My Company has 3 XPM2 Vitronics reflow ovens, one new in 06, one new in 08 and one new in 10. They have all been relatively trouble free over the last 6 years, however recently I'm seeing a white powdery substance on my filters, for the two oldest(s

We have Heller, 1707EXL now. It has a removable support for the mesh conveyor that just pull out (clipped in). Had an Electrovert and they were bolted on and very tuff to change out. The oilers Im not sure I care for though,they have a metal rail t

Has anyone experienced bridging on topside (solder destination side) surface mount devices after wave soldering? We x-rayed 100% of the placements after smt re-flow with no issues. When the same placements were x-rayed after the tht wave solder pro

This has been a challenge for most manufacturers. It depends on board thickness, lead or lead free paste/parts. We have a slim-kic to get the profiles correct in our 14 zone oven. I believe it may be the recently posted suggestion of too much heat in

We're having problems with Kester pastes (NP545 pb free and EP265 60/40 no clean pastes.) All of our other components reflow just fine with either paste, but for some reason this QFN chip doesn't wick to the QFN's pads well. It seems like some type

Probably to late for ya, but: -Center support -mesh belt and conveyor (have the mesh is nice for 1st side runs to keep the board flat. -N2 capable, in case you need it -on board profiling -smema if needed -board drop detect (sensor at input and exit)

I've seen them down at 2 metres in the past, but usually only 4 zone. from memory Electrovert used to do a small 5 zone with pin chain - Infraflow 500 or something. To be fair, even small one line CEMs usually have a decent oven as you need to be a

Hi , thanks.. yes you are right.Its bot and top side. Decreasing the lower heaters and increasing the top heaters for secondary side. will this matter in convection reflow ovens. Since the heat at the end will get equally distributed. We were s
