Abstract

The utility model relates to a micro connection structure for a flexible circuit board, a plurality of single flexible circuit boards are arranged on an integral board together, at least two micro connection points are arranged on each single flexible circuit board, and the single flexible circuit boards are connected with the integral board through the micro connection points with no external force application. The micro connection structure has the advantages that: the cutting and inspection speed of products are improved, the integral inspection is carried out by the operator without the inspection piece by piece so that the productivity is improved; when the micro structure is adopted by customers, mechanical equipment is used for assembling components, and after assembly, the product can be removed from the integral board through slight force applied on the micro connection points for other assemblies; and the use efficiency is also improved.

Description

Little syndeton of flexible circuit board

Technical field

The utility model belongs to the printed circuit technique field, is the flexible circuitry plate technique, relates in particular to a kind of little syndeton of flexible circuit board.

Background technology

Flexible circuit board (Flexibility Printed Circuit is called for short FPC), with respect to rigid circuit board, soft board material characteristic is a pliability, and have advantages such as easy turnover, in light weight, thin thickness, therefore need often to be applied to the product of thin design or movable mechanism design, as mobile phone, mobile computer, display, consumption electronic products, contact panel and IC structure dress etc.Attaching the back pressing by flexible copper foil substrate (FCCL) and soft insulating barrier (polyimides (PI) commonly used or PETG (PET)) with solid (glue) on the soft board product configurations forms, and can attach annexes such as stiffening plate or mounted connector according to customer requirement and use and enlarge the scope of business or provide the client than complete service, therefore, from buying raw material such as Copper Foil, flexible copper foil substrate, PI, till the Assembly processing procedure, be roughly category of soft board industry.

The finished product form of FPC is a monolithic, needs during making according to product design the monolithic product to be combined into tens or up to a hundred, and the about 500mm * 300mm of size is to be fit to the batch process of production line; Need to expose, develop through pasting dry film, etching, overlay film compacting or printing are electroplated, and after the operations such as subsides double faced adhesive tape, product are die-cut into monolithic, back check, packing, delivery again.

The mode of production of this monolithic product, the visual inspection of die-cut back need a slice a slice product of taking, and efficient is carried not high; When the client uses, also need a slice a slice product of taking, be unfavorable for the product assembling.

Summary of the invention

The utility model technical issues that need to address are to provide a kind of little syndeton of flexible circuit board, make to keep several little tie points between profile and the whole plate when die-cut, and product can keep whole piece form, rather than the form of monolithic; When the client uses, be beneficial to the assembling of automation, and after assembling, can conveniently product be taken off.

The technical solution adopted in the utility model: most monolithic flexible circuit board are located on the whole plate jointly, on each monolithic flexible circuit board, be provided with and be no less than two little tie points, and the monolithic flexible circuit board when not being subjected to external force and whole plate link into an integrated entity with little tie point.

On the such scheme basis, the width of described little tie point is at 0.6～1.0mm.Concrete width can be 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm.

The beneficial effects of the utility model are:

1, product speed when die-cut and check has improved, and whole piece check makes the operative employee not need small pieces, a little flake products to go to take, and has improved production efficiency;

When 2, the client uses, can use mechanized device assembling components and parts, after assemble, need exert oneself a little, just product can be taken off from whole piece, carry out other assemblings at little tie point place; Improved service efficiency.

Embodiment

See also Fig. 1 for little tie point structural representation of the present utility model and Fig. 2 for shown in the overall structure schematic diagram after die-cut of the present utility model, a kind of little syndeton of flexible circuit board, a most monolithic flexible circuit board 1 are located on the whole plate 2 jointly, and being provided with four width on each monolithic flexible circuit board 1 is the little tie point 11,12 of 0.8mm, 13,14, and monolithic flexible circuit board 1 when not being subjected to external force and whole plate 2 with

little tie point

11,12,13,14 link into an integrated entity.

During designing mould, place several little tie points, width is at 0.8mm; When die-cut, adjust the die-cut degree of depth of mould, be connected on the whole plate in the part of little tie point to guarantee the flexible circuitry panel products, and other parts are die-cut fully.

Claims

1. little syndeton of a flexible circuit board, it is characterized in that: most monolithic flexible circuit board are located on the whole plate jointly, on each monolithic flexible circuit board, be provided with and be no less than two little tie points, and the monolithic flexible circuit board when not being subjected to external force and whole plate link into an integrated entity with little tie point.

2. little syndeton of flexible circuit board according to claim 1, it is characterized in that: the width of described little tie point is at 0.6～1.0mm.
