Description
Technical field
The moulding compacting that the present invention relates in the operation of making precision equipment parts such as copper-surfaced laminated plate, flexible printed board, ceramic laminated plate, to use is with fender (below, be abbreviated as fender sometimes), and relates to the fender with excellent in cushioning properties.
Background technology
Goods (laminated product) with laminated construction for example are clamped between a plurality of heat dishes, make through the hot pressing that utilizes this heat dish to carry out.
The laminated product of making by this method one for example said down.In addition, except the example shown in following, also have goods miscellaneous in the laminated product.
(1) becomes the laminated plate of the substrate of printed wiring board
As this laminated plate, the paper phenol laminated plate that formed by brown paper and phenol resin, weaving cotton cloth and glass epoxide laminated plate that epoxy resin forms etc. by glass fibre are arranged.
(2) printed wiring board
As this laminated plate, have in the one side of substrate to be formed with a printed wiring board of conductive pattern, to be formed with the two-face printing wiring plate of conductive pattern on the two sides of substrate, not only also to be formed with the multilayer printed-wiring board of conductive pattern etc. in the outside of substrate but also in inside.
(3) flat-panel monitor: LCD, electroluminescent etc. are arranged.
(4) semiconductor packages: have with the chip size packages of chip approximate same size (Chip Size Package, CSP) etc.
Making in the operation of these various laminated products (by formed body), between heat dish and laminated product, there is fender with the moulding pressure setting.This fender has resiliency, makes the heat dish can directly not contact with laminated product, and performance will be conducted to the function of whole of laminated product equably by the heat that the heat dish produces.
The concrete use-case that makes of this fender is described based on Fig. 1.
Fig. 1 is the sectional view that shows an example of moulding pressure setting in the manufacturing installation of two-face printing wiring printed panel, laminated plate.In the moulding pressure setting shown in Figure 1, a pair of heat dish 40 of arranged opposite, a pair of mirror board 50, Copper Foil 60 and the prepreg 70 that disposes in the inner part than a pair of fender C of a pair of heat dish 40 configuration in the inner part, than a pair of fender C have been used.
Finally, form two-face printing wiring plate (laminated product) through prepreg 70 and Copper Foil 60.Carry out the overlapping prepreg 70 that constitutes through polylith is contained the sheet material that epoxy resin dipping becomes semi-cured state in glass cloth.
In the moulding pressure setting, apply heat and pressure through heat dish 40,40, carry out moulding, the condition of molding of this moment is according to the difference of the cooperation of epoxy resin raw material etc. and difference.In addition, if the hot transfer amount of the fender that uses in the molding procedure (programming rate: ℃/minute) does not meet and creates conditions, then might produce poor properties in the laminated product.In addition,, need apply certain pressure and heat, but in whole of fender, must be uniform heat and the pressure that laminated plate applies in order to make the laminated product of homogeneous.In Fig. 1, make the fender C that has flat board between heat dish 40 and the prepreg 70 with such formation, carry out hot pressing.But if carry out such hot pressing repeatedly, then the fender surface with heat dish 40 and/or mirror board 50 butts becomes too level and smooth, and visible fender C is pasted on the phenomenon of heat dish 40 and/or mirror board 50.
Particularly; At fender is under the situation of acupuncture (needle punch) type; Concavo-convex (pin hole of acupuncture concavo-convex) on fender surface since fender use repeatedly thus the winding of fiber lax; Therefore the roughness on fender surface reduces and smoothing, thereby visible fender is pasted on the phenomenon of heat dish 40 and/or mirror board 50.
That is, repeated hot number of times (moulding compacting number of times) is many more, and then the fender surface is level and smooth more, and it is many more therefore to paste phenomenon.If fender C is pasted on heat dish 40 and/or mirror board 50, then can hinder the manufacturing of laminated product after this, therefore must exchange buffering material C.
, now commercially available fender has used the fender of the various kinds such as laminated body of rubber, felted goods (nonwoven etc.), rubber and felt.Though be devoted to make the laminated product of homogeneous recently, requirement can avoid fender to be pasted on the fender of the phenomenon of heat dish and/or mirror board.
All the time, use fender, in patent documentation 1, put down in writing to use and above-mentioned passed through acupuncture and incorporate felted nonwoven has improved the fender of resiliency and heat transmitting as moulding compacting.
For example, as such fender, fender shown in Figure 2 is arranged.In Fig. 2, fender C4 is by being formed by the felt material 11A lamination of acupuncture in matrix 11B and 2 layers of staple (staple fiber) in the table of matrix 11B.
Here, staple is that aromatic polyamide and polybenzazole fiber constitute by a position.In addition, matrix 11B has used by the warp thread 11B1 that comprises heat resistant fibre and weft yarn 11B2 and weaving cotton cloth of forming.If use this fender,, also to a certain degree exert pressure to homogenising even then tellite has to a certain degree concavo-convex.But, if use this fender continuously, the concaveconvex shape on the fender surface that then joins with heat dish and/or mirror board (pin hole that produces by acupuncture concavo-convex) smoothing, therefore visible fender is pasted on the phenomenon of heat dish and/or mirror board.
In addition, use fender, in patent documentation 2, put down in writing a kind of fender that comprises hear resistance rubber as in the past moulding compacting, its be to use contain be soaked with heat-resistant resin glass cloth as core, make aluminium sheet be bonded in the fender of superficial layer.This fender is in the manufacturing process of flexible printed board; Make when being coverlay and the flexible base, board crimping of base material with the polyimides mesentery; Can tackle the generation in the space that results from the concavo-convex of wiring portion and produce; But use this fender, the convex-concave surface on the fender surface (is the coverlay of base material with the polyimides mesentery) that joins with heat dish and/or mirror board also can the smoothing along with the continuous use of fender, and therefore visible fender C is pasted on the phenomenon of heat dish and/or mirror board.
