The inside radius of all 24 half holes at the perimeter of the board are plated to provide a surface for the attachment of the PLL Module to the PCB. 16 pads are for grounding, 8 pads are for signal interface. The surface of the shield is tin-plated and may be soldered to. The shield's base metal is cold-rolled steel. The ground plane on the bottom side is ground and attaches to a ground track on the top side of the board as well as to the shield. Unless otherwise noted all dimensions are in inches. Unless otherwise noted all tolerances are as follows: .xxx = .010.
