Hey Brian, Did you use the auto profile feature on your DRS25 machine to arrive at your profile? Our DRS25 has been doing quite well at larger BGA components. Most critical is a good preheat until the PCB reaches at least 140c, followed by a 2degC

Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar
