Background:

Recently, we received a request from Electra Motors, an electric vehicle manufacturer, to develop a ceramic PCB for their advanced power electronics. Electra Motors aimed to improve the electrical performance and reliability of their electric vehicles.

PCB Challenge:

Electric vehicle power electronics require high power density and efficient thermal management. The existing PCBs in Electra Motors' vehicles were unable to withstand the demanding operating conditions, leading to performance degradation and reliability issues.

Solution:

Understanding the challenges faced by Electra Motors, our team proposed utilizing aluminum nitride as the base material for the ceramic PCBs. Aluminum nitride exhibits excellent thermal conductivity and superior electrical insulation properties, making it ideal for power electronics applications. We optimized the design by carefully selecting trace widths and implementing a multilayer structure to accommodate the high-power density requirements.

Result and Benefits:

After implementing the ceramic PCBs in Electra Motors' electric vehicles, significant improvements were observed. The aluminum nitride PCBs efficiently dissipated heat, ensuring optimal performance and preventing overheating-related failures. The enhanced electrical properties of the ceramic PCBs resulted in improved power conversion efficiency and overall vehicle reliability. Electra Motors commended our professionalism and acknowledged the innovative solution we provided. They expressed their intent to continue partnering with us for future ceramic PCB requirements in their electric vehicles.
