1. A method of making a plurality of finger sensor packages comprising:

  • advancing a flexible circuit tape along a predetermined path of travel, the flexible circuit tape comprising a flexible layer and conductive traces thereon defining a plurality of individual flexible circuits; and

    performing the following steps as the flexible circuit tape is advanced along the path of travelsecuring a respective finger sensing integrated circuit (IC) and surrounding sensor package frame to each individual 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 a plurality of finger sensor packages, andstamping out the plurality of 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.
