CAPACITIVE TOUCH SENSITIVE HOUSING AND METHOD FOR MAKING THE SAME
First Claim
1. A method for making a capacitive touch sensitive housing, comprising:
- forming a non-patterned active metal layer on a housing wall;
patterning the non-patterned active metal layer on the housing wall such that the non-patterned active metal layer is formed into a patterned active metal layer which includes a plurality of plating portions physically separated from each other, and a plurality of non-plating portions physically separated from the plating portions; and
forming a metal layer on the patterned active metal layer such that the metal layer has s first portions formed on the plating portions of the patterned active metal layer, and second portions formed on the non-plating portions of the patterned active metal layer.

Abstract
A method for making a capacitive touch sensitive housing, comprises: forming a non-patterned active metal layer on a housing wall; patterning the non-patterned active metal layer on the housing wall by laser ablation such that the non-patterned active metal layer is formed into a patterned active metal layer including a plurality of plating portions separated from each other, and a plurality of non-plating portions separated from the plating portions; and forming a metal layer on the patterned active metal layer such that the metal layer has first portions formed on the plating portions of the patterned active metal layer, and second portions formed on the non-plating portions of the patterned active metal layer.

8. A capacitive touch sensitive housing, comprising:
-
a housing wall having an insulative surface; at least one array of capacitive touch sensor pads formed on said insulative surface of said housing wall for providing touch input functions to an electronic device; a plurality of conductive bonding pads formed on said insulative surface of said housing wall and adapted to be electrically coupled to a circuit board of the electronic device; and a plurality of conductive lines formed on said insulative surface of said housing wall, each of said conductive lines extending from a respective one of said touch sensor pads to a respective one of said bonding pads and cooperating with the respective one of said capacitive touch sensor pads and the respective one of said bonding pads to define a touch sensor unit; wherein said touch sensor unit has a layered structure including an active metal layer and a metal layer that is formed on said active metal layer, said active metal layer being made from an active material containing an active metal that is capable of catalytically initiating the forming of said metal layer. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
