Classification: CPC H  G | IPC H

Claim 6:
7. A method for manufacturing a casing of an electronic device, comprising:
forming an insulating adhesive layer on a surface of a substrate;
forming an electroconductive layer on the insulating adhesive layer, wherein forming the electroconductive layer comprises:
forming an electroless copper plating layer on the insulating adhesive layer; and
forming an electrolytic copper plating layer on the electroless copper plating layer; and

applying a lithographic patterning process on the electroconductive layer to form a circuit having a pattern, wherein applying the lithographic patterning process on the electroconductive layer comprises:
forming a photoresist layer on a surface of the electroconductive layer;
aligning and exposing the photoresist layer to at least one of an infrared radiation and an ultraviolet radiation;
developing the photoresist layer to form a patterned photoresist layer;
etching the electroconductive layer, while using the patterned photoresist layer as a mask, to form the circuit with the pattern; and
removing the patterned photoresist layer from the surface of the electroconductive layer.
