Abstract
The utility model discloses a white cover layer for flexible printed circuit board. The white cover layer has a lamellar structure, and has a transparent electric insulation film layer located at the top layer, a white adhesive layer with higher reflecting rate located at a central layer and a protection layer located at the bottom layer, wherein the electric insulation film layer, the white adhesive layer and the protection layer are attached together from top to bottom. Compared with existing technology, the white adhesive layer of the utility model has good lightproof performance, high reflecting rate, reduced production costs; and saves a process for recoating one layer of white ink.
Description
Technical field
The utility model relates to a kind of white coverlay that is used for flexible printed circuit board, and this white coverlay has higher reflecting rate.
Background technology
Along with the design of mobile phone and other electronic product is weeded out the old and bring forth the new, special designing requirement for flexible printed circuit board is arranged, and in recent years, LED Lighting Industry high speed development, because the luminous power of LED own has it restricted, therefore also update in the hope of helping LED luminous (optically focused) effect in the encapsulation technology of LED, backboard---the flexible circuitry panel products that tradition LED uses, particularly the vitals coverlay in the product is the individual layer membrane structure, the light-proofness of coverlay itself is relatively poor, reflective is low, the printing ink that needs to apply white again forms the white ink layer, to improve light reflectance.Can cause technology loaded down with trivial details but add inking, processing cost rises, and also can cause rate of finished products to reduce.Therefore, along with the development of electronic industry, light-proofness is good, and the integrally-built flexible printed circuit board coverlay that reflecting rate is high will be favored.
The utility model content
The purpose of this utility model provides that a kind of shading performance is good, the white coverlay that is used for flexible printed circuit board that reflecting rate is high.
This purpose of the present utility model realizes by following technical solution: the white coverlay that is used for flexible printed circuit board; it is characterized in that: described white coverlay is a layer structure; its have the transparence that is positioned at top layer the electric insulation rete, be positioned at having than the white adhesive layer of high reflecting rate and being positioned at the protective layer of bottom of intermediate layer, described electric insulation rete, white adhesive layer and protective layer three fit together from top to bottom.
The material of described electric insulation rete is PETG film or poly (ethylene naphthalate) film.
The material of described protective layer is polyethylene film, polypropylene screen, polyester film, applying paper or pearl paper.
Compared with prior art, white coverlay of the present utility model is because the intermediate layer is a white adhesive layer than high reflecting rate, and the shading performance of whole coverlay is good, the reflecting rate height, and can save the operation that is coated with white ink layer again, reduce production costs.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 is the structural representation of the utility model white coverlay.
Embodiment
The white coverlay that is used for flexible printed circuit board as shown in Figure 1; this white coverlay is a layer structure; its have the transparence that is positioned at top layer electric insulation rete 1, be positioned at having than the white adhesive layer 2 of high reflecting rate and being positioned at the protective layer 3 of bottom of intermediate layer; electric insulation rete 1, white adhesive layer 2 and protective layer 3 threes fit together from top to bottom; this white coverlay is owing to contain the white adhesive layer; the shading performance is good, the reflecting rate height.
The material of electric insulation rete 1 is a poly (ethylene naphthalate) film, also can adopt the PETG film, and the material of protective layer 3 is a polyethylene film, also can adopt polypropylene screen, polyester film, applying paper or pearl paper.
