Vision alignment system outside of test site

A method of performing vision alignment of an integrated circuit device, the method comprising:

• providing a bottom contactor assembly comprising a bottom contactor contact array;
• providing a top contactor assembly comprising a top contactor contact army;
• providing a contactor vision alignment system located separate from a test site of an integrated circuit device testing system, the contactor vision alignment system comprising:
• a downward-looking camera configured to view the bottom contactor assembly,
• an upward-looking camera configured to view the top contactor assembly,
• an adjustment mechanism configured to move the top contactor assembly, and
• a controller;
• using the controller, and based on data received from the downward-looking camera and the upward-looking camera:
• determining an offset between the bottom side device contact array and the bottom contactor contact array,
• causing the adjustment mechanism to align the bottom side device contact array with the bottom contactor contact array based on the determined offset between the bottom side device contact army and the bottom contactor contact array,
• determining an offset between the top contactor contact array and the top side device contact array, and
• causing the adjustment mechanism to align the top contactor with respect to the top side device contact array based on the determined offset between the top side device contact army and the top contactor contact array.

A clamping mechanism configured to hold an integrated circuit device having a bottom side device contact array and a top side device contact array, the clamping mechanism comprising:

• a bottom contactor assembly comprising:
• a bottom contactor assembly frame, and
• a bottom contactor attached to the bottom contactor assembly frame, the bottom contactor comprising a bottom contactor contact array;
• a top contactor assembly comprising:
• a clamping apparatus, and
• a top contactor fixed to the clamping apparatus, the top contactor comprising a top contactor contact array;
• and
• a locking mechanism configured to removably attach the top and bottom contactor assemblies to each other while the integrated circuit device is located between the top contactor and the bottom contactor, and while the bottom side device contact array is connected to the bottom contactor contact array and the top side device contact array is connected to the top contactor contact array.
