MA/NY DDave, I'll take your money. I'm betting on the Class II, whatever that is, because: * Solder is the same. * Board is the same from a fabrication and probably materials standpoint. * Components are the same. * Processing is the same. ... but

Has anyone seen or put together a good collection of proper handling procedures for components and PCB's? I realize a lot of it is no-brainer stuff, but I need some depth for a training class we are putting together. This would include ESD, Moisture

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate
