Large-area extrusion coating

The FAS-Coat moving head extrusion coating system, for PDP, HDI, and AMLCD applications, coats substrate sizes up to 1200 ? 1600 mm. Because the extrusion head moves over the substrate, rather than the substrate`s moving under the head, less cleanroom space is required. The system offers uniformity of better than ?2% for photoresists, polyimides, and color filters. For PDP manufacturers, uniformity of ?3% can be obtained with glass frit, commonly used for producing barrier ribs. FAS-Coat comes with real-time automatic head leveling and head-height adjustment.
