In cases where board temperature is known, use the thermal
characterization parameter, ΨJB, to estimate the junction tem-
perature rise (see Figure 36). Maximum junction temperature
(TJ) is calculated from the board temperature (TB) and power
dissipation (PD) using the following formula:
TJ = TB + (PD × ΨJB)
(5)
The typical value of ΨJB is 58°C/W for the 4-Ball WLCSP package.
