I am currently venturing into the world of pcb metallic finishes. I have acquired some pcb's with immersion gold on them and have met with what seems to be limited success. I was wondering if there are any tricks of the trade for processing these style boards thru a conventional SMT/Wave solder process? If a different formulation other than 63/37 solder paste is recommended? and who it stacks up to the OSP coatings? Stephen Weldon Manufacturing Engineer Diagnostic Instrument Co.
