I don't believe you are missing anything, Amol. Mainly, you just need to make sure that your oven handles the higher temperatures needed for reflow. Also, there has been a lot of discussion on how many zones are needed to properly reflow lead-free

Mike You get what you ask for. We ask for 0.001 inch minimum. If your supplier's published process range allows thickness below 0.001 inch minimum, you need to define your own acceptance criterion. We don't use average measurements in lot inspect

Yea we had A LOT of issues during the first couple of years with ours. I think we've replaced all the motors. It basically does sketchy things all the time. Never know what to expect with it. Since the first 2 or so years it has been somewhat stable
