Paper Abstract

A protocol for infrared thermal analysis of die surfaces is proposed. The most suitable infrared camera has a spectral response in the 8 - 10 micrometer of the infrared spectrum as the emissivity is higher and more uniform across the surface of the die than in the 3 - 5 micrometer region of the spectrum. Through the prudent use of shielding, die surface temperatures can be measured, thermal gradients are detected, the effectiveness of cooling lines can be evaluated and spray patterns are optimized. The technique is not suitable for examining aluminum parts as the emissivity of aluminum is low and the optical properties of the surface oxide layer change as the part cools.
