I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a

For the lead free reflow process we tested with our Vitronics 500smr oven. To reach the high temperature of the lead free profile was no problem. We are not using an active cooling system so the pcb's are maby to hot wen the leaving the oven. Can an

starting point with zone settings would be, 100 / 160 / 200 / 225 / 260 deg C...but you'll have to check the exact profile on the pcb with a reflow profiler....making sure you meet the paste spec and making sure you don't heat any devices up to quic

Ther is a solder alloy out there that is supposed to allow lead free wave processing without having to upgrade pumps and such or increasing the pot temp (direct drop in). I have not used it nor do I plan on doing leadfree wave soldering but you may

woow, slow down hot rod, hey davef, you are alright by me, good to see some one out there that has hands on experience rather than a theory nut.... any how, you need a top of the line profiler, super gold mole, or Kic.... these truly are the best and
