Title: Cliff C Zhang: Innovator in Measurement and Assembly Technologies
Introduction
Cliff C Zhang is a notable inventor based in San Jose, CA, with a focus on measurement circuitry and head stack assembly technologies. He holds a total of 6 patents, showcasing his contributions to the field of engineering and technology.
Latest Patents
One of his latest patents involves a method for measuring a load resistance coupled to a transmission line. This measurement circuitry is designed to be connected to a load through a transmission line. It applies a first AC signal at a specific frequency to the transmission line and measures the first input impedance. Subsequently, a second AC signal at a different frequency is applied, and the second input impedance is measured. A third AC signal, again at a different frequency, is applied, and the third input impedance is recorded. The resistance of the load is then calculated based on these measured impedances.
Another significant patent by Zhang details a method for head stack assembly rework. This method involves a first head gimbal assembly (HGA) that includes a suspension attached to an arm of the head stack assembly. The first HGA is removed by cutting the bonding region from the flexure tail and detaching the suspension from the arm. A replacement HGA is then installed by attaching a new suspension and bonding it to the existing structure.
