The IPC-610 class II spec is very reasonable. If they expect class 3 then make them pay for it....IMO

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

Pd takes longer to desolve than the materials yer used to using. Search the fine SMTnet Archives for background on modifying your reflow recipe.
