Thermal Analysis

C
Ambient temperature, air flow, board electrical operation and software operation affect board
component temperatures. To evaluate the thermal performance of a circuit board assembly, you
should test the board under actual operating conditions. These operating conditions vary
depending on system design.
A thermal analysis was performed in a representative system to verify operation within specified
ranges. Refer to
performance of the board in your application.
This appendix gives systems integrators the information necessary to conduct thermal
evaluations of the board in their specific system configuration. It identifies thermally significant
components and lists the corresponding maximum allowable component operating
temperatures. It also provides example procedures for component-level temperature
measurements.
