Problem Set #5 Due Thursday May 6 1. Shown below is a diagram of a circuit board with dimensions 14cm x 8 cm, on which are located 16 integrated circuits (IC’s) with cross-sectional dimensions 1cm x 1cm. The circuit board is 1mm thick, has an average conductivity of 165W/mK, and each IC generates heat at a rate of 1.6W that is conducted to the board. The top and bottom edges of the circuit board are maintained at fixed temperatures of 25°C, and the left and right edges are exposed to air, and may be considered insulated. As discussed in lecture, a two-dimensional model of the temperature field in the circuit board can be obtained by averaging over its thickness, in the z-direction. Use such a model with the relaxation method to calculate the temperature distribution in the region 0 x 14cm and 0 y 8cm. Treat the 2 cm 2 cm 2 cm 2 cm 2 cm 2 cm 2 cm 1 cm 2 cm 2 cm 2 cm 1 cm T=25°C T=25°C Insulated
