Good morning to all, We are experiencing difficulties with two particular components. One is a surface mount voltage regulator (7805) and the other is a thru-hole double diode (MBR20100 in a To-220 package). Is it possible that these components are sensitive to static, explaining why the problem is isolated to these components or could it be the thermal profile of the wave that would affect these particular parts? We have never come across this type of problem before. I am perplexed because if our process was at cause, wouldn't more components be affected?
