Question: A 1 0 - layer PCB board ( with alternating copper and epoxy layers ) experiences an uneven heat distribution during operation. The copper layers

A 10-layer PCB board (with alternating copper and epoxy layers) experiences an uneven heat distribution during operation. The copper layers are each 35m thick, and epoxy layers are 75m. The board operates in a temperature range of 20C to 110C. Calculate the total warping displacement of the board if the coefficient of thermal expansion (CTE) for copper is 16.510-6C. Assume a 2-meter board length and consider the effect of both expansion and contraction cycles.
