hello,
at work we use SAC305. it never bothered me in any way before. one day, for some reason, i wanted to know more about different alloys, fluxes, why there is silver or other things, so i started to "google" things, and eventually found SN100C.
I read only good things on it (some on this forum too), how good it flows, wetting properties, overall better than SAC305 in every way. So i told my boss about it, he ordered it, and it came. Then i tryed it.
Result was.. meh.. i mean, it was bad, very bad, it felt like using pure tin without flux, hard to work with, creates big blobs of solder, it hardly flows.
i have few years of soldering experience, mostly with SAC305, and, for me, Its easy to work with. I use leaded solder only for wires.
manufacturer is STANNOL, SN100C Kristall400 2,2%
https://www.tme.eu/sk/en/details/sn100k400_0.7_0.5/solder-wires-lead-free/stannol/810913/maybe the problem is flux? i can get it with kristall511, 2,7%
id like to ask if someone is hand soldering with sn100c alloy?
