Hi Patrick, For UP 78 the best profile is also the easiest. Straight ramp to 220-225 1-2 degrees C per second TAL 45-60 seconds drop it staight off The Tech bulletin says the exact same thing. Former Alpha Guy here

IPC-FA-251 recommends 121*C for 30-60 minutes for 1 and 2 flex layer circuits. A rigid flex can take easily an hour per layer depending on the construction.

0805 is 80 thou by 50 thou. As there are 40 thou per mm, this is therefore a device which is 2mm by 1.25mm, i.e., a 2125 Cheers, Colin...

We have used small hi temp labes, that are placed on our panels, boards before reflow. Each operator has a roll of labels with an assigned number. 4 operators, label 1, 2, 3 and 4. It worked well for us.

Brad- Try doing a search of the archives. I'm sure you will pull up many discussions to help you out. The question you pose comes up every 2-3 months it seems....perhaps it's beaten to death. Rick
