A very important advancement in Electro-Chemical Marking has been the development of the Stencil Cleaner Tray. It is connected to the power unit with the yellow cord. The tray is made of polyethylene with a graphite block insert on which the cleaner tray wick is placed. Electrolyte is saturated in the wick and serves as a reservoir for production marking. When the stencil is blotted with the hand pad in the tray, reverse polarity flushes the oxides out and replenishes the hand pad wick with fresh electrolyte. This procedure is mandatory for extended stencil life. It produces far superior and consistent results in deep etch applications.
