Component Temperature Measurement
The following sections outline general temperature measurement methods. For the specific
types of measurements required for thermal evaluation of this board, see

Preparation
We recommend 40 AWG (American Wire Gauge) thermocouples for all thermal measurements.
Larger gauge thermocouples can wick heat away from the components and disturb air flowing
past the board.
Larger gauge thermocouples can wick heat away from the components and disturb air flowing
past the board.
Allow the board to reach thermal equilibrium before taking measurements. Most circuit boards
will reach thermal equilibrium within 30 minutes. After the warm up period, monitor a small
number of components over time to assure that equilibrium has been reached.
