Flux evaporation for wafer bump

On the 300mm line, flux residue after wafer bump formation isn’t just contamination. It’s a reliability bomb waiting to go off. Incomplete evaporation leaves voids and bridging, and suddenly your scrap rate climbs while your thermal budget gets pushed past the edge. We built this system to kill that waste where it starts. What actually matters under the hood The unit hits rapid, controlled flux evaporation with short-wave infrared, and keeps a ±0.1°C uniformity across the wafer. Quartz emitters deliver clean, particle-free heat, and the exhaust path is compatible with a Class 1–100 cleanroom, so you’re not inviting contamination into the chamber. Repeatability is baked into every bake cycle—soft bake through hard bake—with recipe control that locks temperature and time to spec. Carbon fiber insulation cuts energy drift and keeps setpoints stable, even when you’re running high-throughput lots. Why this works in the real flow Whether you’re in wafer drying, lithography, or packaging curing, the requirement is the same: thermal control that doesn’t cost you yield. This platform drops straight into bump lines, removing flux precisely without damaging under-bump metallization. Photoresist processing stays within tolerance, cleaning and drying cycles finish faster, and the line sees fewer reworks. Energy use drops because the system heats on demand and holds steady without overshoot, so you can run 24/7 with maintenance intervals you can plan around. The practical details you’ll want to line up Footprint is compact, but you’ll need exact utility alignment: dedicated exhaust, clean dry air, and stable voltage. Commissioning is short, but you’ll spend it tuning the exhaust balance to your specific flux formulation and wafer stack. Once that’s dialed in, the process window tightens the risk of voiding and residue. Match the flux to the profile, and the results take care of themselves.
