So there you go Mo, just use these products and you can then mix your alloys! I am sorry that i forgot to mention this aspect! Russ

In switching to lead free processing, we find ourselves having over 400 PCB part numbers with Sn63 HASL finish. And there is no hope of quickly purging inventory and getting our drawings changed to call out a lead free finish. I want to avoid having

The surface tension of lead free solder alloys doesn't self align as well as it does with leaded alloys. Taking the guesswork out of alignment would negate the need for expensive split vision systems and make the parts hand reworkable.

Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time

hi we use a no clean solder paste with the sn63pb37 alloy and our high frquency board doesn`t have any problem in test but after this product is finished now we use 2 different solder pastes 1. sn62 pb36 Ag.4 RA tape 2. NC type lead free with Ag i

Hi. Anyone in this forum experienced the lead-free solder paste SAC305 and SAC405? What are the differences to expect for solder paste with SAC305 and SAC405? What is the effect of silver (Ag) alloy in solder paste? It was really appreciated if could

Does it fail to function or does it function outside of acceptable tolerances? If the latter I wouldn't know what to think, but if the former I would feel obligated to suspect solder quality or maybe even a component problem with the elevated lead-

I am curious whether anyone is experiencing AOI issues in transitioning to lead-free solder inspection.

Tuan - One of the reasons I suggested pre-tinning (aside from the negative effects of Gold on appearance and reliability) is the known slower wetting of Sn/Ag and Sn/Cu alloys as compared to Sn/Pb. If you don't have to be Lead-free, the high Lead

Can anyone tell me if there is a volume difference between a pound of lead vs. lead free solder? Does lead free solder attack stainless or castiron when it's not molten? Thanks. Jay
