Thermal Calculation and Measurement
Figure 3. Effect of Board Temperature Rise on Thermal Behavior
If the board temperature is known, an estimate of the junction temperature in the environment can be made using
the following equation:
TJ = TB +(RθJB x PD)
where:
RθJB = junction-to-board thermal resistance (C/W)
TB = board temperature C
PD = power dissipation in package
If the board temperature is known and the heat loss from the package case to the air can be ignored, acceptable
predictions of junction temperature can be made. For this method to work, the board and board mounting must be
similar to the test board used to determine the junction-to-board thermal resistance, namely a 2s2p (board with a
power and a ground plane) and vias attaching the thermal balls to the ground plane.
7.4
Estimation Using Simulation
When the board temperature is not known, a thermal simulation of the application is needed. The simple two-resistor
model can be used with the thermal simulation of the application [2], or a more accurate and complex model of the
package can be used in the thermal simulation.
