As a distributor we sell very little SN100C for SMT, we sell far more SAC305 for SMT. The higher temperatures are the reasons.

We are not using SN100C in our reflow process but I know the type of flux made a big difference with our SAC305 solder. We started out using no-clean flux in our SAC305 paste and were having some issues. We then switched over to a water soluble flu

I'm testing SN100C, and with our 5 zone oven I seem to be able to fix one issue by changing the profile, but that might introduce a new problem. Some profiles work very well on most components, but have issues on other components. These are usually 0

This make me curious how many people are using sn100 versus how many using sac305. The sn100 seemed to generally cover the pads and flow a little better, and looked nicer, but SAC305 overall was easier. Is this normal or do I need to work more on sa

Hello, I produce two types of board. - 100% Thru Hole - 50% thru hole and 50% SMT For the second, I have a bad wetting after the reflow on the top. The pcb board have Au-Ni pad. I use a water soluble paste. I clean the board with a solution with

Before anyone tells me to search the fine archives, I already did! I typed Sn100c and Reflow, and nothing came up. Anyway, any of your folks out there run Sn100C across the board - Reflow, Wave and/or Selective, and Hand-Soldering? If so, please p

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

We have using SAC305 type solder paste for lead free process. One sample paste received of SN100C.After reflow SN100C type paste joint looks brighter and good compare to SAC305. Please help me which paste is good for smt process?

Just wondering what the companies that are use SN100C are using for reflow (I guess SAC), and especially for handsoldering. Do SAC and SN100C mix? are there any studies proving this?

I guess the paste is Leaded hence the 220 Peak temp and the Sn100c is Eutectic at 227C so you need to be hotter to melt the HASL finish or you are relying on it alloying together with the paste which takes much longer. suggest running peak temp of 23
