We have tested SN100C and SAC305 in our selective solder machine (Ersa Versaflow). We wanted to test both alloys in the selective first because the investment in filling the pots is minimal. In our initial tests the SN100C alloy appears to be the bes

CMiller, Thanks for the valuable info! We are in the midst of lead-free deployment and need to know good alloy choices at both wave and ERSA. I have heard the same things regarding SAC305's price for bar solder, but don't yet know what the process

We have been seeing continued difficulty with solder shorts and/or insufficient barrel fill with our Juki selective solder machine while using SAC305. We want to switch to something in the SN100 series, but we do not know enough to seperate the hype

I will try with temperature 255 C degrees. The wetting force vs. solder temperature for SAC305 is more than 265 C degrees (the temperature of trials). Thanks for the advise. Regards

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?

Hi Marcus, by using SN100C have you seen any tearing phenomena like what shown on the link ? http://www.smartgroup.org/pdf/Defect01.pdf Tnks Regards.........GS

No I have seen Zero hot tears. Thats with water soluble or No-Clean. We have built over 10,000 boards.
