After coating processes (TCO, absorber and molybdenum), the one-sided removal of faulty coatings on the substrate surface (sunny side up) is required by wet-chemical etching. At the same time the functional surface must be protected from etching fumes.

Inline system for the one-sided removal of faulty coatings on the glass surface

• Effective and precise one-sided removal of the coating on glass surfaces by adjustable and controlled process parameters
• Optimal process guidance and protection of the functional surface against active chemical fumes.
• Processing of the glass substrate with a high rate of process safety and system availability.
