Webprocessing on 600 x 600mm2 panel over 300mm diameter wafer The tables demonstrate the productivity advantage of exposing on rectangular substrates versus circular wafers. In panel processing, the number of exposures per panel increases due to the larger area of the panel and processed panels per hour are less then processed wafers per hour. WebThe litho-laminating process can be sub-divided into three main types - inline, offline, and sheet to sheet. Some litho-laminating equipment can also be used for stand-alone single-face corrugated production or sheeting. The capabilities of any litho-laminating line will depend on the exact configuration of units included.
