Abstract

A flexible circuit board capable of conveniently achieving auxiliary material gluing and counterpoint relates to the flexible circuit board processing technology field and especially relates to the monolithic gluing and counterpoint technology of the auxiliary materials, such as flexible circuit board reinforcement, a gum and the like. The flexible circuit board is characterized by: etching a paster standard counterpoint line on a copper foil plate body; etching a paster positive allowance counterpoint line and a negative allowance counterpoint line on two sides of the paster standard counterpoint line respectively. When monolithic gluing is performed, the each paster is glued between the each group of paster positive allowance counterpoint line and the negative allowance counterpoint line so that the each paster can be effectively and conveniently controlled to be laid in a tolerance range of a paster area. By using the flexible circuit board of the utility model, cost of making a special processing tool can be avoided; a utilization rate of the auxiliary material can be increased; and simultaneously processing precision of the auxiliary material can be increased and deviation can be reduced.

Description

FPC with convenient auxilliary material applying contraposition

Technical field

The utility model relates to the FPC processing technique field, auxilliary material monolithic applying technique of counterpoint such as particularly FPC reinforcement, gum.

Background technology

When auxilliary materials such as flexible print circuit board stiffening plate, gum carry out the monolithic applying, there is the control of applying misalignment tolerances.In order to control the margin of tolerance of the back according with process requirements of fitting; The process unit that has adopts special-purpose supporting with the positioning control instrument of fitting; And because production unit can be processed Different products simultaneously; Then need be directed against this instrument of each product customization, cause auxilliary material utilance to reduce, strengthen course of processing material cost.

Summary of the invention

The utility model purpose is to propose to need not to adopt specific purpose tool, can effectively controls the FPC of monolithic applying tolerance again.

The utility model comprises the Copper Foil plate body, in said Copper Foil plate body etching paster standard pairs of bit line, in the both sides of said paster standard pairs of bit line difference etching paster plus tolerance pairs of bit line and negative common difference pairs of bit line.

When carrying out the monolithic applying; Each paster is fitted in respectively between each group paster plus tolerance pairs of bit line and the negative common difference pairs of bit line; Can control effectively, easily in the margin of tolerance that each paster falls within the Chip Area; The utility model not only can be exempted the auxilliary material utilance of cost, lifting of making specialized tool, can also improve auxilliary material machining accuracy minimizing simultaneously and squint.

In order to prevent that the paster direction from making a mistake, the utility model is etching paster direction guide markings line on said Copper Foil plate body also.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model.

Embodiment

As shown in Figure 1, etching has paster standard pairs of bit line 2 on Copper Foil plate body 1, respectively symmetrical etching paster plus tolerance pairs of bit line 3 and negative common difference pairs of bit line 4 in the upper and lower both sides of paster standard pairs of bit line 2.And on Copper Foil plate body 1 etching paster direction guide markings line 5.

Claims (2)

1. have the FPC of convenient auxilliary material applying contraposition, comprise the Copper Foil plate body,, it is characterized in that: in the both sides of said paster standard pairs of bit line difference etching paster plus tolerance pairs of bit line and negative common difference pairs of bit line in said Copper Foil plate body etching paster standard pairs of bit line.

2. according to the said FPC of claim 1, it is characterized in that: etching paster direction guide markings line on said Copper Foil plate body with convenient auxilliary material applying contraposition.
