 		 #116078 - none, I can see no cause but "dissolved
Responding to: ???'s previous message
Can you see any other indications of mishandling, maybe that, what a sharp knife makes, when it touches the PCB?

none, I can see no cause but "dissolved glue"

Erik

PS Of course "glue" refer to whatever hold the two together (cold weld, weld or whatever).
