Description

A kind of fast molded technique of Multilayer Flexible Board
Technical field
The present invention relates to printed circuit board (PCB) processing technique field, the fast molded technique of more particularly to a kind of Multilayer Flexible Board.
Background technology
The general Making programme of the making of Multilayer Flexible Board is:Sawing sheet → circuit making → pure glued membrane, flex plate para-position pressure Conjunction → rear operation, wherein, bonding processes must effectively remove the bubble of flex plate interlayer, for the performance impact of Multilayer Flexible Board Particularly critical, conventional pressing technology includes fast pressure and traditional vacuum pressure transmission at present.Traditional vacuum pressure transmission can be provided takes out true Altitude, can be prevented effectively from the generation of bubble in bonding processes, but the High Temperature High Pressure of traditional vacuum pressure transmission is easily caused flexibility Plate harmomegathus changes greatly, and time-consuming, cumbersome, not universal enough in printed circuit board industry application, by contrast, presses with which soon Simple to operate, the quick and low advantage of environmental requirement has more industrial application prospect.
Fast pressure flow process is specially:Pure glued membrane sawing sheet → brill location hole → paste pure glued membrane → pure glued membrane precompressed → flex plate in advance is pre- Para-position → Multilayer Flexible Board is pressed soon.Carry out by existing fast compression technology, be easily caused fast moulding film and flex plate para-position pressing During, in plate, gas effectively cannot be discharged, and form bubble.The presence of bubble, not only largely effects on product appearance, follow-up easy Forming layering plate bursting causes to scrap;If carrying out catching up with bubble to do over again to flex plate, Multilayer Flexible Board is pressed through multiple high temp, is held It is easily caused flex plate harmomegathus and becomes big and inconsistent, cause flex plate interlayer alignment precision to decline, follow-up drilling hole partially, and is made accordingly Into scrappage virtual height, making the risk and cost of enterprise is increased.
The content of the invention
The present invention thoroughly cannot be removed for the bubble that existing fast pressure technology is present, serious restriction Multilayer Flexible Board pressing product The problem of matter and scrappage virtual height, forms a kind of fast molded technique of Multilayer Flexible Board, with bubble removal effect is good, operation just The characteristics of prompt, with low cost and wide versatility.
Present disclosure is:
A kind of fast molded technique of Multilayer Flexible Board, comprises the following steps:
The first step, sawing sheet process, carry out flex plate, pure glued membrane according to process and cut;
Second step, Drilling operation, select the non-forming region in flex plate figure, are spaced in flex plate according to certain Carrying out catching up with pore to position, and Drilling operation being carried out in the position location for catching up with pore, pore is caught up with formation;
3rd step, rubberizing film pre-treatment, the flex plate for completing second step Drilling operation enter row line make, AOI detection, Brown makes, and completes pad pasting pre-treatment;
4th step, single layer flexible plate glued membrane are molded soon, and the 3rd step is completed to divide above the flex plate of pad pasting pre-treatment Glued membrane is not sticked in advance, modeling is crossed by laminator, flatten rapidly the glued membrane being attached on flex plate in advance after crossing modeling and complete single layer flexible plate Glued membrane it is molded soon, its concrete steps can three steps below atmosphere:
Step one, glued membrane are pasted in advance, are prepared fixed backing plate, first flex plate are inserted on backing plate, glued membrane release paper of tearing, protect Outwardly, glued membrane face using non-dust cloth is tentatively caught up with gas after being inserted in glued membrane towards flex plate to film, makes glued membrane face with flexible plate face After being fully contacted, reuse electric cautery and its technique edges is suitably fixed, complete glued membrane and paste in advance;
Step 2, modeling precompressed excessively:The flex plate of pre- rubberizing film is clamped up and down using special modeling accessory plate of crossing, opened modeling Machine, it is 100-150 DEG C to adjust temperature, and pressure reel speed 0.5-1.0m/min, pressure are certain, will first cross after mould plate one end compresses and is put into Machine carried out modeling, until imposite is crossed modeling and completed;
Step 3, glued membrane are pressed soon, and the single layer flexible plate to completing to mould precompressed is carried out rapidly in the state of heating pressurization It is fast molded, obtain final fast molded single layer flexible plate.
5th step, Multilayer Flexible Board are molded soon, it is the 4th step glued membrane fast it is molded after single layer flexible plate according to certain Level carry out pre- para-position, carry out high-temperature pressurizing and cross modeling by crossing mould plate and clamping, cross the monolayer of rapid compression different levels after moulding Flex plate, the glued membrane for completing Multilayer Flexible Board are molded soon.Its concrete steps can be divided into following three step:
The pre- para-position of step one, Multilayer Flexible Board, the protecting film of the single layer flexible plate surface for completing to mould precompressed is torn off, point Not successively be not inserted in fixed backing plate according to level, using non-dust cloth carry out it is secondary catch up with gas, after being fully contacted glued membrane face, ironed using electricity Ferrum is suitably fixed to its technique edges, completes pre- para-position;
Flex plate is clamped using special mould plate of crossing, opens laminator so as to temperature by step 2, Multilayer Flexible Board precompressed 100-150 DEG C is reached, modeling speed 0.5-1.0m/min is crossed, pressure is certain, and machine is put into after first compress one end carried out modeling, directly Modeling is crossed to imposite to complete;
Step 3, Multilayer Flexible Board are molded soon, and the Multilayer Flexible Board to completing precompressed is entered in the state of heating pressurization Row is rapid fast molded, obtains final fast molded Multilayer Flexible Board.
Preferably, the quantity for catching up with pore described in the 3rd step Drilling operation increases according in 30mm × 30mm~50mm × 50mm Plus one hole be arranged on the non-forming region of flex plate.Setting can not be overstocked, and crossing secret meeting increases difficulty of processing, can also increase multilamellar and scratch Property plate laminating after hidden danger of quality;Can not dredge excessively, dredge excessively the effect that can have a strong impact on removal of bubbles.
The invention has the beneficial effects as follows:
Firstth, bubble removal effect is good, catches up with stomatal limiting value bubble to arrange by increasing in the non-forming region of single layer flexible plate Go out passage, bubble removing is gone with molded soon by substep aerofluxuss pre-molding, effectively reduction bubble is between Multilayer Flexible Board Residual;
Secondth, easy to operate, each operation is normal process steps, and process operations are simple, is ensureing the same of bubble removal effect The step of Shi Youxiao simplifies operation;
3rd, it is with low cost, equipment and Environmental costs, operation side are effectively reduced without the need for special operational environment and Special Equipment Just cost of labor is effectively reduced, the use of material is the effectively save material cost of conventional material;
4th.Versatility is wide, for the number of plies of the Multilayer Flexible Board for needing processing.Size etc. is suitable for institute without limiting The popularization for having Multilayer Flexible Board makes.
