Abstract

The present invention relates to an operating platform with adjustable shims and method of automatically installing shims. The operating platform comprises a top surface, and a plurality of adjustable shims located below the top surface and around an edge of the platen, wherein the adjustable shims can be raised and lowered to a desired height to compensate for different sizes or thicknesses of substrates. The method comprises providing a group of electrical shims below the top surface of the operating platform, and raising or lowering the electrical shims on the basis of the size and height of substrates. By using the operating platform and the method, defects of manual installation of shims can be overcome, and production efficiency of PCB can be improved greatly.

Description

technical field

[0001] The present invention relates to apparatus for photolithography of exposed substrates and methods of using the apparatus, and more particularly to methods for improved tables and automated shim mounting thereof. 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. In a common practice, the substrate, also known as the panel, is placed on a workbench and exposed in an ultraviolet exposure system for about a few seconds to a minute. Substances in exposed areas of the plate will cure,...
