How to avoid ICD failure in PCB production?
ByGrace July 5, 2025July 7, 2025
ICD failure, i.e. Inner connection defects, is also called inner layer interconnection defect. For PCB manufacturers, ICD problems are difficult to effectively intercept in the electrical testing process, and often flow to the downstream or even the client. During the SMT mounting process, the PCB board undergoes the impact of high-temperature processes such as lead-free…
