We use 125 W/m^2*K on the top and 60 W/m^2*K on the bottom for microhotplates from "Thermal Management of Micro-Hotplates using MEMCAD as Simulation Tool", D. Briand, M.-A. Gr"tillat, B. van der Schoot and N.F. de Rooij, I think the publication date was 2000 but don't have the rest of the reference. -Mike >>> philippe_helin@hotmail.com 08/09/02 01:05AM >>> Hi, I am looking for value of convection coefficient between silicon and air for thermal modeling, any idea ?
