Sure. Treat it like wave solder. Top side wetting is generaly harder to achieve than wave so don't over look it. On most selective solder machine, the delta-T is also something to look out for. Most move from preheat to pot. And snce the pot por

It looks like the 330 Convection & the GF120 ovens would really stuggle to do lead free, with 3 zones (the 330 has 3 top, 1 bottom). Can't comment on the 545 oven, you'll have to get them to run profiles with a selection of your boards & check on
