Plasma System
Vacuum Coating System
The surface improvement work using vacuum plasma is a technique widely used for improving the yield of a semiconductor chip package process, increasing adhesion, and the like. This plasma system is also used to remove residues remaining in a PCB laser hole by injecting Etching Gases or the like in a vacuum plasma state. Ziwoo technology uses such plasma technology to develop the Vacuum Plasma System, manufactures and supplies products, and recently Ziwoo Technology is actively embarking on to develop and commercialize an in-line cleaner using atmospheric pressure plasma.
