Since the wrong temperature can be our worst nightmare, I would do a temp test starting with the lowest and increasing until I had the proper temp to do the job. I have always done this when there is no temp documented to go by. The proper size tip is also very important.

No, an optimized time-temperature profile depends on many factors, the solder paste formula, the board laminate, the components on the assembly . . . -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Richard D. Krug Sent: Friday, September 21, 2012 8:35 AM To: [log in to unmask] Subject: [TN] IPC Standard Temperature Profile for RoHS Pb Free Solder (Hand Soldering)? A customer has asked whether IPC has a standard temperature profile for RoHS Pb-Free hand soldering. I'm not aware of one and since there are multiple RoHS compliant alloys I don't know whether there should or could be one. Is there any such document or series of documents?
