PRODUCTS HAVING METALLIC PATTERNS AND METHOD OF OBTAINING SAME |
摘要 |
The invention relates to a method of manufacturing a body having a gold pattern in which an etchant-resistant and electrically insulating masking layer is provided locally on the surface of a gold layer present on the body and parts of the surface of the gold layer not covered by the masking layer are subjected to a chemical etching treatment in an etching bath in which the gold pattern is formed. According to the invention, the gold layer during the chemical etching treatment is given a potential with respect to an electrode in the etching bath and this potential is adjusted to a value such that the etch rate is maintained at a rate no higher than the rate of the chemical etching treatment. |
