Description

[0001] This application belongs to the field of FPC module test protection, and specifically relates to a protection design device in testing. Background Technology

[0002] With the rapid development of the electronics and information industry, the demand for flexible printed circuit boards (FPCs) for various smart terminals, automotive electronics, and industrial control equipment is increasing rapidly. Due to its characteristics of being thin, flexible, and having high wiring density, FPC has become a core component of high-density electronic assembly. Its quality directly affects the performance and reliability of terminal equipment. In order to ensure that FPC meets the electrical performance, connection stability and other indicators before mass production, it is necessary to conduct strict testing through professional equipment. The testing process has become a key link in the quality control of the electronics manufacturing industry, and the requirements for testing efficiency, safety and accuracy are constantly increasing.

[0003] Current technology is insufficient.

[0004] 1) Existing testing devices mostly use rigid designs for fixing the testing machine, which are only compatible with specific size equipment and have poor versatility. When facing different models of testing machines, the device needs to be changed frequently, which increases the equipment cost and operational complexity.

[0005] 2) The insulation protection measures are simple, mostly relying on a single insulation material, which makes it difficult to completely avoid electrical breakdown of FPC wires caused by test voltage fluctuations. In addition, there is a lack of rigid protection for the connectors, which makes the wires easy to fall off or be damaged due to external collisions or accidental contact.

[0006] 3) The alignment of FPC connectors and test interfaces relies on manual operation and lacks auxiliary positioning structures. This can easily lead to poor contact due to alignment deviations, which not only affects the accuracy of test data but also reduces the lifespan of the wires and interfaces due to repeated plugging and unplugging, thus dragging down test efficiency.
