Abstract
The use of a silicon electronic chip especially when driving and controlling a DC motor, causes an increase in the equipment’s temperature and influences its performance and data processing. Determining the temperature distribution throughout the system ensures the proper use and extends the chip’s life within its temperature limiting conditions. This study proposes a numerical solution of one heat transfer model of the chip using the finite difference method (FDM) applied for permanent regime for the original chip and simulating its substrate increasing in size, aiming optimization. Based on the results obtained, it is observed that the system has a temperature distribution within the manufacturer’s specifications and that increasing the dielectric substrate’s size contributes to the reduction of the heat transfer by convection.
