Identifying excessive temperature rise in components and in the board substrate. ![]() PCB thermal management focuses on three principle areas: Identify High Temperatures and Prevent Hot Components Before exporting into a PCB thermal analysis tool, there are some simple steps a designer can take to help manage heat generation in the board and prevent excessive temperature rise during operation. ![]() Once airflow is driven through the PCBA, the effect of airflow before prototyping can only be evaluated with CFD simulations, something with which not all designers may be familiar.ĭesigners that have access to these advanced field solvers should use PCB design software that can interface with PCB thermal analysis software within the standard workflow. Unfortunately, these are complex multiphysics problems that involve field solvers to fully evaluate. This requires pinpointing where heat will be generated and the expected temperature of components during operation, as well as understanding how the structure of a PCB substrate will aid heat transport. PCB thermal analysis can involve multiple tasks that are intended to evaluate heat transfer through the structure of the PCB. PCB design software for advanced electronics that interfaces with many 3rd party applications, including PCB thermal analysis software.
