Summary:
This paper reports design method and characteristic analysis of a 2-layers metallic substrate module for a turbo charger BLDC motor driver. A module design methodology is suggested to protect system performance degradations of a 2-layers PCB system compared with a 4-layers system. A design flexibility of 2-layers PCB is limited because power-ground planes and signal traces have to share the same planes. Also, the thermal problem is more critical than 4 layers module. For the avoidance of these problems, the 2-layers metallic substrate module was designed with the design concept considered about thermal spreading pattern, PI, EMC and current return paths. The results of the 2-layers metallic module show the good performance on thermal spread characteristic and EMI characteristic to meet the given system compliance.
