Latest Patents

Leung's latest patents include a "Process for Testing a Head Stack Assembly" and a "Universal Fixture for HSA Assembly and Its Testing Process." The first patent describes a new fixture capable of holding a head stack assembly throughout all processes, allowing for a Quasi-Static Test to be conducted before swaging. This method includes loading head gimbal assemblies and actuators using an automatic loading machine, in-line dressing, ultrasonic bonding, and testing of the assemblies. If any assembly fails the testing, it can be rejected and reworked in-line, followed by coating, ultra-violet curing, swaging, and visual checking.

The second patent introduces a universal fixture designed to hold a head stack assembly throughout all processes, which simplifies handling operations and makes rework easier. This invention also provides a process for testing the head stack assembly using the fixture.
