Description
Technical Field
The utility model relates to the technical field of flexible circuit board materials and flexible circuit board production.
Background
The flexible printed circuit board is made of polyimide or polyester film as a base material and has high reliability and excellent flexibility; the wiring density is high, the weight is light, the thickness is thin, and the flexibility is good; the utility model 201120096808.6 discloses a flexible copper-clad plate which is formed by Cu (copper) +AD (adhesive) +PI (polyimide film), wherein the flexible copper-clad plate cannot achieve a shading effect, and the FPC manufacturer has a shading performance effect for a product, and can use a black covering film material to be attached to the other side to achieve the shading performance.
Disclosure of Invention
The utility model aims to realize the shading performance and solve the problems of high material cost, long processing flow, low production yield, increased structure thickness and reduced flexibility in the prior art.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the flexible copper-clad plate with the light shielding performance comprises a copper foil and a polyimide film, wherein one surface of the polyimide film is coated with light shielding ink, the other surface of the polyimide film is coated with an epoxy resin adhesive, and the copper foil and the polyimide film are mutually fixed and adhered through the epoxy resin adhesive.
The beneficial effects of the utility model are as follows: according to the utility model, the polyimide film is used as a base layer, the light-shielding ink is coated on one surface of the polyimide film, and the polyimide film is adhered on the other surface of the polyimide film through the epoxy resin adhesive, so that the flexible board body is composed of the polyimide film, the epoxy resin adhesive, the polyimide film and the light-shielding ink.
Drawings
Fig. 1 is a schematic cross-sectional view of the present utility model.
The reference numerals are:
polyimide film 1, epoxy adhesive 2, copper foil 3, and light-shielding ink 4.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The flexible copper clad laminate with the light shielding performance shown in fig. 1 comprises a copper foil 3 and a polyimide film 1, wherein one surface of the polyimide film 1 is coated with light shielding ink 4, the other surface of the polyimide film 1 is coated with an epoxy resin adhesive 2, and the copper foil 3 and the polyimide film 1 are mutually fixed and adhered through the epoxy resin adhesive 2.
The polyimide film 1 is used as a base layer, and the light shielding ink 4 is coated on one surface of the polyimide film 1, and the polyimide film 1 is adhered to the other surface of the polyimide film 1 by the epoxy adhesive 2, so that the flexible board body is composed of the polyimide film 1, the epoxy adhesive 2, the polyimide film 1 and the light shielding ink 4, namely, the composition is Cu (copper foil 3) +AD (epoxy adhesive 2) +PI (polyimide film 1) +the light shielding ink 4.
The utility model has good shading performance by adopting shading ink 4; compared with the black covering film material in the prior art, the shading ink 4 has the advantages of low material cost, short processing flow, high production yield, reduced structure thickness and improved bending property.
The above disclosure is only a preferred embodiment of the present utility model, and the scope of the present utility model is not limited thereto, so that the present utility model is not limited to the above embodiments, and any modifications, equivalents and modifications made to the above embodiments according to the technical principles of the present utility model are still within the scope of the present utility model.
