Description

Composite reinforcing film and manufacturing approach thereof
Technical field
The invention belongs to flexible print wiring board processing and manufacturing technical field, be specifically related to a kind of composite reinforcing film and manufacturing approach thereof that is used for lamination reinforcement.
Background technology
Flexible print wiring board (being also referred to as FPC), characteristics are compact, therefore in use are easy to generate bending, scar etc.; Mechanical strength is little, is prone to be full of cracks.So generally all need carry out lamination reinforcement to it handles.The purpose of lamination reinforcement is in order to strengthen the mechanical strength of FPC, to make things convenient for mounted on surface part etc.The reinforced rubber sheet type is multiple; Decide according to the goods instructions for use is different; Mainly contain polyphenyl dioctyl phthalate glycol ester (being also referred to as PET), polyimides (being also referred to as PI), (gum is a kind of show and colour to gum; Generally be to make by the mucigel of one deck PP paper and a skim and centre thereof), metal or resin stiffening plate or the like.
The technological process that traditional use polyimides film carries out reinforcement is:
1. get the raw materials ready: the polyimides reinforcing film that is ready to be provided with successively lamination film layer and release rete; Said lamination film layer comprises polyimide layer and is used to bond the gluing layer of said release rete; So-called release rete is to stick to being used on the gluing layer to avoid the gluing layer before fitting, to attach the thin film of dust;
2. die-cut slivering: the polyimides reinforcing film is along crossline direction, die-cut according to predetermined width, obtain the polyimides reinforcing film of a plurality of horizontal stripe shapes;
3. die-cut in flakes: along the in-line direction of polyimides reinforcing film, die-cut again according to predetermined width, obtain the polyimides reinforcing film of a plurality of sheets;
4. monolithic tears mould release membrance: get the polyimides reinforcing film of each sheet, peel off its mould release membrance, obtain having the applying film of polyimide layer and gluing layer;
5. monolithic is fitted: the reinforcement applying is carried out in the preset reinforcement position of the gluing layer of applying film being aimed at flexible print wiring board.
The die-cut sheet reinforcing film that obtains is very little, that have even big less than nail cover in the cause more and more miniaturization of product now, above-mentioned steps 3.; Cause above-mentioned steps 4. in, the operation that the operating personnel peels off mould release membrance is wasted time and energy, operating efficiency is lower; Contraposition also is difficult to accurately, and the product yield is low.
Summary of the invention
The purpose of this invention is to provide a kind of lamination reinforcement and operate the comparatively composite reinforcing film of quick and convenient.
Another object of the present invention provides the preparation method of above-mentioned composite reinforcing film.
The technical scheme that realizes first purpose of the present invention is: a kind of composite reinforcing film, comprise lamination film layer, and said lamination film layer comprises strengthening course and adhesive layer; The tow sides of said lamination film layer all are stained with little mucous membrane of whole; Said lamination film layer is formed by the applying membrane combination of a plurality of sheets that are arranged side by side, and adjacent respectively fitting broken off between the diaphragm each other.
In the such scheme, the adhesion between used little mucous membrane and the lamination film layer MR medium reinforcing layer is less than the adhesion between the rete of the preset reinforcement position of adhesive layer and flexible print wiring board in the said lamination film layer.
In the such scheme, said strengthening course material therefor is polyphenyl dioctyl phthalate glycol ester, polyimides, metal or polypropylene.
In the such scheme, said strengthening course material therefor preferably adopts polyphenyl dioctyl phthalate glycol ester, polyimides or polypropylene.
In the such scheme, said lamination film layer is to be combined by the identical applying diaphragm repeated arrangement of a plurality of sizes; Said adhesive layer is gluing layer or hot sealing layer.
The technical scheme that realizes second purpose of the present invention is: a kind of manufacturing approach of composite reinforcing film may further comprise the steps:
1. get the raw materials ready: the raw material film that is ready to be provided with successively lamination film layer and release rete; Said lamination film layer comprises strengthening course and the adhesive layer that is used to bind said strengthening course and release rete;
2. be die-cut into horizontal stripe: the raw material film is along crossline direction, die-cut according to predetermined width, obtain the raw material film of a plurality of horizontal stripe shapes;
3. tear mould release membrance: peel off the release rete on the horizontal stripe shape raw material film, obtain the applying film of a plurality of horizontal stripe shapes;
4. positive and negative pastes little mucous membrane: the tow sides at a plurality of horizontal stripe shape applying films are all pasted little mucous membrane of one whole; Make said a plurality of horizontal stripe shape applying film be bonded to an integral body by little mucous membrane; Thereby be provided with little mucous layer successively;, lamination film layer and little mucous layer, the semi-finished product composite reinforcing film;
5. be die-cut into taeniae: along the in-line direction of semi-finished product reinforcing film, die-cut again according to predetermined width, obtain the finished product composite reinforcing film of a plurality of taeniae shapes; Between two-layer little mucous membrane, comprise a plurality of sheets and the applying diaphragm that breaks off each other about in this finished product composite reinforcing film.
In the said method, the adhesion between used little mucous membrane and the lamination film layer MR medium reinforcing layer is less than the adhesion between the rete of the preset reinforcement position of adhesive layer and flexible print wiring board in the said lamination film layer.
In the said method, said strengthening course material therefor is polyphenyl dioctyl phthalate glycol ester, polyimides, metal or polypropylene.
In the said method, said strengthening course material therefor preferably adopts polyphenyl dioctyl phthalate glycol ester, polyimides or polypropylene.
In the said method, said lamination film layer is to be combined by the identical applying diaphragm repeated arrangement of a plurality of sizes; Said adhesive layer is gluing layer or hot sealing layer.
The present invention has positive effect: in (1) composite reinforcing film of the present invention, comprise lamination film layer, said lamination film layer comprises strengthening course and adhesive layer; The tow sides of said lamination film layer all are stained with little mucous membrane of whole; Said lamination film layer is formed by the applying membrane combination of a plurality of sheets that are arranged side by side, and adjacent respectively fitting broken off between the diaphragm each other.In use, the composite reinforcing film of the whole piece of taking peels off and sticks to the little mucous membrane on the adhesive layer in the lamination film layer; The applying diaphragm that exposes sheet and break off each other; Fit one by one again, avoided in the conventional method, because the too small shortcoming that is difficult to peel off fast mould release membrance of applying diaphragm.
(2) the inventive method operation is convenient, can effectively implement fast, is fit to various single-sided lamination reinforcement technologies.
