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

Only at our selective solder process.

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

I would like to know what you are seeing in production. I have read the papers that state fewer tombstones with SAC305 as well as the papers that state more tombstones with SAC305. I am seeing more tombstones with SAC305. I place a lot of 0402 com

Yes, we added some soak, we also use a 5 zone oven. We utilize a .020" x .020" pad with center to center at .042". We only get tombstones on misplacement or bad paste release now. Registration of component is key with pbfree, the parts just don't s

Russ, By a longer profile you mean a more even slope across the entire profile. Unfortunately I only have a 5 zone oven that is fairly short. How many heated zones are you using? Did you shrink the 0402 pad design and leave less pad exposed out a

Hi Paul, not to throw a wrench in here but I beleive that paople are talking about switching from SAC in wave to SN100C, NOT SACx, these are different. and should not be confused. SACx is supposed to fall somewhere in the middle of the SN100C and t

Hello, tried searching the SMTnet archives, but not yet a clear answer - maybe there is not a one yet ? ;) last discussion I found is few years old so maybe there is a fresh view on that? Q: we want to prove that our proces is "clean" we use SAC30

Is there anybody out there doing this scenario: SAC 305 Reflow & SN100C Wave and Selective Can the 2 alloys be mixed on 1 board, say, SAC 305 for SMT, and SN100C for thru-hole? Are 2 different rework chemistries needed, or can one use SN100c wire

280 is pretty hot dont you think have you tried the alloy at 260-265 where SAC 305 works ? Thx
