Wave flux and profiling

Electronics Forum | Wed Dec 20 04:43:36 EST 2006 | greg york

Any decent flux would volatise off with the heat of the wave unless absorbed into the solder mask. Test this by trying to clean in alcohol or common solvent aerosol, if it does not clean then it is probably Mineral Salts from solder mask fillers. Ano

ESD Smocks and chairs

Ecofree 303 conductive and corrosive?

Electronics Forum | Mon Aug 24 06:12:31 EDT 2009 | ghepo

joanne please pay attention, each heavy no-clean flux residues not completely heated due to hand soldering becomes a moisture absorbing conductive pathway, causing electrical leakage. So I suggest you to clean well the board after hand soldering or
