Abstract
The utility model discloses a white cover film with good light shielding performance for a flexible printed circuit board. The white cover film is characterized in that the white cover film has a layered structure, which includes a first white ink layer, a second electrical insulation layer, a third adhesive layer and a fourth protection layer; and the white ink layer, the electrical insulation film layer, the adhesive layer and the protection layer are bonded together in sequence from top to bottom. Compared with the prior art, the white cover film has the advantages of good light shielding performance, high light reflectivity, and excellent binding property and heat resistance.
Description
Technical field
The utility model relates to a kind of white coverlay that the flexible printed circuit board of rotary light performance is revolved in better screening that has, and this white coverlay has better screening and revolves rotary light performance, and has higher reflecting rate and good rerum natura.
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 optical activity is revolved in the screening of the vitals coverlay in the product itself, reflective is low, apply the printing ink of white again to improve light reflectance after need handling PCB surface, technology is loaded down with trivial details, and white ink comes off easily, flavescence, poor heat resistance.Therefore, along with the development of electronic industry, the flexible printed circuit board material that light-proofness is good, reflecting rate is high, caking property is good and thermal endurance is outstanding will be favored.
The utility model content
The purpose of this utility model provides the white coverlay that the flexible printed circuit board of rotary light performance is revolved in better screening that has that a kind of shading performance is good, reflecting rate is high.
This purpose of the present utility model realizes by following technical solution: have the white coverlay that the flexible printed circuit board of rotary light performance is revolved in better screening; it is characterized in that: described white coverlay is a layer structure; it has the white ink layer, the electric insulation layer that is positioned at the second layer that are positioned at ground floor, is positioned at the 3rd layer adhesive layer and is positioned at the 4th layer protective layer, and described white ink layer, electric insulation rete, adhesive layer and protective layer fit together from top to bottom.
The material of described electric insulation rete is polyimide 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, it is good that rotary light performance is revolved in white coverlay screening of the present utility model, reflecting rate height, caking property and fine heat-resisting performance.
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; it has the white ink layer 1, the electric insulation rete 2 that is positioned at the second layer that are positioned at ground floor, is positioned at the 3rd layer adhesive layer 3 and is positioned at the 4th layer protective layer 4, and white ink layer 1, electric insulation rete 2, adhesive layer 3 and protective layer 4 four fit together from top to bottom.
The material of electric insulation rete 2 is a poly (ethylene naphthalate) film, also can adopt polyimide film, and the material of protective layer 4 is a polyethylene film, also can adopt polypropylene screen, polyester film, applying paper or pearl paper.
