ETCHING DEVICE AND METHOD FOR ELECTROLESS PLATING

摘要

An etching device and a etching method for electroless plating are provided to perform a light catalyst etching using ultra violet and visual light as well, and increase etching efficiency by having an excellent dispersion property. An etching device for an electroless plating includes a belt type fixing frame(6), a sol supply(10), a retrieve container(14), a pipeline(12), and a pump(13). The belt type fixing frame is turned around by a roll(8) and fixes components to be etched. The sol supply supplies titanium dioxide sol in an upper part of the belt type fixing frame. The retrieve container retrieves the titanium dioxide sol in a lower part of the belt type fixing frame. The pipeline connects the retrieve container and the sol supply for transporting the titanium dioxide sol from the retrieve container to the sol supply. The pump is connected midway through the pipeline.
