Sulfur is probably the culprit. Board supplier should be providing boards with anti-tarnish sheets between the individual boards. Also, cardboard is a major source of sulfur and so boards should not be shipped in cardboard.

Hi! Does any one can give the reason of the black dust into de wave solder machine. We can found no reason for that, but the machine get dirty to fast despite the maintenance. Thanks for your time Bruna Neto

That's just dross. If you have nitrogen blowing over the wave, you could reduce its flow as it tends to blow the dust everywhere if it is set too high. (on the other hand it might reduce solder quality)

If you use a conventional toaster made for bread, youll have to turn it on its side. Most parts stay on in the up right position but when it pops up they all fall off cause the sodder is still flexable. My customer wasn't to happy about that.

i acutally meant to bake components that are moisture sensitive before placing them. i just want to use a toaster (not the pop up kind), maybe the best way is to just get an oven thermomoter and see where the 125c setting would be on the toaster.
