Glass Lid with UV Protection in the Developer

Always up to date!

Available for all developers

The experienced design engineers from SCHMID systematically work on the optimization of our machines. Within this framework upgrades are regularly developed, which are completely compatible with your machines and can be built in by our service technicians – an investment that pays. Take advantage of this! Increase your yield on a long-lasting basis!

Previous Application

Upgrade: Glass lid with UV protection

Advantages

An uncontrolled exposure of the resist before and during the development can lead to image defects or e.g. oblique flanks. In both cases this leads to increased rejects since the printed circuit boards usually no longer meet the required criteria.

Uncontrolled exposure of the resist can be prevented by applying a UV protection on the glass lid in the developer. This results in a significantly higher yield.

Optionally, a plastic cover across the input module provides additional exposure protection.

  • Quality improvement
  • Avoidance of rejects
  • Prevention of uncontrolled exposure of the resist
  • Higher yield

Additional Information

SCHMID Global Services

The UV protection film with an extended absorption spectrum is particularly efficient in the range between 380 and 450 nm. This film is especially suitable for light-sensitive areas, e.g. for lithographic applications and photo labs. For wave lengths between 300 and 380 nm, the transmittance is even at <1%.

Your production line of yesterday may soon be a
production line of tomorrow. Since after the targeted intervention of our experts it will be state-of-the-art, and in fact at a significantly lower price than a new acquisition. With our upgrades you can maximize your output, increase the quality and expand your product
portfolio.
