Subject: PCB residue after wave solder
We recently started to use wave-soldering. As total newbies in that field, we got successful results most of the time. Howewer, this batch of PCB's had a lot of resdiue, as shown on the picture. Most of it is most likely flux, but on some areas even some soldering alloy is visible (marked red on the picture). It's a leaded soldering wave with foam fluxer and IR pre-heat. Any suggestions will be helpful. Also, if someone knows a good on-line tutorial on wave soldering (how-to's, do's and dont's) I would appreciate a link to it.
