No warning lights. Just scrap—and an urgent call from lithography.</p> <h2 id="what-actually-matters">What actually matters</h2> <p>We built zoned heating around independent, closed-loop control of discrete thermal zones. Each zone runs on fast-response NIR emitters with a quartz-stabilized profile, holding repeatable setpoints from 150–300°C with ±0.1°C wafer-level uniformity. The heater block is built for Class 1–100 cleanroom use: low outgassing materials, no exposed adhesives, and a surface finish that keeps particle counts in check. Power runs through shielded, EMI-aware cabling, and the control firmware logs <a href="https://goldisgood.com">every</a> bake step with traceable recipe data—no guesswork, just documented repeatability.</p>
