Abstract:
1. A method of forming a colored appearance, suitable for forming a colored appearance for a conductive casing of a connector, wherein the conductive casing comprises a body and at least one lead, the lead extends from the body, and the conductive casing is suitable for being welded on a circuit board through the lead, the method of forming the colored appearance comprising: roughening a surface of the conductive casing; forming a conductive metal layer on the roughened surface of the conductive casing; forming a shielding layer on a part of the conductive metal layer located on the lead; forming a colored conductive layer on the conductive casing, wherein a part of the colored conductive layer is located on the conductive metal layer of the body, and the other part of the colored conductive layer is located on the shielding layer located on the lead; and removing the shielding layer and the part of the colored conductive layer located on the shielding layer to expose the other part of the conductive metal layer located on the lead.
