Hi all,

If you are profiling a pcb that has a wide variety of comonpenents with varying temperature sensitivity requirements what do you do?

e.g. 1136 ball BGA with min reflow temp 245 with tsop48 with max reflow temp 235 etc.

Without knowing your board, oven or profile, I would suggest working the middle of your profile. Try a slower conveyor speed to increase your soak zone of your profile. This will decrease your delta-T across the board. You may also have to work on your reflow zone(s) a little as well. But start with your soak first and measure results.
