Printed circuit board etching machine using vaccum generator

Abstract

The objective of this paper is to design the etching machine for manufacturing printed circuit board. It is used to reduce the man power. It also reduces the time to complete the etching process, saving cost without using an expensive machine. Even though we already have an etching machine, usually it is placed in an industry that construct electronic circuits and that will makes us difficult to use all the time. It can be done manually by shaking the PCB board in a container that dissolve with etching liquid which is costly.
