This can be an extremely involved subject but to get the basics I
recommend that you refer to IPC J-STD-004 "Requirements for Soldering
Fluxes", section 3.2.7.1, which will reference IPC TM-650, Method
2.4.46.  This should provide you with a quick synopsis.

Subject: [TN] basic info on soldering


Hi all,
I am working on different finishes for "lead free" applications
.Recently I got results of solderability tests as graphs showing
"wetting force vs time" and "contact wetting angle vs time" , but I do
not know how to interpretate it. I would appreciate basic info on this
stuff. thanks Edward
