Semi-flexible substrate handling and processing
Flat Panel Display (FPD) manufacturing
The Flat Panel Display (FPD) manufacturing industry has stringent requirements for the handling, processing and inspection of glass; where glass can be considered a semi-flexible substrate. Precision, non-contact handling of the glass is required for both optical inspection and for LCD printing. Vacuum pre-loaded air bearings control the vertical height of the glass within < 5 µm for inspection. Vacuum grooves, distributed within the bearing, are used to improve vertical stiffness during printing. This also allows high speed transport at fixed height while avoiding take-off. Similar techniques are also used in Photovoltaic Solar Panel processing.
