Contact sensor package structure

摘要

A contact sensor package has a substrate, a film, a sealant and a plurality of contact sensors disposed on the substrate. The contact sensors are disposed within the enclosed space defined by the substrate, the film and the sealant. The contact sensor package further has at least a ground conductive trace formed on the substrate and an electrostatic charge dissipation layer formed on a surface of the film and electrically connected to the ground conductive trace. The electrostatic charge dissipation layer has an upper surface that serves as a contact surface for a detecting a contact work-piece.
