I would run the passive side first just because the BGA is probably moisture sensitive and I wouldn't want to have to keep track of the time between first and second reflow.

Have you checked your reflow profile? You need top make sure that you are with the specification of the solder paste. We currntly use the Kic thermal profiling device.

Bother are valid choices, Rehm is better made(stainless steel tunnel, lower power usage, threepahes blowers etc) If can afford it would be better choice. From experience Hellers Specs are a bit flaky... But they both will solder PCBs.

maybe the pcbs need a proper dry (the quick dry in the reflow oven won't get all the moisture out )...maybe 125 C for 4 hours or speak to the manufacturer to get their recommendations.

70k and that is not so bad for a new machine? They feeders are pnematic... But I'm guessing I cant start driving a Ferrari as my first car, but start up with a low prised Hyndai and work my way upwards;)
