Slaine, our intuition is the same as yours [that 100Sn should dissolve the copper faster than other solders]. Bob Gilbert's FCT data shows otherwise. Look here: http://www.fctassembly.com/newsltr/2004/0804/Aug04.htm

It is true that the SAC alloys are very aggressive to unprotected solder pots but the SN100C lead free alloy can be used in these pots IF they are not already being wetted by your SN63 alloy. FCT Assembly offers a program that includes free tin wash

Hello Arnold, Yes, by definition of joint formation, copper will dissolve in lead free solder in order to form the connecting intermetallic layer. There is a distinct difference in the copper dissolution rates of the major alloys being considered wi

Hello Greg, I agree with you that the article in SMT Magazine should be studied very carefully as it contains many errors in respect to SN100C. The testing performed was a DOE and was not an optimized run. There is also a statement on dross generatio

Hello Greg, Glad to hear your success with the SACX0307 copy. By the way, does the P mean it contains phosphorus? Does yours also contain bismuth like the SACX0307 (according to their plumbing solder patent for X0307)? In response to your discussion
