Summary of the invention
In the past, in order to ensure the mechanical strength of parts installation position, when pasting above-mentioned reinforcing member; Because a plurality of product departments independently are installed in workpiece; So, often cross over a plurality of product departments and paste reinforcing member, in this occasion in order to reduce the man-hour of stickup; Not only reinforcing member is pasted by product department, also pastes reinforcing member in the portion of giving up.
But when pasting reinforcing member, in cancellate reinforcing pattern, metal forming is removed the easy residual bubble in position.If residual bubble, air bubble expansion when part refluxes then, thus peeling off of reinforcing member taken place.If peel off and occur over just the portion of giving up then no problem, if but feed through to product department, then can produce the problem that is difficult for being assembled on the machine.Particularly, carrying out in recent years installing based on the part of Pb-free solder, reflux temperature uprises, so peeling off of reinforcing member becomes problem.
In patent documentation 1 and patent documentation 2, do not put down in writing the generation of bubble fully and prevent.As the residual main cause of bubble, the metal forming of the clathrate of can giving an example pattern is removed the stage portion at position.
Such as, as shown in Figure 6, configuration 3 place product departments 51 on the workpiece 50 of double-faced flexible printing distributing board, in the portion that gives up 52 that is located at each product department's 51 periphery, same position, two sides in table is formed with cancellate reinforcing pattern 53 with metal forming.And, comprise the portion of giving up 52, cross over 3 product departments 51 and paste reinforcing member 54.
Fig. 7 is the enlarged drawing of the A part of Fig. 6, and Fig. 7 (a) is a vertical view, and Fig. 7 (b) is the X-X cutaway view of Fig. 7 (a).As previously mentioned; Cancellate reinforcing pattern 53 is formed at the same position on two sides in the table; Therefore metal forming remove position 55 in table the two sides with same position with equal area and relative; The thickness difference of part and the part that does not have metal forming of exposing dielectric base 56 of the metal forming of reinforcing pattern 53 is arranged, change tempestuously at the boundary member B of reinforcing pattern 53.
Fig. 8 is illustrated in the operation of pasting reinforcing member 54 on the workpiece 50 of above-mentioned double-faced flexible printing distributing board, is that the metal forming of giving up portion 52 is removed the amplification view at position 55.Among Fig. 8 (a); On two sides in the table of workpiece 50, pasted insulation with overlay film 57, from this state, such shown in Fig. 8 (b); Dispose reinforcing member 54 through binding agent 58 in face side (among this figure is upside), and side (being downside among this figure) configuration inside have the demoulding parts 59 of resiliency.And then, such shown in Fig. 8 (c), carry out crimping through decompressor from both sides up and down, paste reinforcing member 54.
At this moment, owing to the boundary member B in reinforcing pattern 53, thickness sharply changes, so also sharply variation of rigidity, and demoulding parts 59 can't adapt to the shape of stage portion, and only this part can't be guaranteed the pressure that downside is pushed to from figure.Therefore, such shown in C1 among this figure, between reinforcing member 54 and overlay film 57, produce the space, when the occasion that binding agent 58 can not fill up this space, then can residual bubble.
In order to prevent the residual of bubble, have a kind of in vacuum the method for crimping reinforcing member 54, but time that need vacuumize, the processing time is elongated, has the lower unfavorable factor of productivity.
On the other hand,, above-mentioned space is fully filled,, the rough sledding that reinforcing member flows out can take place because binding agent is soft if use flowability binding agent preferably.In addition, fill the space if the thickness of binding agent thickeied, then the thickness thickening of flexible printing patch panel itself can limit the situation of on machine, installing.
The method of in the gap of reinforcing pattern, filling the agent of thermohardening type priming coat is disclosed in the patent documentation 3; Though this method also is to fill above-mentioned space; But the thickness thickening of flexible printing patch panel itself, and, the operation cost rising of filling the priming coat agent increased thereby also have; Simultaneously, the rough sledding of the flexibility variation of flexible printing patch panel.
Therefore, the objective of the invention is to,, prevent residual bubble in the reinforcing pattern of being located at the portion that gives up on every side of product department passing through decompressor when a face of double-faced flexible printing distributing board is pasted reinforcing member.
The present invention proposes in order to achieve the above object, and scheme 1 described invention provides a kind of flexible printing patch panel, and it is included in the product department that forms Wiring pattern on the metal forming; Be arranged on this product department around, formed the portion that gives up of the reinforcing pattern of metal forming, on a face of this flexible printing patch panel, contact reinforcing member; And contact, overlapping demoulding parts on another face; Carry out crimping through decompressor, paste above-mentioned reinforcing member and form, it is characterized in that; In the above-mentioned reinforcing pattern of giving up portion everywhere; The two sides is oppositely arranged metal forming and removes the position in the table of flexible printing patch panel, and the metal forming of pasting a face of above-mentioned reinforcing member is removed the position and formed to such an extent that to remove the position than the metal forming of another face big.
According to this scheme; The metal forming that is formed on the reinforcing pattern of the portion of giving up is removed position area difference on two sides in the table of flexible printing patch panel; The metal forming of pasting a face of reinforcing member is removed the position and is formed to such an extent that to remove the position than the metal forming of another face big; Thus, stagger in the metal forming of the metal forming of the face boundary member of removing the position and another face position of removing the boundary member at position.Therefore, there are part and the thickness of the part that do not have of the metal forming of reinforcing pattern to change interimly.For this reason, to remove the varied in thickness at position slow for metal forming when pasting reinforcing member, so demoulding parts are followed easily, is difficult to residual bubble.
According to this scheme, remove the inboard of the opening edge portion at position in the metal forming of a face pasting reinforcing member, the metal forming that disposes another face is removed the opening edge portion at position; The boundary member of above-mentioned another metal forming staggers to the inside, thickness is changed interimly, therefore; When pasting reinforcing member through decompressor; Demoulding parts are followed the varied in thickness of boundary member on one side, Yi Bian raise, the metal forming of above-mentioned another face removes the position and demoulding parts fit tightly. interimlyTherefore, remove filling adhesive in the space between position and the reinforcing member in the metal forming of an above-mentioned face, can residual bubble.
Among the present invention, the varied in thickness of part and the part that do not have of metal forming that the portion of giving up has reinforcing pattern is slow, therefore; Even use such as cancellate reinforcing pattern; When pasting reinforcing member through decompressor, it is good that the metal forming of another face is removed the following property of demoulding parts at position, accompanies therewith; The space that the metal forming of a face is removed between position and the reinforcing member disappears, and what can prevent to bubble is residual.

Embodiment 1
The overall structure of flexible printing patch panel of the present invention and structure shown in Figure 6 are basic identical; On workpiece 50, dispose a plurality of product departments 51; In the portion that gives up 52 that is located at each product department's 51 periphery, same position, two sides in table is formed with cancellate reinforcing pattern through metal forming.And, comprise the portion of giving up 52, cross over a plurality of product departments 51 and paste reinforcing member 54.
Fig. 1 representes to be located at the metal forming of the reinforcing pattern 10 on the two sides in the table of double-faced flexible printing distributing board and removes position 11, and Fig. 1 (a) is a vertical view, and Fig. 1 (b) is that the Y-Y of Fig. 1 (a) is to cutaway view.The metal forming of this reinforcing pattern 10 is removed two sides in the table of double-faced flexible printing distributing board, position 11, relatively is formed on the same position.Among Fig. 1 (a), with the face side of the nearly body side of paper (being upside among this figure (b)) as flexible printing patch panel, then as after state; At face side configuration reinforcing member 54; And the demoulding of side configuration inside parts 59 on one side through the decompressor crimping, are pasted reinforcing member 54 on one side.
Here; The metal forming that is formed on dielectric base 12 face side is removed the size of position 11A and is removed varying in size of position 11B with the metal forming that is formed on dielectric base 12 the inside sides, and the opening that the metal forming that the metal forming of face side is removed the aperture efficiency the inside side of position 11A is removed position 11B is big.Promptly; As illustrating; The metal forming that the metal forming of face side is removed boundary member and the inside side of position 11A is removed the position of the boundary member of position 11B and is staggered slightly; Remove the inboard of the opening edge portion of position 11A in the metal forming of face side, the opening edge portion that the metal forming of configuration the inside side is removed position 11B, the thickness of boundary member separately forms according to the mode of phasic Chang.
The poor α that the metal forming that the metal forming of face side is removed boundary member and the inside side of position 11A is removed the boundary member of position 11B is more than the 0.3mm, than the short occasion of this length, after the demoulding parts 59 stated be difficult to follow stage portion, easy residual bubble.Preferably about α=0.5mm; For occasion than its length; The residual of bubble had no influence, but in the table of flexible printing patch panel the two sides, the metal forming survival rate produces bigger gap; Then bend easily or twist, therefore should be noted that in the undue occasion that increases the poor α of boundary member.
Fig. 2 is illustrated in the operation of pasting reinforcing member 54 on the flexible printing patch panel of two sides, is the local amplification view that above-mentioned metal forming is removed position 11.Fig. 2 (a) is that insulation is fitted with overlay film 13 in the two sides in the table of workpiece 50; As aforementioned; Because metal forming is removed the boundary member dislocation that the metal forming of the boundary member of removing position 11A in the metal forming of face side in position 11 and the inside side is removed position 11B, so form according to the mode of thickness phasic Chang.
From this state, such shown in Fig. 2 (b), dispose reinforcing member 54 through binding agent 58 in face side (among this figure is upside), and side (being downside among this figure) configuration inside has the demoulding parts 59 of resiliency.And then, shown in Fig. 2 (c), carry out crimping from both sides up and down through decompressor, paste reinforcing member 54.
At this moment; Because remove the boundary member that the metal forming of boundary member and the inside side of position 11A removes position 11B misplaces in the metal forming of the face side of reinforcing pattern 10; So the thickness phasic Chang, rigidity is phasic Chang also, and demoulding parts 59 are followed the variation of thickness.Therefore, shown in C2 among this figure, the space between reinforcing member 54 and the overlay film 57 diminishes, and this space can easily be filled through binding agent 58, can residual bubble.
Like this, the peeling off of the reinforcing member that can prevent when part refluxes, to cause by bubble, the productivity of flexible printing patch panel improves.
In addition, in Fig. 1, be assumed to cancellate reinforcing pattern 10, metal forming is removed position 11 and is rhombus, but is not particularly limited in this shape.In addition, if in the table of flexible printing patch panel the two sides, the metal forming survival rate produces bigger gap, then the metal forming of the face side metal forming of removing shape and the inside side of position 11A remove the shape of position 11B can be slightly different.
In Fig. 3, the metal forming of face side is removed the octangle that is shaped as of position 11A, and the metal forming of the inside side is removed the circle that is shaped as of position 11B.In this occasion, it is big that the opening that the metal forming of pasting the face side of reinforcing member 54 is removed position 11A is also removed the opening of position 11B than the metal forming of the inside side.
Here; Two sides in the table of flexible printing patch panel; The metal forming survival rate produces bigger gap; Such occasion that bends, that kind as shown in Figure 4 also can form the metal forming that adjustment metal forming survival rate uses and remove position 11C on the little metal forming of aperture area is removed the reinforcing pattern of the inside side at position 11B place.
In addition; Like this; The two sides changes the operation that metal forming is removed the size at position in the table of flexible printing patch panel, can on whole of the portion that gives up 52 of workpiece shown in Figure 6 50, implement, and at least only the portion that gives up 52 to the part of pasting reinforcing member 54 implements to get final product.Such as such shown in the image pattern 5; The end of reinforcing member 54 covers the occasion that metal forming is removed position 11; Only in the zone of pasting reinforcing member 54; The metal forming that changes face side is removed the size that the metal forming of position 11A and the inside side is removed position 11B, and in the zone of not pasting reinforcing member 54, metal forming removes that the two sides is identically formed in the big I table at position.
Have again; In the present embodiment, the surface configuration reinforcing member 54 at flexible printing patch panel disposes demoulding parts 59 inside; Carry out lamination through decompressor; If but remove the face side configuration reinforcing member 54 of position 11A in the bigger metal forming of the aperture area with reinforcing pattern 10, and also can reinforcing member 54 and demoulding parts 59 be provided with up and down on the contrary, carry out lamination through decompressor.
In addition, only otherwise break away from purport of the present invention, the present invention can do various changes, and the present invention naturally relates to the technology of this change.
