    Abstract: An apparatus includes an electrical device having a surface. The electrical device includes a first surface conductor spaced apart from a second surface conductor on the surface to provide circuit contacts to the device. A first standoff connector is bonded to the first surface conductor. The first standoff connector includes a leg having a proximal end bonded to the first surface conductor. The leg of the first standoff connector extends outwardly from the first surface conductor to a bend that is spaced apart from the surface of the electrical device. A second standoff connector is bonded to the second surface conductor. The second standoff connector includes a leg having a proximal end bonded to the second surface conductor. The leg of the second standoff connector extends outwardly from the second surface conductor to a bend that is spaced apart from the surface of the electrical device.

    Abstract: A fingerprint sensor is provided. The fingerprint sensor includes a sensing array sensing fingerprint information of a user, an insulating surface disposed on the sensing array, and a printed circuit board (PCB) disposed under the sensing array. The PCB includes a substrate, a ground plane disposed on the second surface of the substrate, and an electrostatic discharge (ESD) ring disposed on the first surface of the substrate and surrounding the sensing array. The substrate includes a first surface and a second surface opposite the first surface. The ESD ring surrounds the sensing array. When an ESD event occurs, ESD energy is discharged from the ESD ring to the ground plane through a plurality of vias in the substrate without passing the sensing array.
