Abstract
An RF pallet ground comprises overhangs disposed at opposite ends. Each overhang includes a downwardly protruding ledge and a notch defined in a bottom surface of the pallet. The ledges and notches extend from one side of the pallet to the other. The ledge provides a positive connection directly to ground. The ledge has a length shorter than the length of the main body of the pallet. Fasteners are positioned on either side of an RF trace on the pallet, allowing positive pressure to be applied to the ground through the ledge.
