Abstract

A disk drive component flow fixture is described including a base fixture, and one or more child fixtures. Each of the one or more child fixtures is configured, for example, for removable insertion into the base fixture, and to receive a disk drive component. In an embodiment, a method for analysis of disk drive components is described using the disk drive component flow fixture, the method including inserting a first child fixture into a base fixture, placing a first disk drive component for a first type of disk drive onto the first child fixture, and performing an analysis of the first disk drive component.

Claims (38)

1. A hard disk drive component flow fixture comprising:

a base fixture having a child fixture reception unit; and

one or more child fixtures, wherein each of the one or more child fixtures is configured for removable insertion into the child fixture reception unit of the base fixture, and to receive a disk drive component, and

wherein each of the one or more child fixtures comprises a disk drive component reception unit configured to receive the disk drive component, and to rotate from a first position to a second position.

2. The flow fixture of claim 1 wherein the first position and the second position are separated by 90 degrees.

3. The flow fixture of claim 1 wherein the first position permits a visual mechanical inspection of the disk drive component, and the second position permits a slider ID inspection of the disk drive component.

4. The flow fixture of claim 1 wherein the base fixture comprises a rotatable clamp configured to apply pressure on the disk drive component to maintain the disk drive component on the disk drive component reception unit.

5. The flow fixture of claim 1 wherein the disk drive component comprises a head gimbal assembly.

6. The flow fixture of claim 1 wherein the disk drive component comprises an actuator, a pivot, a voice coil, or a flip chip on flex (“FCOF”).

7. The flow fixture of claim 1 wherein the disk drive component comprises a head stack assembly.

8. The flow fixture of claim 1 wherein the base fixture comprises a first locking mechanism and each of the one or more child fixtures comprises a second locking mechanism, wherein the first locking mechanism and the second locking mechanism are configured to cooperate with each other to allow the one or more child fixtures to be inserted into the base fixture, and prevent lateral movement of the one or more child fixtures.

9. A method for analysis of disk drive components using a hard disk drive component flow fixture comprising a base fixture and one or more child fixtures configured to be removably inserted into the base fixture and to receive a disk drive component comprising:

inserting a first child fixture into a child fixture reception unit of a base fixture;

placing a first disk drive component for a first type of disk drive onto the first child fixture; and

performing an analysis of the first disk drive component,

wherein the disk drive component flow fixture further comprises a second child fixture configured to be removably inserted into the base fixture, and to receive a second disk drive component for a second type of disk drive different from the first type of disk drive.

10. The method of claim 9 further comprising:

removing the first child fixture from the base fixture;

inserting the second child fixture into the base fixture;

placing the second disk drive component onto the second child fixture; and

performing an analysis of the second disk drive component.

11. The method of claim 9 wherein the first disk drive component comprises at least one of a head gimbal assembly or a head stack assembly.

12. The method of claim 9 wherein the first disk drive component comprises an actuator, a pivot, a voice coil, or a flip chip on flex (“FCOF”).

13. A hard disk drive component flow fixture comprising:

a base fixture having a child fixture reception unit; and

one or more child fixtures, wherein each of the one or more child fixtures is configured for removable insertion into the child fixture reception unit of the base fixture, and to receive a disk drive component, and

wherein the one or more child fixtures comprises a first child fixture configured to receive a first disk drive component for a first type of disk drive and a second child fixture configured to receive a second disk drive component for a second type of disk drive different than the first type of disk drive.

14. A method for analysis of disk drive components using a hard disk drive component flow fixture comprising a base fixture and one or more child fixtures configured to be removably inserted into the base fixture and to receive a disk drive component comprising:

inserting a first child fixture into a child fixture reception unit of a base fixture, wherein the first child fixture comprises a disk drive component reception unit configured to receive a first disk drive component for a first type of disk drive, and to rotate from a first position to a second position;

placing the first disk drive component onto the first child fixture; and

performing an analysis of the first disk drive component.

15. The method of claim 14 wherein the first position and the second position are separated by 90 degrees.

16. The method of claim 14 wherein the first position permits a visual mechanical inspection of the first disk drive component, and the second position permits a slider ID inspection of the first disk drive component.

17. The method of claim 14 wherein performing an analysis of the first disk drive component comprises:

performing a visual mechanical inspection of the first disk drive component;

rotating the disk drive component reception unit from the first position to the second position; and

performing an analysis of a slider ID on the first disk drive component.

18. The method of claim 14 further comprising applying pressure, using a rotatable clamp of the base fixture, on the first disk drive component to maintain the first disk drive component on the disk drive component reception unit.
