20130084405 | METHOD FOR FORMING CIRCUITS ON HOUSING BY SPRAYING AND LASER ENGRAVING - A method for plating circuits on a housing by spraying and laser engraving is provided. Before manufacturing the circuit, a first spraying layer is formed. The thickness of the first spraying layer is approximately equal to that of the circuit to be formed thereon. Laser engraving is used to form laser engraving areas for forming the circuit metal layer. Then the circuit metal layer is formed by chemical plating, and the thickness of the metal layer is approximately equal to that of the first spraying layer. Then a second spraying layer is applied on both of the metal layer and the first spraying layer so as to present a flat and aesthetic appearance. As the present invention is applied in 2-shot molding, each time the pattern of the circuit is changed, it is only necessary to change the paths in the laser engraving. No more molds modification is needed for changing the pattern of the circuit. | 04-04-2013 |
