VRM Burn‑In Test for Chip Power Adapters

As the computing power demand for AI agents surges, VRM power modules face the dual challenge of high‑current load testing (ranging from 10A to 1000A) and high‑temperature burn‑in. Heat dissipation control becomes increasingly difficult under high‑load operation, and conventional testing methods are inadequate for accurately simulating real‑world operating conditions and effectively managing thermal stress.

Project Overview

Project Background


Multiple projects have been implemented at benchmark foreign‑invested enterprises in China. With the surge in computing power demand for AI agents, VRM power modules are confronted with the dual challenge of high‑current load testing (ranging from 10A to 1000A) and high‑temperature burn‑in. Heat dissipation control becomes increasingly difficult under high‑load operation, and conventional testing methods are inadequate for accurately simulating real‑world operating conditions and effectively managing thermal stress.


The current manufacturing processes are primarily confronted with the following challenges

✅ Uneven heat dissipation during high‑current burn‑in, with insufficient temperature control precision, compromising test reliability.

✅ Low efficiency in manual loading, unloading, and sorting, failing to meet high‑frequency testing demands

✅ Dispersed socket connections and multi‑parameter monitoring (voltage, current, ON/OFF surge, temperature), making data traceability difficult.

✅ Insufficient analysis of mechanical stress and thermal fatigue on equipment under high‑temperature conditions, making it difficult to identify potential failure risks in a timely manner.


To overcome the heat dissipation challenges associated with high‑current testing, the project entails the construction of an automated VRM burn‑in testing line. The system employs a conveyor track and test tray configuration to automate the entire process of loading, burn‑in, unloading, and defective sorting. Equipped with Guanja's self‑developed socket, it provides integrated power supply, loading, temperature control, and stress analysis, ensuring accurate load testing at temperatures below 80°C, thereby significantly enhancing testing efficiency and reliability.
