Abstract

This paper concerns thermal analysis of the IC package board. To analyze fundamental mechanisms of fluid flow and heat of the IC board array, the IR radiometer is used to visualize radiation temperature pattern of the IC package surface through a transparent plastic wall. Considering transmission rate of the plastic wall, the measured radiation temperature was transformed into the real temperature as function of the emissivity of the IC surface. Isotherm of the radiation temperature distribution of the front and back side surface of the IC board shows the existence of thermal wake pattern caused by surrounding air flow. Steady state and transient 2D temperature distribution of the IC package, heat transfer rate of the front and back side of the IC board and cooling enhancement effects were measured and analyzed systematically.
