Abstract
Abstract In an improved load board insertion system, a load board adapter ring is to seat a load board to a test head by turning a handle on the load board adapter ring; the load board has guide pins to align a pogo pin stand which is attached to the test head and the load board; the position ring has slanted roller slots which create downward pressure when the rollers on the load board adapter are forced up the slanted roller slots through load board adapter rotation.
