On the fab floor, burn-in doesn’t mean a thing if the heat source wobbles. A few degrees of drift across the chuck and you’re masking marginal devices—or tossing good die. We built these burn-in lamps to take that variability off the table. What matters under the hood We run short-wave halogen elements inside a quartz envelope, tuned to snap to temperature and hold it. You get wafer-level uniformity within ±0.1°C across the active bake zone, and the repeatability that keeps soft bake and hard bake profiles consistent, run after run. The system sits comfortably in Class 1 to Class 100 cleanrooms, with zero particle generation once it’s in steady state. Output stays stable on 24/7 duty, with measured drift below 3% after 5,000 hours, so your thermal budget stays predictable. Why it plays in burn-in Burn-in needs heat that hits fast, stays steady, and doesn’t leave crud behind. These lamps get to setpoint quickly, trim thermal settling time, and keep overshoot out of the photoresist window. The payoff shows up as fewer rework lots, less scrap, and a higher first-pass yield. We also keep energy use in check with efficient radiant coupling and tight thermal confinement, so you cut operating cost without slowing throughput. A few field notes These lamps are designed to drop into standard burn-in fixtures and probe stations, but alignment to the wafer plane is non-negotiable. Mounting tolerances and reflector geometry are tight—small mechanical variance will eat into uniformity. Plan a short commissioning run to lock down the thermal profile for your specific carrier and wafer stack.
