Abstract
A mechanical system for handling large and thin glass plates of dimensions as much as 2 m by 2 m by 0.5 mm, such as used to manufacture LCD panels in LCD panel testers, provides for positioning of the repair and inspection equipment by using lightweight hollow chucklets in air-bearing and vacuum contact with the glass plate under test, balanced on a rail along the center of mass for translation without warping. The elimination of a heavy rigid platform results in significantly reduced hardware costs, flexibility in processing and improved positioning performance.
