An optical module testing device

Abstract

The invention discloses an optical module testing device which comprises a PCB (printed circuit board), a to-be-tested optical module and an optical fiber patch cord. A flexible circuit board is disposed on the to-be-tested optical module. In a testing state, the optical fiber patch cord is connected with the to-be-tested optical module, the flexible circuit board of the to-be-tested optical module is electrically connected with the PCB which is disposed on a bottom plate, a patch cord inserting seat is disposed on the bottom plate, a module mounting hole is formed between the patch cord inserting seat and the bottom plate, a patch cord inserting hole is formed above the module mounting hole, and when the optical fiber patch core is inserted into the patch core inserting hole, the optical fiber patch core is electrically connected with the to-be-tested optical module disposed in the module mounting hole. The optical module testing device has the advantages that a pressure head is connected through a rotary shaft and a pressing plate, the testing device is simple in structure and good in structural stability during testing, mounting and demounting of each part are convenient, and repeated testing by using different PCBs, different to-be-tested modules, and the like is facilitated.

Description

technical field [0001] The invention relates to the field of FPC testing of flexible circuit boards, in particular to an optical module testing device. Background technique [0002] Flexible printed circuit board (Flexible Printed Circuit Board), also known as "soft board", is a printed circuit made of flexible insulating substrates. It has many advantages that rigid printed circuit boards do not have. For example, it can be bent, wound, and folded freely. The spatial layout requires arbitrary arrangement, and arbitrary movement and expansion in three-dimensional space, so as to achieve the integration of component assembly and wire connection. [0003] After the flexible circuit board is produced, it is necessary to test the corresponding points, and judge whether the flexible circuit board is good or bad by the size of the resistance. parameters to test.

Problems solved by technology

[0004] Existing test tooling usually uses welding to weld the flexible circuit board on the test platform for testing. As the circuit distribution on the flexible circuit board is getting denser and the test points are getting smaller and smaller, the existing The traditional probe test method is slow, difficult to test repeatedly, and the test accuracy is low and the precision is poor, especially reflected in the difficulty of controlling and adjusting the test pressure, which seriously affects the accuracy and efficiency of the test
