NOTES:
1.
THE INSIDE RADIUS OF ALL 16 HALF HOLES
AT THE PERIMETER OF THE BOARD ARE
PLATED TO PROVIDE A SURFACE FOR THE
ATTACHMENT OF THE VCO TO A PCB,
IN 13 LOCATIONS, WITH 3 PADS BEING
USED FOR ELECTROMECHANICAL INTERFACE.
16 SOLDER LOCATIONS REQUIRED.
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 IS GROUND AND ATTACHES
TO A GROUND TRACK ON THE UPPER SIDE OF
THE BOARD AS WELL AS THE SHIELD BY PTH.
4. UNLESS OTHERWISE NOTED ALL DIMENSIONS
ARE IN INCHES.
