Description of Model using in simulation The model used in this simulation consists of a wind tunnel which encompasses the whole computational domain with a motherboard and several 84 lead PLCC on top of the motherboard but not attached on it.
The isometric view, plan view, and front view of the simulation setup for 4 PLCC packages are shown in Figure 1.
A combined model is combination between PLCC packages and motherboard that have been used during the simulation.
It is tolerable as slight difference in shape may not affect the simulation result.
