Patent ID: 8373664

Claim:
A method, comprising: providing a first circuit board including a first capacitive sense array of sense elements and interconnecting sensor traces disposed on a first side of the first circuit board and a second capacitive sense array of sense elements and interconnecting sensor traces disposed on a second side of the first circuit board, wherein the first circuit board comprises no active electronic components to detect a presence of a conductive object on the capacitive sense array; and detecting a presence of a conductive object on the first and second capacitive sense array of the first circuit board using active electronic components of a second circuit board coupled to the first circuit board, wherein the second circuit board is one-sided and comprises a set of conductive contacts on one side of the second circuit board, the set of conductive contacts to provide signals from the first capacitive sense array of sense elements and the second capacitive sense array of sense elements to the active electronic components, and wherein the first and second circuit boards are coupled with a pressure contact connector having conductive ink traces coupled to the first interconnecting sensor traces and to the set of conductive contacts, and wherein the second interconnecting sensor traces are coupled directly to the set of conductive contacts on the one-sided second circuit board.
