Embodiment Construction

[0019] 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.

[0020] Since the workbench is an important part of the high-speed vacuum workbench system, the high-speed vacuum workbench system will be described first. figure 1 A high speed vacuum table system including the table of the present invention is presented. The High Speed ​​Vacuum Bench System 2 is primarily 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 High Speed ​​Vacuum Table Syst...

Abstract

The present invention relates to a platen, a high speed vacuum platen system and a high speed vacuum forming method. The platen comprises a top surface having a plurality of openings, an enclosed plenum area below the top surface, and a large orifice valve connecting the plenum area to a high flow vacuum pump. The high speed vacuum platen system comprises a platen having a top surface having a plurality of openings, an enclosed plenum area below the top surface, and a switchable large orifice valve, having a port with an opening of at least 25 mm, connecting the plenum area to a high flow vacuum pump and to atmosphere, and a high flow vacuum pump connected to the switchable large orifice valve. The high speed vacuum forming method is applied to the platen and the high speed vacuum platen system. The invention improves the flowline production efficiency of PCB.

Description

technical field [0001] The present invention relates to a system and method for exposing photoresisting substances on a substrate, more specifically, to an improved workbench for carrying a substrate, a high-speed vacuum workbench system and a high-speed vacuum forming method. Background technique [0002] Traditionally, printed circuit boards, or PCBs, have required photopolymer coatings to define circuits during the manufacturing process, or protective coatings after the circuits have been printed to protect the circuits and prevent short circuits during component assembly. In both cases photopolymerizable organic coatings are 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...
