Abstract :
The MQUAD microelectronic package was developed to provide a high level of thermal performance for high leadcount integrated circuits.1 A numerical, lumped-parameter transient thermal model has been developed which accurately predicts the temperature of the die and other components of an MQUAD package in situations in which the power to the die changes. Examples of such situations are the power-up and power-down cycles and power excursions. The model is used to predict the behavior of a 160 lead, cavity-down MQUAD package in these situations under conditions of low and high circuit board conductivity and natural and forced convection. The predictions of the model are shown to be in good agreement with experimental values for representative situations
