can any one tell me if you should run the same heat on the same boards no matter what deffrent parts are on the board Should you do a oven profile for every deffrent board or is it the thickness of the board that matters.

Hi Yes I agree, yet this subject is about Tombstoning and oven profile or even oven working correctly across the entire product is a sub-set of how one gets those little chip babies to sit and stay where they belong. Flat and Heeling like their mast

Just to be sure, you really should. PCB thickness and component density are the key players.
