Todd- We just upped our solder pot temp from 460F to 490F and saw dramatic improvement in topside fillets using selective solder pallet. Our no-clean flux residue was also dramatically reduced. However, the dross formation rate increased accordingly. A trade-off, but the solder quality may be worth it.
