Description
Technical field
The present invention relates to PCB Graphic transitions, particularly a kind of outer film PIN follows closely the method for contraposition.
Background technology
The mode of operation of manual alignment is generally adopted in PCB manufacturing ectomesoderm Graphic transitions operation, personnel needed for in-process are more and alignment method is relatively complicated, often expose once, all will re-start film aligning, add the fussy degree of operation, production efficiency is low.
Summary of the invention
For overcoming the shortcomings and deficiencies of above-mentioned prior art, the invention provides a kind of method that outer film PIN simple to operate follows closely contraposition.
The technical solution adopted in the present invention is:
Outer film PIN follows closely a method for contraposition, and the described outer film comprises first film (A) and second film (B), comprises the following steps:
(1) make on first film 4 PIN holes, some butterflies and some target holes, outer film B makes with the butterfly on outer film A and the corresponding some butterflies overlapped in target hole with target hole; Described butterfly be the circular film region that fan-shaped photic zone and shading region alternately occur.
(2) by two outer films according to butterfly and target hole carry out coincidences aligning after, be fixed together with double faced adhesive tape;
(3) with a press strip and the outer film while be fixed together, described press strip is bonded between the two outer layers film, is then removed by the double faced adhesive tape described in step (2);
(4) by first-class for the nail of 4 on first film PIN nail, then be fixed with one side glue;
(5) finally step (4) being completed the two-layer film after integration is placed on exposure machine table top, press strip and first film is bonded on exposure machine table top.
Preferably, described butterfly (C) and target hole (D) are all located at the position outside the form wire of the film.
Preferably, the thickness of described press strip (F) is consistent with production plate.
Preferred further, the width 20 ~ 25mm of described press strip (F), length is than the length of side 10 ~ 15mm of the place film, and press strip is placed from form wire 15 ~ 20mm.
It is 3.15-3.18mm that described PIN follows closely width, is highly 1.2-1.5mm.
Using more intensive for circuit in two outer films one as the first film A.
Outer film PIN of the present invention follows closely the method for contraposition, on the basis of original contraposition by hand, by increasing, be bonded at the press strip between the two outer layers film, the outer film in the two sides of Graphic transitions circuit integrated, is then directly fixed on exposure machine table top, PIN nail is relied on to position product, as long as product directly to be put PIN nail, just directly can expose, operate comparatively simple.Additionally by butterfly and aspect, some target holes two carry out film aligning, simple to operate, precision is high.

Fig. 2 is the schematic diagram of second film of the present invention;
Fig. 3 is the schematic diagram after the present invention first film and second film complete integration.
Embodiment
Understand technology contents of the present invention for convenience of those skilled in the art, below in conjunction with embodiment, the present invention is described in further detail.
Outer film PIN follows closely a method for contraposition, and the described outer film comprises the first film A and the second film B, and circuit is wherein than of comparatively dense as the first film A, and concrete operations comprise step:
(1) on first film, make 4 PIN hole E, some butterflies C and some target hole D, the second film B makes some butterflies the C that overlap corresponding to butterfly the C on outer film A and target hole D and target hole D; Described butterfly C and target hole D is all located at the position outside the form wire of the film.
(2), after two outer films being carried out coincidence aligning according to butterfly C and target hole D, be fixed together with double faced adhesive tape;
(3) with a press strip F and the outer film while be fixed together, described press strip is bonded between the two outer layers film, is then removed by the double faced adhesive tape described in step (2); The thickness of described press strip F is consistent with production plate.Width 20 ~ the 25mm of described press strip F, length is placed from form wire 15 ~ 20mm than the length of side 10 ~ 15mm of the place film, press strip F.
(4) by first-class for 4 nail E on the first film A PIN nail, then be fixed with one side glue; The boring aperture in PIN hole is generally 3.2mm, and finished product aperture is generally 3.1mm, and plating back aperture will diminish, so when selection PIN follows closely width, range set is 3.15-3.18mm; What the height (i.e. the thickness of the PIN head of a nail) of PIN nail was conventional is the thickness of 1.2-1.5mm, if blocked up words easily produce the thin bad phenomenon of ill-exposed line, gets over Bao Yuehao in the choice, but is not durable lower than the thickness of 1.2mm and very easily fractures.Best selection is 1.2mm, if PIN follows closely periphery when not having a circuit certainly, the thickness selecting 1.5mm is also manipulable.
(5) finally step (4) being completed the two-layer film after contraposition is placed on exposure machine table top, is bonded on exposure machine table top by press strip F and the first film A.First film A fixes, and the second film B can freely stir.
As long as product directly overlaps PIN nail by the present invention, then expose personnel and carry out catching up with gas to expose, whole operating process only needs a people to complete, and carries out manual alignment without the need to independent contraposition personnel, then exposes personnel and exposes.
Above-described embodiment is only wherein specific implementation of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these apparent replacement forms all belong to protection scope of the present invention.
