Abstract
The utility model discloses a flexible printed circuit board with pad reinforcement steel sheet, include FPC body (4) and set up at positive at least one NULL of FPC body, the NULL welding is on FPC body positive IC pad (2), be equipped with golden finger (3) on the FPC body, be equipped with reinforcement steel sheet (1), the regional region overlapping that encloses with the IC pad in reinforcement steel sheet place at the back of FPC body. The regional area in reinforcement steel sheet place is greater than the IC pad and encloses regional area, the region that the IC pad encloses contains reinforcement steel sheet place region. Be the back that the reinforcement steel sheet just is located the IC pad, the reinforcement is carried out to IC pad and NULL exactly to its purpose. The thickness of reinforcement steel sheet is 0.1mm. The golden finger has 249 golden finger pads. This flexible printed circuit board with pad reinforcement steel sheet can carry out the reinforcement to the IC pad, prevents the production of rosin joint, and the reliability is high.
Description
Technical field
The utility model relates to a kind of flexible print circuit board with pad reinforcement steel disc.
Background technology
Existing flexible print circuit board, its FPC body is provided with integrated chip (IC), because the leg of interior pin IC own only has 0.25MM length, due to the reinforcement measure not for IC pad, FPC when point plate or client use because of misoperation, easily cause IC rosin joint, therefore, be necessary to design a kind of novel flexible print circuit board with pad 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 pad reinforcement steel disc, and this flexible print circuit board with pad reinforcement steel disc can carry out reinforcement to IC pad, and prevent the generation of rosin joint, reliability is high.
The technical solution of utility model is as follows:
There is a flexible print circuit board for pad reinforcement steel disc, comprise FPC body (4) and be arranged at least one integrated chip in FPC body front; Integrated chip is welded on the IC pad (2) in FPC body front; FPC body is provided with golden finger (3); Reinforcement steel disc (1) is provided with, the region overlapping that reinforcement steel disc region and IC pad surround at the back side of FPC body.
The area of reinforcement steel disc region is greater than the area that IC pad surrounds region; The region that IC pad surrounds comprises reinforcement steel disc region.Namely reinforcement steel disc is just positioned at the back side of IC pad, and its object carries out reinforcement to IC pad and integrated chip exactly.
The thickness of reinforcement steel disc is 0.1mm.
Golden finger has 249 golden finger pads.
Reinforcement steel disc is positioned at the zone line of FPC main body.
Beneficial effect:
The flexible print circuit board with pad reinforcement steel disc of the present utility model, owing to adopting reinforcement steel disc to carry out reinforcement to IC pad pointedly, FPC when point plate or client use because of misoperation time, also effectively can prevent the generation of rosin joint, reliability is high.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram with the flexible print circuit board of pad reinforcement steel disc of the present utility model.
Fig. 2 is the structure schematic diagram with the flexible print circuit board of pad reinforcement steel disc of the present utility model.
Label declaration: 1-reinforcement steel disc, 2-IC pad, 3-golden finger, 4-FPC body.
