Embodiment Construction

[0018] The following description is intended to enable those skilled in the art to reproduce and utilize the invention and to implement it using the best mode described by the inventors. There are various modifications to the invention which will be apparent to those skilled in the art. Any of these modifications, equivalent replacements and substitutions are within the inventive idea and scope of the present invention.

[0019] Since the workbench is an important part of the automatic substrate transfer system, the automatic substrate transfer system will be described first. figure 1 An automatic substrate transfer system including the workbench of the present invention is presented. The automatic substrate transfer system 2 is mainly described as a specific system for processing PCB substrates. The teachings of the present invention can be applied to any substrate with photopolymerizable substances that needs to be treated with a UV exposure system. The System 2 can handl...

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,...
