On the fab floor, underfill curing isn’t a batch step—it’s a thermal budget you have to manage down to the degree. Miss by one, and CTE mismatch shows up, voids creep in, and the package ends up on the scrap pile. We built our IR curing platform for exactly that kind of reality. What matters, technically The system holds ±0.1°C steady-state uniformity across the substrate, with zone-by-zone mapping and control. Cleanroom Class 1–100 is baked into the design: low-outgassing materials, HEPA-integrated airflow, and an internal surface finish that keeps particle generation below 0.1/cm³. NIR energy is delivered with tight spectral control, so you get a fast, through-cure without pushing the glass transition too far. For photoresist bake—soft bake and hard bake—setpoint repeatability stays within 0.5°C, which keeps critical dimension control in spec. Why it holds up in production You can run this 24/7 and keep unplanned downtime low. Thermal ramps repeat cycle after cycle, so yield improves and rework drops off. Power draw comes down, too—low thermal mass plus short dwell means less idling and less wasted energy. The payoff is predictable adhesion, controlled warpage, and fewer recalibrations between lots. What you need to plan for The platform needs a dedicated clean power feed and stable cooling water at the specified pressure and temperature—thermal stability rides on both. Integration into an existing line is straightforward, but plan the footprint upfront. Airflow ducting and service clearance aren’t optional. Treat it like a process instrument, not a heater, and it will hold that ±0.1°C line, day after day.
