Non‑contact vertical developing line adopts non‑contact conveying methods such as edge clamping. The substrates complete highly‑uniform developing while travelling vertically, completely eliminating scratches and roller marks. The vertical structure reduces clean‑room footprint, optimizes liquid flow and bubble control. Designed for mass production of fine line circuits such as IC substrates, flexible circuits and advanced‑packaging panels, the equipment significantly improves fine‑line yield.
