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

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?

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

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

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.

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.

Hi Chris! I hope this will help you! The CBGA uses an array of high melting point solder spheres(Sn10/Pb90) to connect its ceramic chip carrier to an epoxy glass (FR4) PCB using eutectic (Sn63/Pb37) solder joints at both ceramic and card inter

Continuing along the path that Brian took ... IPC-7525 gives design guideline for stepped stencils. It goes something like: * Stepped area SB GT 25 thou from pads located on the greatest thickness of the stencil * Pads in stepped area SB GT 35 tho
