Regarding to the Cold Board, can we add another PCB design
to the current panel (if we have a space there)?   This is
smaller board for another experiments we are planning in
the lab.  The design is much easier for this one:

 1. Board size is 25x14 mm^2. Corners are rounded,
    radius is 0.8 mm  (fig1)


 2. Chip trench area is 7x2 mm^2. We can use the same
    parameters for this region (a larger trench area and a
    little bit exposed dielectric) as in Cold Board.

    We can make a bigger mouse ears here.

    Bottom side - the same 3 holes as in Cold Board.


 3. uwave trace parameters:

    a) at the edges of the board width = 0.5 mm, gap = 0.30 mm

    b) at the chip trench area   width = 0.3 mm, gap = 0.18 mm

    see (fig2)


 4. Vias should be placed along the uwave traces  (same size
    and spacing as in Cold Board)

 5. Four red circles are through holes  (fig3)

Regarding to the new board:

 1. This is the SMA connector [www.digikey.com] we want to use.

            SF2950-6200/SF2950-6200-ND/6201788

    We will solder the central pin to the PCB.

 2. Name: NV Board. “NV” stands for nitrogen vacancies in
    diamond, and this is the research project Joe Kitzman
    is gonna do in our lab.

 3. Quantity: 4.
