Abstract
A system and method for improving piezoelectric micro-actuator operation by preventing undesired micro-actuator motion hindrance and by preventing micro-actuator misalignment during manufacture. A shim element is interposed between an electric circuit assembly and a lower portion of an actuator frame. The electric circuit assembly has a generally `O`-shaped portion configured so that an upper portion of said actuator frame is able to protrude through the `O`-shaped portion. The shim element is coupled between the electric circuit assembly and the lower portion of the actuator frame.
