured in roller 3 outsides, on the back shaft 34 of roller 3, synchronous driving belt wheel 502 is set, and is situated between by being looped around the mechanism that synchrome conveying belt 503 on the synchronous driving belt wheel 501,502 passes to the revolving force of the output shaft of whirler 50 on roller 3.
The support body supports that squeegee 6 is not expressed among the figure and can be just passable along the rotation of the periphery of roller 3, for example, also can by based on the additonal pressure generation mechanism 7 of brakes such as cylinder moderately by on the one side 21 that is pressed in workpiece 2.Additonal pressure produces mechanism 7 near the slide hinge 70 that is located at the roller 3, is mounted to upright posture or inclination posture to rotate freely, and its brake bar 71 is situated between to be rotated by slide hinge 72 to be connected on the squeegee 6 freely.In addition, a pair of squeegee 6 one sides shown in Figure 1 are produced mechanism 7 by on the one side 21 that is pressed in workpiece 2 by additonal pressure, and the opposing party lifts from the one side 21 of workpiece 2.This is in order to be detained an amount of plastic material m at the downside that is positioned at respect to the squeegee 6 in the place ahead of the moving direction Y of roller 3, plastic material m follows the rotation of roller 3 to be drawn towards its downside gradually, and is positioned at squeegee 6 compressions with respect to the rear of the moving direction Y of roller 3.
In more detail,, be supplied to attached to the plastic material m on the periphery of roller 3 and move, be introduced into the downside of roller 3 gradually, between the one side 21 of workpiece 2 and roller 3, be compressed with roller 2 rotation as Fig. 2 (a) and (b).At this moment, the pressure that is applied on the plastic material m reaches peak value above the position P1 under the roller 3 slightly at plastic material m.Then, this pressure was set for before squeegee 6 arrives the contacting points position P2 of the one side 21 that touches workpiece 2 and is descended always, can also keep required pressure at contacting points position P2.Like this, (for example carrying out workpiece 2, printed substrate or wafer board) perforation or the occasion of the landfill of through hole, owing to can put aside the pressure of appropriateness among the plastic material m in imbedding perforation or through hole, so, as shown in the figure, after squeegee 6 passed through, plastic material m swelled and becomes convex from perforation or through hole.
Perhaps, as Fig. 2 (c) and (d), be supplied to attached to the plastic material m on the periphery of roller 3 and between the one side 21 of the workpiece of having stated 2 and roller 3, be compressed.And, be applied to pressure on the plastic material m set for plastic material m surpass slightly roller 3 under position P3 reach peak value, then, this pressure all is zero arrive contacting points position P4 always.Like this, owing to do not have residual compression at the plastic material m in the place that falls in of the one side 21 that is filled in workpiece 2, so as shown in the figure, even after squeegee 6 passes through, plastic material m also remains smooth shape.In order to be suitable for various purposes, preferably can independently adjust the rotation of roller 3, mobile and above-mentioned pressure.Below be described in detail the preferred forms that is used for the above principle of specific implementation.
Fig. 3 is the front view of printing equipment E1.Fig. 4 (a) is the side view of printing equipment E1, (b) is the sectional view of Fig. 3 along the A-A line.Fig. 5 roughly represents the formation of the major part of printing equipment E1.As shown in these figures, printing equipment E1 possesses: at the wiring board that is positioned with flat-hand position and near the both sides of workpiece 2 that surperficial installation portion by it is formed (following be designated as simply ' wiring board 2 '), axially the two ends 31 of X are supported respectively and make the roller 3 of periphery 32 near the one side 21 of wiring board 2 by hole version 1; Make roller 3 along the one side 21 of wiring board 2 to travel mechanism 4 that arrow Y direction moves; In the process that travel mechanism 4 moves roller 3, make the rotating mechanism 5 of roller 3 rotations; Near roller 3 supported can be along the squeegee 6 of periphery 32 rotations of roller 3; Utilize reaction force that rotating mechanism 5 makes roller 3 rotating moment with squeegee 6 by be pressed in the overlapping hole version 1 of the one side 21 of wiring board 2 on additonal pressure produce mechanism 7.
In case rotor 52 as above rotates like that, follow in this pinion 10 with roller 3 rotations.The rotating reactive force of roller 3 and pinion 10 is delivered to additonal pressure and produces mechanism 7, and additonal pressure produces mechanism 7 by squeegee 6 being pressed into the equilibrium of confining force on the hole version 1.Its principle will be narrated in the back.Pinion 10 rotation, roller 3 is just whole to move (below be designated as ' toward moving ' or " returning ") along the right side or the left side of moving direction Y in figure.Simultaneously, roller 3 is with respect to himself past direction of moving or returning, the direction of changeing forward rotation.
Just, roller 3 is in clockwise direction rotation in Fig. 4 when moving, when returning to counterclockwise rotating.Like this, the speed (circular velocity) of the periphery 32 of the roller 3 of ' preceding commentaries on classics ' is just roughly determined by the ratio of the diameter of the periphery 32 of the spacing of pinion 10 circle and roller 3.In illustrated embodiment, the speed of roller 3 is configured to roller 3 about 1.2~1.5 times to translational speed that arrow Y direction moves.
Rotating mechanism 5 possesses: the axial X along roller 3 extends, run through above-mentioned pinion 10 respectively and make the outstanding a pair of back shaft 34 in outside of each front end 33 way roller 3; The moment that will produce on the rotor 52 of whirler 50 is delivered to the reductor 8 of the back shaft 34 on (Fig. 3 right side) on one side; The a pair of attaching parts 9 that radially extend out near way roller 3 each front end 33 of a pair of back shaft 34.A pair of attaching parts 9 support the two ends with the squeegee support bar 95 of the central authorities of bolt 94 support squeegees 6 respectively, and squeegee 6 can be that fulcrum shakes slightly with bolt 94.In addition, each back shaft 34 can rotate freely with respect to roller 3 and each pinion 10.
Support a pair of support chip 35 respectively near each front end 33 of a pair of back shaft 34.A pair of support chip 35 is separately fixed on the pair of straight action-oriented bearing 36.And pair of straight action-oriented bearing 36 cooperates with the pair of guide rails 37 of extending to moving direction Y sliding freely.These parts are formed in the moving direction Y carriage 38 of support roller 3 sliding freely, make pinion 10 not break away from tooth bar 11, play the effect that direct pair roller 3 leads.
The additonal pressure generation mechanism 7 moderately rotation of pair roller 3 brakes, and in other words, it installs the strap brake 17 that pair roller 3 is given and loaded a side of a pair of support chip 35.Reductor 8 and strap brake 17 be owing to being that self-explantory technology is omitted its detailed diagram, only additonal pressure produced the principle that mechanism 7 is subjected to the reaction force of above-mentioned rotation and describe.The reductor 8 of the following stated roughly is made of with the box that cogs a plurality of planetary gears, the folding and unfolding that directly are connected sun gear on the rotor 52, be configured in around this sun gear.
That is, in case start whirler 52, rotor 52 rotations, this rotation just are decelerated machine 8 decelerations and pass to roller 3.Like this, in the right handed process of roller 3 in Fig. 4, this reaction force is situated between and is delivered to (Fig. 3 right side) back shaft 34 on one side by above-mentioned planetary gear, produces anticlockwise moment at this back shaft 34.As a result, the squeegee of in Fig. 4 (b), representing 6 with solid line just be pressed against with the overlapping hole version 1 of the one side 21 of wiring board 2 on.Perhaps, in case make the counter clockwise direction rotation of roller 3 in Fig. 4,, on back shaft 34 on one side, produce anticlockwise moment opposite when just changeing with rotor 52 as the reaction force of the rotation of roller 3.As a result, squeegee 6 turns clockwise with attaching parts 9.And squeegee 6 is run into hole version 1 and is staticly got off in arriving figure during with the position on the represented right side of imaginary line.
This whirler 50 repeats just to change at every turn/and when reversing, squeegee 6 repeats above spinning movement.In addition, additonal pressure produces mechanism's 7 pair rollers 3 and applies load, in other words, the rotation of the frictional force pair roller 3 that obtains by a certain side who fastens the two ends 31 of roller 3 with strap brake 17 applies resistance, increase the reaction force of whirler 50 energetically, just can adjust squeegee 6 and push power (being designated hereinafter simply as ' additonal pressure ') on the one side 21 of wiring board 2 according to hope.
Also have, the action of above squeegee 6 only is conceived to attaching parts 9 and narrates, in fact, because squeegee 6 is the shape of the length of total length more than 30~90cm of axial X, pressure to be adjusted to practical intensity, just must apply impartial pressure at the two ends of squeegee support bar 95 so that do not make squeegee 6 produce crooked or twist and warping.To this, preferred mechanical ground connects a pair of attaching parts 9.
For example, a pair of sector gear 91 is separately fixed on a pair of support chip 35 of carriage 38, to install freely with respect to the suitable local rotation of each attaching parts 9 with the planetary gear 92 of each sector gear 91 interlock, additional these a pair of planetary gear 92 usefulness connecting axles 93 be coupled together the interlinked mechanism that forms.Like this, the power that attaching parts 9 are on one side rotated around a back shaft 34 is transformed into by each gear 91,92 of attaching parts 9 sides and makes connecting axle 93 rotating moment, and this moment is transformed into the power of another attaching parts 9 around another back shaft 34 rotations that makes by each gear 91,92 of another attaching parts 9 sides.
In addition, illustrated is the example that 1 whirler 50 is installed in a roller 3, but 2 reductors 8 also can in a roller 3,2 whirlers being installed and being connected with the rotor 52 of each whirler, a pair of back shaft 34 of drive.This occasion, 2 whirlers 50 are owing to being used in the drive circuit same period that drives each whirler, so do not need above-mentioned interlinked mechanism.In addition, also can be guided out output, each reductor 8 is connected respectively to the two ends of rotor 52, a pair of back shaft 34 is connected respectively on these two reductors from the two ends of the rotor 52 of whirler 50.
In addition, as mentioned above, be that ball-type nut 40 is installed on the carriage 38, on the other hand in travel mechanism 4, make the occasion of the device of feed screw 41 rotations that screw togather with ball-type nut 40 with the drive sources such as motor of the outside that is configured in roller 3, can omit above-mentioned pinion 10 and tooth bar 11.In addition, hole version 1 is because key element not necessarily in the formation of printing equipment E1 and when using, so also can omit.
Secondly, based on Fig. 6 to Fig. 9 the manufacturing installation E2 of the electronic unit that has been assembled into above-mentioned printing equipment E1 (print head) is described.In addition, the travel mechanism 4 of above-mentioned printing equipment E1 is not limited to be installed in the structure of the whirler 50 in the roller 3, also can be that the ball-type nut etc. that is located at the drive source rotation of roller 3 outsides by utilization as previously mentioned moves roller 3.Fig. 6 (a) is the front view of manufacturing installation E2, and Fig. 7 is the front view of its major part.Fig. 8 and Fig. 9 are side view and the vertical views of each manufacturing installation E2.As shown in these figures, manufacturing installation E2 possesses: the top seal chamber 13 of folding and unfolding printing equipment E1 and hole version 1; The lower seal chamber 14 of folding and unfolding calibration console 12; Pressure reduction described later produces mechanism 15.
Pressure reduction produces mechanism 15 and makes top seal chamber 13 and lower seal chamber 14 states spaced apart from each other to utilize hole described later version 1, produces pressure reduction between top seal chamber 13 and lower seal chamber 14.For example, pressure reduction produces mechanism 15 and possesses: 1 vavuum pump 151 that both are connected with top seal chamber 13 and lower seal chamber 14; 2 vent valves 152,153 that are connected with lower seal chamber 14 with top seal chamber 13 respectively.And, shown in the piping diagram of Fig. 6 (b), between top seal chamber 13 and lower seal chamber 14 and vavuum pump 151, be provided with vent valve 152 and stop valve 155 in top seal chamber 13, be connected with vent valve 153 and stop valve 154 in lower seal chamber 14, by making up the operation of these valves, can be in the top seal chamber 13 and/or lower seal chamber 14 freely produce vacuum, can carry out the cut-out and the distribution of plastic material.
Secondly, the manufacture method of extrusion packing on the wiring board 2 that is positioned on the above-mentioned calibration console 12 having been advanced the electronic unit of an amount of plastic material describes.In addition, concerning with the manageable plastic material of this method, contain the aqueous resins such as epoxy resin of having sneaked into filler (sealing with) at least, epoxy resin sneaked into non-conductive adhesive (filling perforation with), solder(ing) paste (projection form with) and the polyimide resin/aqueous photoresist (the workpiece insulation is used) of fillers such as copper or silicon gel as bonding agent at the containing ratio of copper or silver in the conducting resinl/epoxy resin 80% or more.
At first, as Figure 10 and shown in Figure 11, on calibration console 12 wiring board 2 is positioned, the location of wiring board 2 is to be undertaken by being located at the pilot pin of not expressing among the figure on the calibration console 12.Under this state, the atmosphere that wiring board 2 is placed is that atmospheric pressure or vacuum all do not have special relationship.In addition, hole version 1 is overlapped with wiring board 2.The place of the one side 21 of wiring board 2 with tilings in advance such as films on the occasion of which floor (coverings) do not need hole version 1, but following corresponding with have run through simultaneously 101 and the example of the hole version of the through-hole pattern (peristome) 103 of another side 102 describe.
Then, as Fig. 9 is represented, allow roller 3 near hole version 1, wait for.Under this state, shown in Figure 11 (a), the periphery 32 of pair roller 3 or the one side of hole version 1 101 are supplied with plastic material m.Then, make the periphery 32 of roller 3 move closer to the one side 101 of hole version 1, make roller 3 along the one side 101 of hole version 1 toward moving the time, the direction rotation that roller 3 is changeed by whirler 50 before the moving direction Y that moves with respect to roller 3.Like this, just be pressed into toward between the moving roller 3 and hole version 1 attached to the plastic material m on the periphery 32 of roller 3.
In this process, be installed in the heat that the whirlers 50 in the roller 3 produce and be transmitted to attached to the plastic material m on the periphery 32 of roller 3, the viscosity that has a plastic material m is subjected to Temperature Influence and the shortcoming that changes.To this, shown in Figure 12 (a), also roller 3 can be made the inner casing 53 of the rotor 52 (omitting among this figure) that possesses folding and unfolding whirler 50 and around inner casing 53, the space 54 of about 2mm is set and the dual structure of the cylindrical case 55 that disposes.Like this, the heat that produces of whirler is transmitted to plastic material m via the periphery 32 of roller 3 and just is prevented from.In addition, in case make rotor 52 rotation of whirler 50, cylindrical case 55 just and inner casing 53 rotate together.This direction of rotation is the preceding veer with respect to integral body mobile moving direction above hole version 1 of roller 3.
And, also can adopt the structure of utilizing vavuum pump 151 air to be directed to space 54.This occasion, shown in Figure 12 (b), a plurality of passages 57 that form by space 54 in two ends 31 of roller 3, simultaneously, respectively hollow shaft is applied to a pair of back shaft 34 of roller 3, the endoporus 58 of these hollow shafts of process makes space 54 be connected with the vavuum pump of having stated 151.In case start vavuum pump 151, air just is directed to the inside of roller 3 from a plurality of passages 57, and this air is discharged to outside the roller 3 by vavuum pump 151.Like this, owing to can make the cooling of roller 3 and whirler energetically, so the viscosity of steady heat plastic material m positively.In addition, be preferably in when roller 3 is rotated, disconnection is supplied to the electric power of whirler 50 so that whirler 50 does not discharge unnecessary heat fully.
In addition, also can be used as at the lining (cladding material) that rubber system is set on the periphery 32 of roller 3 being pressed into well between roller 3 and the hole version 1, promote the bonding of plastic material m and roller 3 attached to the plastic material m on the periphery 32 of roller 3.In addition, because its wearing and tearing of rubber than very fast, so when changing this lining, only take out cylindrical case 55 such viewpoints and it seems from roller 3, are preferably made roller 3 above-mentioned the sort of dual structure.
Then, in roller 3 rotation by the process above the hole version 1 in, squeegee 6 is pressed against on the one side 101 of hole version 1 because of whirler 50 makes the reaction force of roller 3 rotating moment.For this reason, run to the rear just by 6 regulations of squeegee with respect to roller 3 toward moving direction as above being squeezed into like that toward moving roller 3 and the plastic material m between the hole version 1.Therefore, when between moving roller 3 and hole version 1, moderately pressurizeing, be supplied in the through-hole pattern 103 (forced feed).Like this, plastic material m just is extruded the one side 21 that is filled into wiring board 2 securely.As above such, the pressurized degree of plastic material m can be according to viscosity of plastic material m etc., and required value is set in the setting/adjustment of the rotary speed of the angle of the adjustment by above-mentioned pressure and the translational speed of squeegee 6, squeegee 6, the contact length of resin and roller 3 for.
In addition, in the occasion of omitting hole version 1, also can make the directly one sides 21 of contact wiring boards 2 of squeegee 6, at above-mentioned pressing plate or open the opening of very big printing zone on by press box, the resin on the not residual substrate plays the effect of handing-over.In addition, squeegee 6 also can make the sort of laterally zygomorphic shape shown in Figure 11 make with roller 3 toward moving or return and have nothing to do, can reach effect of uniform, but also can make the shape of two edge parts (top and the bottom in the drawings) asymmetric.This occasion toward moving or when returning, toward moving side, is used for setting the angle and the contact length of squeegee 6 by extrusion packing plastic material m at roller 3, is returning side, decides angle and length by what plastic material m surface is made smooth or convex.
Secondly, other manufacture methods to electronic unit describe.At first, as shown in figure 13, in base 230 with calibration console 12 directly over corresponding position framework 18 is set, on framework 18, hole version 1 is positioned with flat-hand position.On the other hand, wiring board 2 is positioned with flat-hand position on calibration console 12 with above-mentioned main points.By suitably this wiring board 2 being carried out Height Adjustment, make the another side 102 of the one side 21 of wiring board 2 near hole version 1.
Then, use method, utilize vavuum pump 151 to make top seal chamber 13 and lower seal chamber 14 be in vacuum state simultaneously as embodiment 3 narrations.In this process, can discharge (deaeration) under atmospheric pressure potential bubble fully to plastic material m.By through-hole pattern 103, give wiring board 2 with plastic material m extrusion packing with plastic material m forced feed hole version 1.And, make above-mentioned pressure reduction generation mechanism's 15 startups and between top seal chamber 13 that utilizes hole version 1 to separate and lower seal chamber 14, produce pressure reduction.
Then, be closed in the stop valve 155 shown in the piping diagram of Fig. 6 (b), open vent valve 152, the pressure of top seal chamber 13 rises.Like this, plastic material m is squeezed out downwards from the through-hole pattern 103 of hole version 1.And, calibration console 12 is descended a little, as shown in figure 13, plastic material m does not just remain on the through-hole pattern 103, copies to well on the wiring board 2.Then, make top seal chamber 13 and lower seal chamber 14 return atmospheric pressure, open lid 233 as shown in Figure 8, and open framework 18 and hole version 1, take out wiring board 2 from manufacturing installation E2, a series of manufacturing engineering just is through with.
Embodiment 5
Secondly, other manufacture methods to electronic unit describe.As shown in figure 14, on framework 18, hole version 1 is positioned, about the point that on calibration console 12, wiring board 2 is positioned identical with embodiment 4.And, by suitably wiring board 2 being carried out Height Adjustment, make the another side 102 of the one side 21 of wiring board 2 near hole version 1, utilize vavuum pump 151 to make top seal chamber 13 and lower seal chamber 14 be in vacuum state simultaneously, this puts also identical with embodiment 4 to wiring board 2 with plastic material m extrusion packing.
Then, separate hole version 1 and produce pressure reduction.Close the stop valve 154 shown in the piping diagram of Fig. 6 (b), open vent valve 153 slightly and since lower seal chamber 14 in press liter, the air pressure of another side 102 sides of hole version 1 is higher than one side 101 sides.Like this, because the little air of lower seal chamber 14 between the surrounding edge of plastic material m and through-hole pattern 103 is flown away upward, so plastic material m is cut off well from the surrounding edge of through-hole pattern 103.Be prevented from entering occasion between hole version 1 and the wiring board 2 at rigidity height, the air of hole version 1,, wiring board 2 left to the below of hole version 1, make the gap between wiring board 2 and the hole version 1 broaden also passable by the height of calibration console 12 is adjusted.
In addition, embodiment described top seal chambers 13 4,5 and lower seal chamber 14 not necessarily need in a vacuum, the air pressure of one side 101 sides of hole version 1, or at least one side of the air pressure of another side 102 sides is that atmospheric pressure is also passable.In addition, plastic material m is also passable for the synthetic resin that wiring board 2 is carried out insulated enclosure.Perhaps, plastic material m also can for the solder(ing) paste that forms the scolding tin projection.
The present invention can be applied to the electronic unit installed at workpiece surface resin-sealed, in the formation of the scolding tin projection of workpiece, the various manufacturing engineerings of the filling perforation of wiring board, the resinous coat of wiring board, field of display etc.
