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.

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.

SN100C is being used by 95% of our customers over the SAC305. The main reasons are Cost big savings easily $10.00 lb, nice shiny solder joints good for quality inspection. Very few people are using SN100C in SMT Due to increased temperature requireme

We are using SN100C in both our wave and selective machines and have very good results. We also using it for ROHS hand soldering. It flows better than SAC305, the joints are shinny just like Sn63/37. We are looking into using SN100C as our paste b

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

We started with SN100C from the very beginning when we purchased our selective solder machine. It has been working well for us. I can't speak to what happens when changing over to it, but I've heard of many companies using SN100C for selective sold

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
