On an LCD panel fab floor, thermal drift doesn’t announce itself—it just quietly eats yield. Get the temperature even slightly off during photoresist soft bake or hard bake, and you’re setting up dimensional errors that follow the line straight through lithography, etch, and deposition. We designed our infrared heaters to kill that drift at the source. What matters under the hood We run short-wave infrared, so response is fast and thermal uniformity is tight. That’s what gives you repeatable bake profiles across large substrates. Control is closed-loop, and setpoints stay within tight tolerances so the thermal budget stays in spec. The heaters stay clean—no outgassing, no particle bursts when the temperature ramps—so they fit Class 1–100 environments without spiking particle counts. The construction is quartz-based, built for long life, with stable output that holds up over thousands of hours. Hookup is straightforward: standard electrical feeds and clean mechanical mounts that drop into existing process chambers. Why this plays well in an LCD fab In panel fabrication, you need heat where you want it, when you need it, without lag or hot spots. Our infrared heaters bring the substrate up to temperature quickly, then hold steady, so soft bake and hard bake stay consistent run after run. That stability keeps photoresist defects down, improves overlay accuracy, and reduces scrap. It also helps uptime: the unit starts, heats, and settles on schedule, so the line keeps moving. Energy use stays disciplined, too, because the heater targets the substrate directly instead of heating the whole chamber. The practical details you’ll want to plan for Installation needs a clear line-of-sight to the substrate and proper thermal isolation from nearby equipment, otherwise you risk cross-talk in the control loop. Commissioning is short—just enough time to tune the profile to your stack and cycle times. If you run near the upper end of the temperature range, thermal stress on the emitter picks up; set preventive replacement intervals based on your duty cycle so performance stays predictable.
