ABSTRACT:
A novel method and device to align a flexure tail of a head gimbal assembly (HGA) to a flex cable of a head stack assembly (HSA) is disclosed. An alignment pin is passed through a first alignment hole in the flex cable, and a second alignment hole in the flexure tail. The second alignment hole is disposed in a region of the flexure tail that lies in a flexure tail plane that is approximately parallel to the flex cable plane adjacent the first alignment hole. A novel head gimbal assembly (HGA) has a flexure tail that includes a first bend line. The flexure tail is bent out-of-plane about the first bend line to create a residual bend angle in the range 10° to 80°. The first alignment tab is abutted against a first guide surface of an alignment fixture.
