ABSTRACT:
The present invention provides a method for assembling a head gimbal assembly useful in a hard disk drive and for testing such an assembly. In a method in accord with the present invention a head/slider is mounted to a circuited gimbal in an automated assembly machine. Following this step the head/slider circuited gimbal assembly will be subjected a dynamic electrical test with those head/slider circuited gimbal assemblies not passing being sorted from the lot. Following this step the head/slider circuited assembly will be attached to a suspension.
