Introduction

Yang Rao is an accomplished inventor based in Rockledge, Florida, with a notable portfolio of six patents. His work primarily focuses on advancements in finger sensing technology, which has significant applications in various electronic devices.

Latest Patents

One of Yang Rao's latest patents is a method of making a finger sensor package. This innovative method involves advancing a flexible circuit tape along a predetermined path of travel. The flexible circuit tape consists of a flexible layer and conductive traces that define individual flexible circuits. As the tape is advanced, the method secures a respective finger sensing integrated circuit (IC) and surrounding sensor package frame to each flexible circuit. It also applies at least one fluid fill material adjacent to each finger sensor IC, using the corresponding sensor package frame as a dam to define the finger sensor packages. Finally, the finger sensor packages are stamped out from the flexible circuit tape to form at least one flush common edge of each sensor package frame and individual flexible circuit.

Another significant patent by Yang Rao is related to a finger sensing device that includes a finger sensing integrated circuit die within a recess in a mounting substrate. This device features conductive through-vias extending from the top surface to the bottom surface of the substrate, with the through-vias extending laterally adjacent to the recess. The finger sensing device also includes a dielectric layer over the mounting substrate and the finger sensing IC die, along with a conductive pattern that couples the conductive through-vias to respective bond pads.
