Be sure to peel the potatoes. I saw a guy use a potato to purify gold on the TV show Rough Science. Seriously though I would think SAC305 to SN100C wouldn't be as bad as eutectic to leadfree.

We were using AIM WS485 SAC305 and AIM NC257 SAC305 and we had problems with voiding and AIM�s narrow process windows. Now we are using Indium3.2 and Indium8.9 with much better results.

My customer wants an SnPb 63/37 BGA soldered using SAC305 solder paste. What data is avaiable showing the long term reliability of the intermetallics of the solder joints?

First, make sure that 63/37 BGA can withstand higher reflow temperature of of lead free SAC305 GSx

We are thinking of switching over from sac305 to sn100. Has anyone had any experience with this changeover and is there any drawbacks to switching to sn100?

I'd say it depends on the whole process you have. With our 5 zone oven, I could never get a profile that worked as well as SAC305, so we switched back.

Actually we were looking into it for our selective solder process only. We are pretty happy with the results of 305 at smt.

kkay: I'm not real clear on where in the assembly process flow that you are considering replacing SAC305 with SN100. Please clarify

Thank you Djo for your sharing. By the way, do you know that which field/product will prefer to use SAC405 paste instead of SAC305 or lower Ag wt% alloy solder paste?

From what I understand SAC305 and SAC405 are considered low silver content and have the better overall mechanical qualities compared to more silver or no silver.
