PCB board-level process quality evaluation

Short Description:

In mature automotive electronics suppliers, process-related quality issues account for 80% of overall problems. Abnormal process quality can lead to product failures, disrupt the entire system, and result in large-scale recalls, causing significant financial losses for manufacturers. In some cases, it even poses a safety risk to passengers.

With over 10 years of experience in failure analysis, GRGT offers automotive and electronic PCB board-level process quality evaluations, including VW80000 and ES90000 series. This expertise helps enterprises identify potential quality defects and better manage product quality risks.
