Project Background

This project has been implemented at a major domestic contract manufacturer for automotive products. As new energy vehicle technologies continue to advance, the reliability and thermal stability requirements for electronic control systems are becoming increasingly stringent. The functional stability of PCBA control boards and driver boards under high‑temperature conditions has become a critical factor in ensuring the long‑term reliable operation of e‑control systems. Traditional manual testing methods suffer from low efficiency, cumbersome changeover procedures, and inconsistent test results, making them inadequate for the high‑intensity, high‑precision demands of mass production.

The current manufacturing processes are primarily confronted with the following challenges:

✅ Low manual testing efficiency and frequent model changeovers, making it difficult to respond rapidly to production demands.

✅ Lack of standardised manual operating procedures, compromising test data consistency.

✅ High energy consumption and labour costs associated with high‑temperature testing.

✅ Untimely data collection and an incomplete quality traceability system.

To address the above issues, the client plans to introduce an automated high‑temperature burn‑in test line. The system features automatic rail width adjustment for rapid changeover across multiple models, and performs full‑process functional testing at 110°C. This solution will significantly improve testing efficiency and data accuracy, ensure stable product performance under high‑temperature conditions, and help the client build a highly reliable, intelligent testing platform.
