![]() ![]() Some components will obviously run at very high temperatures, such as large processors with high I/O counts. One step you can take to aid thermal analysis and ensure you’ve identified any hot components in the board is to use thermal resistance values for components to determine their operating temperature. However, if you can implement some basic analysis strategies before exporting your design into a PCB thermal analysis software program, you can reduce the extent of any required redesigns with some best practices for thermal integrity. The best time to use PCB thermal analysis software is once the PCB layout is completed but before prototyping. PCB thermal analysis software can help with these tasks at various points in the design phase. Moving heat from hot to cool areas via airflow or conduction.Selecting board materials to provide heat transport and produce an even temperature distribution.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. ![]()
