System Design Information
When a heat sink is used, the junction temperature is determined from a thermocouple inserted at the
interface between the case of the package and the interface material. A clearance slot or hole is normally
required in the heat sink. Minimizing the size of the clearance is important to minimize the change in
thermal performance caused by removing part of the thermal interface to the heat sink. Because of the
experimental difficulties with this technique, many engineers measure the heat sink temperature and then
back calculate the case temperature using a separate measurement of the thermal resistance of the interface.
From this case temperature, the junction temperature is determined from the junction-to-case thermal
resistance.
In many cases, it is appropriate to simulate the system environment using a computational fluid dynamics
thermal simulation tool. In such a tool, the simplest thermal model of a package which has demonstrated
reasonable accuracy (about 20%) is a two-resistor model consisting of a junction-to-board and a
junction-to-case thermal resistance. The junction-to-case covers the situation where a heat sink will be used
or where a substantial amount of heat is dissipated from the top of the package. The junction-to-board
thermal resistance describes the thermal performance when most of the heat is conducted to the
printed-circuit board.
