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 VCO Module to the PCB. 21 pads are for grounding. 2. The surface of the shield is tin-plated and may be soldered to. The shield's base metal is cold rolled steel. 3.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. 4. Unless otherwise noted all dimensions are in inches. 5. Unless otherwise noted all tolerances are as follows: .xxx = .010 0.481 .055 BOTTOM SEE DETAIL A .032 P1 P2-12 P13 P14-16 P17 P18-24 RF OUTPUT GROUND VCC GROUND Vtune GROUND .015 .030 DETAIL B (TYP) (3 PLACES) SEE DETAIL B (c) Z-Communications, Inc.
