Abstract

The utility model discloses a kind of flexible circuit board reinforcement structures, include: FPCB layers, glue-line, stiffening plate, and glue-line is located at the outer surface of FPCB layers of substrate, and stiffening plate is Nian Jie with glue-line pressing, and stiffening plate is network.Glue-line is set by the substrate surface in flexible circuit board, stiffening plate and glue-line with network are press-fitted together as one structure, and the hardness of FPCB is enhanced while not increasing FPCB thickness itself, solves excessively soft in FPCB production process, the low problem of yield.

Description

A kind of flexible circuit board reinforcement structure

Technical field

The utility model relates to flexible circuit board technical field, specially a kind of flexible circuit board reinforcement structure.

Background technique

As flexible circuit board (FPCB) is using more and more extensive, people propose flexible circuit board higher and higher It is required that need to do flexible circuit board is thinner, or even needs to be as thin as 0.08mm, such situation undoubtedly gives actually production operation In bring huge quality problems.Find after study, mainly FPCB it is excessively soft caused by quality problems.

In order to solve the problems, such as that FPCB is excessively soft, people use a variety of proof schemes such as: increasing FPCB Material Strength, increase Strong FPCB material thickness, enhancing FPCB copper foil intensity, enhancing FPCB Jelly strength, finally fail to the very good solution problem.

Therefore a kind of new scheme is needed to solve the above problems.

Utility model content

Technical problem to be solved by the utility model is: a kind of flexible circuit board reinforcement structure is provided, to solve FPCB Cross soft problem.

The utility model is to solve a kind of technical solution that its technical problem provides to be:

A kind of flexible circuit board reinforcement structure, includes FPCB layers, glue-line, stiffening plate, and the glue-line is located at described FPCB layers The outer surface of substrate, the stiffening plate is Nian Jie with glue-line pressing, and the stiffening plate is network.

As an improvement of the above scheme, the size of grid is 0.4mm × 0.4mm in the stiffening plate.

As a further improvement of the foregoing solution, the stiffening plate is copper sheet.

As an improvement of the above scheme, the grid in the stiffening plate is evenly distributed in the stiffening plate.

The advantageous effects of the utility model are: glue-line is arranged by the substrate surface in flexible circuit board, has net The stiffening plate and glue-line of lattice structure are press-fitted together as one structure, and the hard of FPCB is enhanced while not increasing FPCB thickness itself Degree, solves excessively soft in FPCB production process, the low problem of yield.

Detailed description of the invention

Illustrate the technical scheme in the embodiment of the utility model in order to clearer, it below will be to required in embodiment description Attached drawing to be used briefly describes.

Fig. 1 is a kind of schematic diagram of embodiment of the utility model；

Fig. 2 is the structural schematic diagram in Fig. 1 at A；

Fig. 3 is a kind of schematic diagram of embodiment of the utility model stiffening plate.

Specific embodiment

It is carried out with reference to embodiments with technical effect of the attached drawing to the design of the utility model, specific structure and generation clear Chu is fully described by, to fully understand the purpose of this utility model, scheme and effect.It should be noted that in the feelings not conflicted The features in the embodiments and the embodiments of the present application can be combined with each other under condition.Furthermore used in the utility model it is upper, Under, the descriptions such as left and right be only in opposite figure for each component part mutual alignment relation of the utility model.

Fig. 1 is a kind of schematic diagram of embodiment of the utility model, and Fig. 2 is the structural schematic diagram in Fig. 1 at A, with reference to Fig. 1 And Fig. 2, the flexible circuit board reinforcement structure of the utility model include flexible circuit board layer 10, the glue-line positioned at 10 top of FPCB layer 20, glue-line 20 is coated on the substrate of flexible circuit board 10, the stiffening plate 30 positioned at 20 top of glue-line, stiffening plate 30 and glue-line 20 Between be bonded as one formula structure by pressing.Stiffening plate 30 is equipped with equally distributed grid 31, so that stiffening plate 30 is being protected There is rigidity well while holding frivolous state, meet the reinforcing requirement of FPCB layer 10.Claims use " FPCB layers ", It is recommended that unified with one.

The material of preferred stiffening plate 30 is copper, so that latticed stiffening plate 30 has one while ensureing its intensity Fixed toughness improves the adaptability of stiffening plate 30, reliability.

Fig. 3 is a kind of structural schematic diagram of the embodiment of the utility model stiffening plate 30, and with reference to Fig. 3, stiffening plate 30 is whole For regular shape, equally distributed grid 31 is equipped in stiffening plate 30, the size of preferred grid 31 is 0.4mm × 0.4mm, Grid keeps the thickness for making grid difficulty of processing, the intensity of grid, the weight of stiffening plate 30 and stiffening plate 30 in this size It spends size and keeps preferable balance, stiffening plate has good cost performance.

It can be seen from the above, the flexible circuit board reinforced structure of the utility model, is bonded by pressing on flexible circuit board Grid stiffening plate made of copper, improves the intensity of flexible circuit board, further also significantly improves flexible circuit board and is producing Product yield in the process.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered This is understood, in the spirit and scope for not departing from the utility model defined by described claims, in form and details On the utility model can be made a variety of changes, be the protection scope of the utility model.
