A flexible board convenient to use and an assembly fixture thereof

Abstract

The invention relates to a flexible board convenient to use and an assembling fixture thereof. The flexible board comprises a flexible board body, A main via region and a standard pad region are arrange on theflexible board body, a group of electrical networks correspond to the electrical networks of optical device pins to be fabricated or tested is arranged in the main via region, and a group ofstandard pads correspond to the electrical networks of the main via are arranged in the standard pad region. The flexible board body further comprises a test pad region, wherein the test pad region isarranged between the main via region and the standard pad region; A set of test pads corresponding to the standard pad electrical network is provided in the test pad area. The invention has the beneficial effects that: by increasing the butt joint tolerance between the circuit board pad and the test pad, the poor butt joint or even misalignment of the flexible board body and the circuit board padis not easy to occur when the test is carried out, so that the reliability and the yield of the optical device in the test process are improved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a flexible flexible board and an assembly fixture thereof which are convenient to use. Background technique [0002] In electronic equipment, in order to constitute its circuit, a flexible soft board called a flexible printed wiring board (Flexible Printed Circuit, FPC) is widely used. A structure in which wiring is formed on a sheet-like base material using a conductive layer such as copper foil. The flexible soft board has a thin thickness and can be bent, flexed and other deformations. Therefore, according to the flexible flexible board, it is possible to arrange the wiring in the gap in the electronic device, or arrange the wiring in the movable part, or arrange the wiring three-dimensionally. [0003] In the case where the flexible soft board is composed of two or more layers, in order to electrically connect different layers, a through hole with a circular c...

AI Technical Summary

Problems solved by technology

[0004] Since the flexibility of multi-layer boards is much lower than that of single-layer boards, in the multi-process production and testing of optoelectronic devices and modules, repeated positioning and assembly will cause damage to flexible boards, which not only affects appearance, but also affects performance, leading to the use of flexible boards. The product must be replaced with a new flexible board at high temperature before it is sold. During the high temperature replacement process, it is easy to cause damage to the product again and cause it to fail.
