Claim 17:
18. A test head frame comprising:
a test head body;
a pair of telescopic rails attached to the test head body;
a tray coupled to the pair of telescopic rails, the tray slidable via the telescopic rails between an ejected position outside the test head body and a retracted position within the test head body, wherein the tray includes two longitudinal bars with spaced projections to enable removable attachment of a carrier plate configured to hold a first printed circuit board (PCB) to be tested;
a first pogo frame sized to accommodate a first plurality of pogo blocks containing a first plurality of pogo pins connected to a first plurality of pogo printed circuit boards positioned between the first pogo frame and the first plurality of pogo blocks, wherein the first pogo frame is arranged such that the first plurality of pogo blocks opposes a first plurality of interface printed circuit boards (PCBs) attached to a stiffener frame to which a bed of nails is attached when the stiffener frame is removably attached to the test head frame; and
a press down mechanism configured to move in a first direction to cause, when the tray is in the retracted position and the carrier plate with the first PCB is attached to the tray, the carrier plate and the first PCB to engage a plurality of spring-loaded pins in the bed of nails to form an electrical connection to the first plurality of interface PCBs.
