suggestion: solder + flux
« on: February 07, 2018, 03:49:19 am »
Explaining different solder types, flux, temperature, metal compatibility etc.
I love Kester products but they have 24 different wire solders alone :-//
For noobs it's overwhelming.

IPA attacks the soldermask on my chinese PCB's, so using rosin-flux solder not a good idea.
No-clean residue not so good with moisture for leakage current.
I touched lead solder, am I going to die? Or just be crazier than usual and post weirdness...

Water-soluble flux is an option if you can't use solvents or tolerate no-clean flux residues. Keep in mind, though, that it must be promptly removed, as it's very corrosive. Lead solder isn't terribly dangerous if you wash your hands after handling it.

As far as rosin fluxes go, I like Kester 44. It's active enough to tin corroded surfaces, has an OK smell, and can usually be treated as a no-clean flux (at least for hobby projects).

Another vote for Kester 44 (63/37).  :-+

As it's flux is RA, it's good for repairs and NOS components as it can cut through any oxidation. FWIW, CML Supply breaks down liquid fluxes (186, 1544, 951, 959T) as well as Easy Paste 256.
