If I use convective heating in the real process, should I use it in the warpage measurement?
The Akrometrix approach is to try to duplicate the effects of the heating/cooling cycle we are trying to simulate (including heating rates and uniformity), not the causes. As a practical matter, the behavior of a single chamber convective oven is very different from a convective reflow belt oven, so focusing exclusively on the mechanism of heating can be misleading.
