Exchange method and mechanism for a component of the magnetic head and the suspension or the head gimbal assembly of the hard disk driver during manufacture

Abstract

A method and mechanism for visually inspecting both sides of components for a hard disk drive are disclosed. The components are stored in the containment units of a packing tray, with an exchange tray with matching containment units placed above and in contact with the packing tray. The components could be magnetic read/write heads, head gimbal assemblies, or other parts of hard disk drive. The two trays are rotated, using gravity to cause the components to move from the packing containment unit to the exchange containment unit.

1 . An exchange tray comprising: 
 an exchange containment unit matching a packing containment unit of a packing tray to receive a component of a hard disk drive; and    an exchange base to support the exchange containment unit.    
   
   
       2 . The exchange tray of  claim 1 , wherein the exchange tray is able to contain a plurality of components.  
   
   
       3 . The exchange tray of  claim 1 , wherein the exchange containment unit is an indentation shaped to hold the component.  
   
   
       4 . The exchange tray of  claim 1 , wherein the exchange containment unit is a set of pins to hold the component.  
   
   
       5 . The exchange tray of  claim 1 , further comprising a limiter attached to the exchange base to match a limiter of the packing tray.  
   
   
       6 . The exchange tray of  claim 1 , wherein the component is a magnetic read/write head.  
   
   
       7 . The exchange tray of  claim 1 , wherein the component is a micro-actuator.  
   
   
       8 . The exchange tray of  claim 1 , wherein the component is a head gimbal assembly.  
   
   
       9 . The exchange tray of  claim 1 , wherein the component is a head suspension.  
   
   
       10 . The exchange tray of  claim 1 , further comprising at least one pin hole in the exchange base matching at least one pin hole in the packing tray.  
   
   
       11 . The exchange tray of  claim 1 , wherein the component is moved from the packing tray to the exchange tray by positioning the exchange tray above and in contact with the packing tray and rotating the packing tray and the exchange tray together.
