Description
Technical field
The utility model relates to FPC and manufactures field, is specifically related to a kind of heat radiation and jamproof FPC.
Background technology
FPC(Flexible Printed Circuit flexible print circuit) as a kind of have excellent reelability circuit board, because its frivolous property use is more extensive, as the connection line plate as between mobile phone camera and mainboard, but because camera caloric value in the time working is larger, especially high-pixel camera head, easily there is the heating of camera position, light for a long time the problems such as the stuck job insecurity of picture causing, and because other electronic component work meetings of mobile phone produce and disturb the signal of camera transmission, there is flower screen phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of heat radiation and jamproof FPC and solves the problems such as the stuck job insecurity of face that causes due to camera heating cause in prior art, and the easily influenced problem that causes flower screen of signal transmission.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of heat radiation and jamproof FPC; comprise FPC plate body; described FPC plate body is provided with diaphragm; between described FPC plate body and diaphragm, be connected by glue-line; on the ground pad of described FPC plate body, be provided with the pad district of windowing; described ground pad is arranged on the printed circuit board (PCB) of BGA(Ball Grid Array ball grid array structure) reverse side, on described FPC plate body, the pad correspondence in district of windowing is fitted with steel disc.
On the basis of technique scheme, the utility model can also do following improvement.
Further, the described pad Wei Loutong district of district of windowing, described Lou Tong district is by conducting resinl and steel disc laminating;
Further, described pad is ground pad;
Further, the windowing area of described pad accounts for bonding pad area 50% to 70%;
Further, described conducting resinl is material filling type conducting resinl;
Further, described conducting resinl is hot pressing conducting resinl;
Further, on described FPC plate, be also provided with electromagnetic shielding film;
Further, the material of described glue-line is epoxy resin or acrylic.
The beneficial effects of the utility model are: the utility model is by the Lou copper processing of windowing on the ground pad at FPC plate, the steel disc of fitting thereon again, be steel disc and the conducting of FPC plate, due to steel disc itself is reasonable electric conductor and heat carrier, be after the laminating of FPC plate, heat conducts on steel disc, can increase radiating effect, after steel disc ground connection, can further strengthen the earthing effect of FPC plate, and then the antijamming capability of enhancing FPC plate, the strength ratio of steel disc itself is higher, can be to the FPC plate reinforcement of steel disc joint place, electromagnetic shielding film on FPC plate can further improve the antijamming capability of FPC plate.
Brief description of the drawings
