Abstract
The utility model relates to the field of FPC, and especially to an anti-interference open-circuit-preventive FPC. The anti-interference open-circuit-preventive FPC comprises an FPC board, at least one end of the FPC is provided with a golden finger end, the golden finger end comprises metal wiring layers respectively arranged at the front and back sides of the golden finger end, a protectively layer is arranged between the metal wiring layers, and the metal wiring layers are both connected with lines on the FPC board. According to the utility model, the two metal wiring layers are arranged at the golden finger end and connected in parallel with the lines on the FPC board; if one metal wiring layer is disconnected due to different reasons, the other metal wiring layer can still enable the FPC to work normally, and the open-circuit-preventive performance of the FPC can be improved; and the two sides of the FPC board are additionally provided with electromagnetic films to effectively shield signal interference in cameras or displays caused by antenna radiofrequency or outside noises, and excellent performance of the cameras or displays are maintained.
Description
Technical field

Background technology
Relative general circuit plate, FPC(Flexible Printed Circuit flexible print circuit) plate is a kind of height reliability that has, excellent pliability, the circuit board with high, the lightweight and thin thickness of distribution density, be widely used in the connection of electronic device, but because golden finger place is generally one side cabling, also easily there is the problem that circuit fractures in golden finger and circuit switch place, if FPC plate as display or camera winding displacement, is prone to the display screen causing due to circuit open circuit or camera is not worked or flower screen phenomenon; And in the situation of FPC plate without electromagnetic shielding, camera or display screen are subject to antenna radio frequency and outside other noise disturbs, and occurs flower screen phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of anti-tampering anti-open circuit FPC and solves in prior art after golden finger place one side cabling easily fractures and cause open circuit, and FPC is easily affected by Electromagnetic Interference the problem that signal transmits.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of anti-tampering anti-open circuit FPC; comprise FPC plate; described FPC plate is provided with at least one golden finger end; described golden finger end comprises that correspondence is arranged on the metal wiring layer on the tow sides of golden finger end; between described metal wiring layer, be provided with protective layer, described metal wiring layer is all connected with the circuit on FPC plate.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described double layer of metal wiring layer is corresponding and Parallel Design;
Further, on two surfaces up and down of described FPC plate, be also equipped with electromagnetic membrane;
Further, described electromagnetic membrane is electromagnetic shielding film, and described electromagnetic shielding film at least comprises carrier film and metal protective film;
Further, the shape of described electromagnetic membrane is corresponding with the shape of FPC plate;
Further, the thickness of described electromagnetic membrane is no less than 12 microns;
Further, between described protective layer and metal wiring layer, by gluing, connect;
Further; described FPC plate comprises at least one deck metal level; between described every two metal layers, be provided with protective layer; in described topmost metal layer, be also provided with protective layer; on the lower surface of described orlop metal level, be also provided with protective layer; between described protective layer and metal level, by glue, on the upper surface of described the superiors protective layer, be also provided with electromagnetic membrane, on the lower surface of described orlop protective layer, be also provided with electromagnetic membrane.
The beneficial effects of the utility model are: the utility model is by designing double-sided metal wiring layer at golden finger place, and double-sided metal wiring layer is all connected in parallel on FPC circuit, in the situation that one side disconnects due to a variety of causes circuit, another side still can make FPC normally work, can improve the anti-open circuit characteristic of FPC, two sides at FPC plate all increases electromagnetic membrane, effectively masks antenna radio frequency and outside noise to camera or shows that signal frequently disturbs, and keeps camera or shows frequently good electric property.
