Abstract
The utility model discloses a flexible printed circuit board with reinforcement steel sheet, including FPC main part (6) and FPC tip, the FPC tip links to each other with the FPC main part, the front of FPC tip is equipped with the golden finger, and the back of FPC tip is equipped with reinforcement steel sheet (5), and its characterized in that is equipped with a plurality of exhaust hole (3) on the reinforcement steel sheet. The FPC tip is equipped with circular shape chamfer (2) with the continuous department of FPC main part. The following boundary line of reinforcement steel sheet and the following boundary line parallel and level of FPC tip, the upper boundary line of reinforcement steel sheet lies in the outside in golden finger the higher authority boundary line. The boundary line is at a distance of 0.73mm above the upper boundary line of reinforcement steel sheet and the golden finger. Foaming when this flexible printed circuit board with reinforcement steel sheet can prevent to weld and cause the connector rosin joint.
Description
Technical field
The utility model relates to a kind of flexible print circuit board with reinforcement steel disc.
Background technology
The existing flexible print circuit board with reinforcement steel disc, see Fig. 1, when paster, cause connector paster rosin joint because high temperature impact causes PI to bubble, cause product bad, in addition, original FPC, easily to go out to fracture golden finger pad at golden finger, therefore, be necessary to design a kind of novel flexible print circuit board with reinforcement steel disc.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of flexible print circuit board with reinforcement steel disc, and this flexible print circuit board with reinforcement steel disc can prevent foaming when welding and cause connector rosin joint.
The technical solution of utility model is as follows:
There is a flexible print circuit board for reinforcement steel disc, comprise FPC main body (6) and FPC end; FPC end is connected with FPC main body; The front of FPC end is provided with golden finger, and the back side of FPC end is provided with reinforcement steel disc (5), it is characterized in that, reinforcement steel disc is provided with multiple steam vent (3).
The connecting place of FPC end and FPC main body is provided with circular chamfering (2).
The following boundary line of reinforcement steel disc is concordant with the following boundary line of FPC end; The upper border line of reinforcement steel disc is arranged in the outside (i.e. the upside of Fig. 3) of golden finger upper border line.
The upper border line of reinforcement steel disc and golden finger upper border line are at a distance of 0.73mm.
Beneficial effect:
The flexible print circuit board with reinforcement steel disc of the present utility model, devise steam vent, the generation of bubble when avoiding PI to be heated, ensure the reliable welding of connector, in addition, reinforcement steel disc in the outside of golden finger upper border line, more in the outside of coboundary, FPC end, good protection can be provided to FPC end and golden finger like this, golden finger pad can be prevented from fractureing at PI place.
Accompanying drawing explanation
Fig. 1 is the structural representation that existing reinforcement steel disc is pasted onto the back side, FPC end;
Fig. 2 is the Facad structure schematic diagram with the flexible print circuit board of reinforcement steel disc of the present utility model;
Fig. 3 is the structure schematic diagram with the flexible print circuit board of reinforcement steel disc of the present utility model.
Label declaration: 1-golden finger, 2-chamfering, 3-steam vent, 4-golden finger upper border line, 5-reinforcement steel disc, 6-FPC main body.
