SAC305 has a liquidous state temperature 217 degC. Check the datasheet to compare to this temp. I suppose, it may be lower. - Cheers !

Yes you can use no-lead parts in a leaded process. Your solder joints will be weaker than they once were unless you change your solder paste. You can try to improve this by running a hotter reflow temp, but be careful since your flux was not design

Guys I have a question since the ever present problem with the crack switch we had to change to a low temp lead free solder paste in these case eutectic 58Bi/42Sn and 57Bi/42Sn/1Ag alloys, now the main question whats diferent between these one and th

I agree with Chris. Not all but SOME components definitely had to change to be able to withstand higher heat. I would watch out for some plastic connectors, possibly some active components, and definitely many electrolytic caps. Older stock compone

I agree that it would be crazy to think that every part a company manufactured had to be re-engineered to allow for higher temps. Out of the question and I NEVER implied that at all. What I said was that Zarrow told us that it was alright to use lea

Phil is wrong. In the real world, we know that part mfgers have not changed every one of their parts to make them "high temp". They just changed the plating. Anyone who thinks otherwise, has never run a profile or touched a warm board coming out o

Let's talk pin holes and blow holes. I've been here since the transistion of leaded to lead-free process started for our company and we purchased a wave machine just to keep up with our lead-free orders. we put out 500-1000 boards a day both leaded a

How are Component manufactuers addressing the PB free solder inititive? Since I am told higher processing Temps will be required to reflow the pb-free alloy.

I see, maybe changing my peak temp in reflow will help. I'll try do eval again... Actually, once I did have evaluated a longer pre-heat but on my previous eval, I didn't change the peak temp. Maybe reflow can help compensate to my problem in the part

You can most certainly use the same reflow oven for both leaded and lead-free pastes. Obviously your thermal profiles will be different, as the lead-free paste should have a higher reflow temp. As long as your oven has adequate exhaust and flux manag
