Description

A kind of FPC with reinforced structure

Technical field

Flexible circuit board technical field is the utility model is related to, more particularly to a kind of FPC with reinforced structure.

Background technology

FPC is widely used in as the printed circuit board (PCB) that a kind of Distribution density is high, light-weight, thickness is thin, bending is good Electronics industry., it is necessary to which stick carbon fiber steel disc achievees the purpose that to improve FPC intensity in FPC production processes.But the prior art In, since the surfacing of reinforcement steel disc is smooth, the combination between reinforcement steel disc and FPC is insecure, causes reinforcement steel disc to come off, Make product rejection, add the production cost of enterprise.

Utility model content

The main purpose of the utility model is to propose a kind of FPC with reinforced structure, it is intended to simplifies structure, improves tradition FPC and reinforcement steel disc combination, improve the stability combined between the two, prevent product rejection.

To achieve the above object, the utility model proposes the FPC with reinforced structure, including FPC main bodys and a reinforcement Steel disc.The FPC main bodys are equipped with reinforcement area and non-reinforcement area, and the reinforcement steel disc is installed on the reinforcement area of the FPC main bodys, institute The rectangular setting of reinforcement steel disc is stated, and the one side that the reinforcement steel disc is contacted with the FPC is equipped with grid lines.

Preferably, the depth of the grid lines is arranged to the 1/3 of the reinforcement steel plate thickness.

Preferably, the corner of the reinforcement steel disc is provided in round chamfering.

Preferably, the reinforcement steel disc is pasted by pure glue and the FPC main bodys and fixed.

Compared with prior art, the beneficial effects of the utility model are：Simple in structure, cost is low, by reinforcement steel disc The one side contacted with FPC adds grid lines, substantially increases the stability combined between reinforcement steel disc and FPC, effectively avoids The coming off of reinforcement steel disc, prevents from product rejection from causing enterprise that the production cost increases.

Brief description of the drawings

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other attached drawings can also be obtained according to the structure shown in these attached drawings.

Fig. 1 is the structure diagram of the utility model FPC entirety；

Fig. 2 is the utility model reinforcement steel disc and the combining structure schematic diagram of FPC；

Fig. 3 is the structure diagram that the utility model reinforcement steel disc contacts one side with FPC；

The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.

Embodiment

A kind of FPC with reinforced structure that the present embodiment proposes, as shown in Figure 1, including 1 and one reinforcement steel of FPC main bodys Piece 2.The FPC main bodys 1 are equipped with reinforcement area and non-reinforcement area, and the reinforcement steel disc 2 is installed on the reinforcement area of the FPC main bodys 1. As shown in figure 3, the 2 rectangular setting of reinforcement steel disc, and the one side that the reinforcement steel disc 2 is contacted with FPC main bodys 1 is equipped with grid lines 3, it should be noted that the grid lines 3 is formed by chemical medicinal liquid etching.By being connect in reinforcement steel disc 2 and FPC main bodys 1 Tactile one side sets grid lines 3, effectively prevent since 2 surfacing of reinforcement steel disc is smooth, cause reinforcement steel disc 2 easily from The risk to come off in FPC main bodys 1, improves the stability combined between reinforcement steel disc 2 and FPC main bodys 1, ensure that the good of product Rate, greatly reduces the scrappage of product, has saved the production cost of enterprise.

Further, the depth of grid lines 3 is arranged to the 1/3 of 2 thickness of reinforcement steel disc, is improving reinforcement steel disc 2 and FPC Between main body 1 on the basis of linking steady character, the rigidity of reinforcement steel disc 2 ensure that, make reinforcement steel disc 2 will not be because of grid lines 3 Setting cause rigid reduction, influence strengthening action of the reinforcement steel disc 2 to FPC.

Further, the corner of reinforcement steel disc 2 is provided in round chamfering 4, and since reinforcement steel disc 2 is relatively thin, corner is sharp, Rounded corners 4 are set effectively to prevent operating personnel's scratching fingers during being installed to reinforcement steel disc 2, to operating personnel Safe operation protected.

Further, as shown in Fig. 2, reinforcement steel disc 2 pastes fixation by pure glue 5 and FPC main bodys 1, further increase Combination stress between reinforcement steel disc 2 and FPC main bodys 1, greatly reduces the risk that reinforcement steel disc 2 comes off from FPC main bodys 1, protects The yield of product is demonstrate,proved.

It these are only the preferred embodiment of the utility model, it does not limit the scope of the patent of the present invention, every Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in Other related technical areas, are equally included in the patent within the scope of the utility model.
