How to improve the reliability of PCB connectors

October 14, 2024

How to improve the reliability of Pcb Connectors starts with the selection and improvement of connector reliability and durability. In addition to electrical interconnection properties such as transmission rate, current and voltage that can be carried, the mechanical properties, electrical integrity, EMI shielding characteristics and termination of the connector should also be given key consideration.

The types of connector failures include delamination, cracking, warping, CAF, etc. Therefore, we cannot ignore the quality and performance of connectors. When selecting connectors, we need to consider their durability, optimising contacts, insulators, locking and termination, sealing and shielding.

Secondly, we need to conduct reliability tests on PCBs, including soldermask hardness test, ionic contamination test, curing test, glass transition temperature and thermal stress test, voltage withstand test, CTE test, exploding board test, green oil dissolution test, lead-free solderability test, impedance test, and hole pulling force test. These tests can help us find and solve the potential problems of PCB and improve its quality and performance.

In addition, we also need to pay attention to the design and manufacturing process of PCB. In the design and manufacturing process, we need to strictly comply with the relevant standards and specifications to ensure the quality and performance of the PCB.

Finally, we need to carry out regular maintenance and repair of PCB. For example, Excellence Xin Electronics Co., Ltd. has 22 years of professional experience in connectors, terminal cables and wiring harnesses, which not only meets the standardised mass production requirements, but also can carry out non-standard processing and customisation. This shows that regular maintenance and upkeep can extend the service life of PCB and improve its reliability.

Overall, to improve the reliability of PCB connectors need to start from a number of aspects, including selecting and improving the reliability and durability of the connector, conducting reliability tests on the PCB, paying attention to the design and manufacturing process of the PCB as well as regular maintenance and repair. Only in this way can we ensure the quality and performance of the PCB, extend its service life and improve its reliability.
