I need some advice on how to run a test with some large boards through the re-flow oven. The boards are 17"x17", 3/16" thick. Withought destroying one of the boards, how would I go about getting a good temperature profile?

Doug, If you are worried about cooking the board. Take a know profile and either reduce the heat in each zone or increase the belt speed.This should keep you from cooking the board. then adjust the profilr to the board from there.
