24-Position Spin Coating System with Smart Material Recovery | Custom Chuck & Nozzle for Minimal Loss This material-saving 24-station spin coater is engineered to minimize photoresist, polyimide, or precursor solution waste in high-throughput coating lines. Unlike conventional spin coaters that discard excess liquid, our system integrates customizable edge bead removal (EBR) recycling, low dead-volume dispense lines, and pre-wet optimization logic to reduce material
