摘要：
A device for preventing damage to a pivot bearing assembly during manufacture of a hard disk drive includes a first bottom voice coil motor (VCM) plate hold-down clamp configured to clamp down on a first exposed surface of a bottom VCM plate of the hard disk drive and a second bottom VCM plate hold-down clamp configured to clamp down on a second exposed surface of the bottom VCM plate. The first and second bottom VCM plate hold-down clamps are configured to prevent damage to the pivot bearing assembly during installation of the top VCM plate over the bottom VCM plate by clamping down on the bottom VCM plate with a force that is at least sufficient to prevent the bottom VCM plate from moving when the top VCM plate is installed over the bottom VCM plate.
