| Project Background

As the carrier of various components and the hub of circuit signal transmission, PCB has become the most important and crucial part of electronic information products. The quality and reliability level of PCB determine the quality and reliability of the whole machine equipment. Due to the high-density development trend of PCB and the environmental protection requirements of lead-free and halogen-free, more and more PCBs have various failure problems such as poor wetting, board popping, delamination, CAF, etc. Obtaining the failure mechanism and causes of PCB will be beneficial to the future quality control of PCB, thus avoiding the recurrence of similar problems.

MTT's engineering and technical personnel have many years of experience in the fields of PCB/PCBA quality evaluation, failure analysis, and UL testing, and have accumulated numerous practical cases. They provide different solutions for customers at different stages such as R&D, certification, production, and customer service complaints, enabling customers to quickly solve problems and seize market opportunities.
