A capacitive touch sensitive housing comprises: a housing wall; an array of capacitive touch sensor pads formed on the housing wall; a plurality of conductive bonding pads formed on the housing wall; and a plurality of conductive lines formed on the housing wall. Each conductive line extends from a respective one of the touch sensor pads to a respective one of the bonding pads and cooperates with the respective one of the capacitive touch sensor pads and the respective one of the bonding pads to define a touch sensor unit having a layered structure including an active metal layer and an electroless deposited metal layer. The active metal layer contains an active metal capable of initiating electroless deposition.
