The etching modules have oscillating nozzles, which are arranged either parallel or at right angles to the conveying direction. This SCHMID achieves a uniform etch rate across the entire panel surface. A permanent monitoring of the process parameters guarantees ideal etch results.

• Automatic adjustment of pH
• High etching quality at high etching factor by using the Fineline spray System
• Uniform etching pattern through intermittend etching with single nozzle control
