Patent ID: 8692790

Claim:
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 an electroless deposited metal layer that is electroless deposited 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 electroless deposition.
