Hi All, Quite often, I encountered Solithane coating dewetting issue over some IC moulding (rough or smooth, did not trace what moulding material is used) compounds across different suppliers, though the whole PCBAs are being cleaned with EnSolv. What is the cause of the issue? Is the cause due to the release agent used during the moulding compound process (but why cannot be clean away)? Thank in advance!
