Abstract

For PCB board carrying electrical current, it is generally desirable to be aware of any damage to the PCB track. Damage to PCB track may eventually result if the track exposed to the higher temperature than temperature limit of the PCB material. This situation is potentially resulting in a short circuit which may cause the PCB to fail. In preventing this problem, the period of erosion in PCB track due to the arc and temperature will be estimated from an analysis of temperature distribution in one dimensional PCB. The relation between current and temperature rise of a PCB with different width (size) and current that been inject to the track flow will be identified. An experiment will be set up to capture and analyze data using Minitab software and Microsoft Office Excel. From the tools we can analyze the temperature distribution. As a result, we will know between 2 parameters, which one is the most influencing thermal resistance.
