Abstract

A simplified methodology is developed for thermal analysis and design of printed circuit boards. It combines the use of computer-aided thermal network modeling and a simplified experimental technique. In order to demonstrate its capabilities, this methodology is implemented to correlate natural convection on a printed circuit board oriented horizontally inside an enclosure. The empirical constants used in the correlation were determined through a numerical algorithm in which the sum of the squared error between calculated temperatures and experimental measurements is minimized using the downhill simplex algorithm.
