Abstract:
A method of making finger sensor packages may include advancing a flexible circuit tape along a predetermined path of travel. The flexible circuit tape may include a flexible layer and conductive traces thereon defining individual flexible circuits. The method may include, as the flexible circuit tape is advanced along the path of travel, securing a respective finger sensing integrated circuit (IC) and surrounding sensor package frame to each flexible circuit, applying at least one fluid fill material adjacent each finger sensor IC while using the corresponding sensor package frame as a dam to thereby define finger sensor packages, and stamping out the finger sensor packages from the flexible circuit tape to form at least one flush common edge of each sensor package frame and individual flexible circuit.
