Abstract

The present invention provides an automatic substrate transport system and method to transport substrate through a lamp exposure system. The system comprises a first platen, the first platen having a plurality of holes on a top surface to allow forced air to produce an air film to support a substrate; a flipper module configured to receive a substrate from the first platen, and to rotate in orderto flip the substrate, the flipper module having a top interior surface and a bottom interior surface, wherein the top and bottom interior surfaces provide a plurality of holes for froming an air film to support the substrate; and a second platen configured to receive the substrate from the flipper module, the second platen having holes on a top surface to allow forced air to produce an air film to support the substrate. The method includes use steps corresponding to the system. In the system and method, the substrate is transported substantially on a film of air, to avoid substrate scratch and transfer of thickness substance caused by contact, to further improve the flowing production efficiency of PCB.

Description

technical field [0001] The present invention relates to systems and methods for exposing lithographic materials on substrates, and more particularly, to automated substrate transport systems and methods for transporting substrates through an exposure system. Background technique [0002] Traditionally, printed circuit boards (i.e. PCBs) have required photopolymer coatings to define circuits during the manufacturing process, or protective coatings to protect the circuits after the circuits have been printed and prevent short circuits during component assembly. In both cases described, a photopolymerizable organic coating is used. Ultraviolet rays are used during the manufacture of PCBs to activate the polymerization of coating substances, ie to cure photopolymerizable substances. A common practice is that the substrate, also known as the panel, is exposed in an ultraviolet exposure system for about a few seconds to a minute. Substances in exposed areas of the plate will cur...
