PCB Trace Width Calculator

This calculator is used to determine the temperature of a PCB trace located on the first layer of a PCB. The calculation method uses a closed-form analytical solution for a multilayer structure based on Fourier series techniques to determine the conduction in the PCB. Convection and radation from the surfaces of the PCB are determine using emperical and analytical correlations.

Need to design a heatsink?

The HeatSinkCalculator offers online heat sink analysis software that allows you to analyze plate fins heat sinks cooled via radiation, and natural or forced convection. Multiple heat sources attached to the heat sink can be evaluated. In addition the calculator automatically determines the optimal dimensions of your heat sink to achieve the lowest heat source temperature. Click below to learn more.
