A compact model or thermal resistor network of a 72-pins polymer stud grid
array (PSGA) assembly is presented. A general thermal network is simplified
to a compact model with seven resistors. Secondly, the effect of the chip
dimensions on the different thermal resistors is investigated. Thirdly, the
compact models are synthesized in a response surface model (RSM). Any cust
omer can then calculate the compact model for his specific application by f
illing in the geometry properties of the package in the RSM-equations and c
alculating the maximal temperature in the assembly. (C) 2001 Elsevier Scien
