Hi Victor. In general it's one of the three: poor board quality; moisture in the board or thermal abuse.

Subject: [TN] PWB laminate delamination

Fellow TechNetters:

Where can I find information regarding delamination? Are the laminate material separation artifact of thermal excursion, solder float test, 3x or 6x, differ from that of an exothermic event in which current/heat melts the laminate and/or heat exploded/cracking the laminate.

Victor,
