Subject: Reliability of Flexible PCB
Message:
Thermal shock test was performed on a batch of flexible PCBs. After the test, waviness was observed at the PCB edges and at areas where there is no copper. Circuit continuity was maintained. However, will the waviness pose a long term reliability problem? Is it a sign of delamination? Appreciate advice/comments. Thank you and regards.
