Abstract :
This paper summarizes the results of an extensive thermal evaluation of the 28×28 mm plastic QFP PowerQuad2 package. The work was performed using an advanced three dimensional finite element thermal modeling program to characterize the thermal performance. Included in the study is an analysis of the effects on thermal resistance of die size, airflow, power, printed circuit board (PCB) type, PCB size, PCB Effective Heatsink Area (called PEHA), and the number of package leads and bond wires. Data is also presented on the Øj-pcb (junction to PCB) thermal resistance values for various configurations of the package and PCB
