Abstract
A method of manufacturing a tri-stage assembly is described herein. The method includes attaching a first microactuator and a second microactuator to a trace gimbal to a flexure during a PZT on flexure process (POF). The first microactuator is located at a distal end of the flexure and the second microactuator located at a proximal end of the flexure. The method also includes welding the trace gimbal to a baseplate, and a load beam to secure the trace gimbal including the first microactuator and the second microactuator.
