Burn-in / Ageing Chamber

Selection criteria

Temperature uniformity, number of channels, load and power-cycling control, monitoring and logging.

Supply chain

Shenzhen and Dongguan have many makers of burn-in rooms and racks for power electronics, usually built to order. Set burn-in conditions from failure data rather than habit — over-long burn-in costs capacity without adding quality.

Buyer FAQ

How long and how hot should burn-in be?

Typical power-electronics burn-in runs a few hours to about 24 hours at roughly 40–60 °C, often with on/off power cycling. Start conservatively for a new product, record when failures occur, and shorten the duration once the early-failure rate stabilises. Failures appearing late in the cycle suggest a design or process problem that burn-in will not fix.

What temperature uniformity and load setup should I require?

Specify about ±2–3 °C for cabinets and ±3–5 °C for walk-in rooms, verified with the units under load, because the products themselves add heat. Choose loads that match real operation: resistive or electronic loads for boards, and loaded or no-load running for motors. Energy-recovery electronic loads that feed power back to the grid cut running cost significantly for high-power products.

What monitoring and safety features matter?

Each channel should log voltage, current and temperature against the unit serial number and flag failures with a timestamp. Require independent over-temperature cut-off, smoke or fire detection, grounded racks and per-channel fusing. Data that cannot be traced to serial numbers makes burn-in useless as quality evidence for customers.
