No cell phones on the floor under penalty of suspension or worse. They are allowed emergency phone calls as many of the women in production have kids in day-care or school. But the dept. supervisor is the one answering the phone and decides to take a

http://www.mgchemicals.com/products/832.html Loctite makes a version too, if I recall. Designed to be tamper evident, but yes, rework is a bear. We had similar results using one of Lord Chemical's urethane potting compounds. It was a filled black fi

IPA is a poor choice for a cleaning solvent. * As you mentioned, the flash point of IPA (~12�C TCC). This is sufficiently low that all electrical equipment within a few feet of the bath should be flameproofed or intrinsically safe, if you don't want

Mat, Are you sure you should be using SnPb HASL boards if you are doing prep for lead free? If you aren't actually going to comply with RoHS then fire away. Nearly all of our assemblies are now ENIG and as any re-design comes up on a HASL board it is
