NON-CONDUCTIVE METAL GLOSS PLATING, CASE FOR ELECTRONIC DEVICE WITH NON-CONDUCTIVE METAL GLOSS PLATING, AND METHOD OF FORMING NON-CONDUCTIVE METAL GLASS PLATING

摘要

PROBLEM TO BE SOLVED: To provide a non-conductive metal gloss plating and a method of forming the non-conductive metal gloss plating which are effective as a remedy against the electrostatic breakdown of a resin-made plate or a resin-made case.;SOLUTION: The non-conductive metal glass plating has a constitution comprising a first resin coating layer formed on the surface of a substrate to be coated by application and drying, a non-conductive metal vapor deposition film having a metallic luster and being extremely thin obtained by heating an alloy including a tin or a tin and an indium in vacuum and performing a vacuum deposition onto the first resin film coating layer on the above substrate, and a second resin film layer formed by the application and drying on the above non-conductive metal vapor deposition film. Since the above deposition is stopped before the grains of the above tin or alloy of tin and indium form a continuous metal film on the above first resin coating film layer, the above metal vapor deposition film becomes non-conductive and the static electricity does not pass through the surface though it has metallic luster, and does not have an electromagnetic shielding action.;COPYRIGHT: (C)2007,JPO&INPIT
