Bob, what alloy is leading the pack for sn-pb replacement. Will this alloy adapt itself to component leads? What circuit board finishes will we be dealing with?

Tin/silver/copper is the alloy I have done most with and it would seem that it will be the alloy of choice if you look at the people doing the work. There are still some issues of fillet lifting which I have seen on PIHR soldering and the same in wav

Hi Joe, Try: S03X7C-56M from koki - http://www.ko-ki.co.jp which has cobalt in it to extend tip life or: SN100C from Nihon Superior, which is a nickel stabilised alloy that also extends tip life. The Koki solder flows better that any other leadfr

To all smt neters, In many different threads I have tried to bring awareness of the dangers lead free alloys pose to the reliability of solder connections. Many times those warnings have been waved by unscientific reports (from lead free solder manu

I AM JUST EVALUATION LEAD FREE EVALUATION AND FOUND THE BIG PROBLEM OF SOLDER CRACK BETWEEN TERMINAL OF COMPONENT AND THE INTERMETALLIC LAYER OF LEAD FREE ALLOY BUT DON'T FIND ANY CRACK BETWEEN SOLDER AND SURFACE OF PCB , COULD YOU HELP ME VERIFY T

I have the ability to offer both SAC and SN100C lead free alloys to my customer base. What might occur if a customer is already using SAC305 in their wave and they want to save money and go to SN100C. They now are mixing, tin,silver,copper with tin,c

Bet your using tin/ lead plated components with a lead free Cu/Ag/Sn alloy. It leads to intermetallic cracking. Wow didn't anyone tell you to check the archives yet, It seems to be the answer given to everyone. Why have an interactive site if you alw

with lead-free solders, one would expect to find less instances of tombstoning. this is because SAC alloys are not eutectic and melt over a range of temp (usually 217-220 deg C) instead of at a single temperature. therefore the forces due to solder s

Every problem faced with (all) lead free alloys can be solved with 2 words �add lead� I'll keep it short don't want to sound like a broken record.

JBC is offering "Lead free" tips now. They have this on the web site: "JBC recently released a new series of tips featuring a thicker iron bath that we find more resistent to aggressive additives and flux as found in lead free alloy." We have not d
