After board is cut,

We can solder the .003 copper wire across the opening. I soldered five wires across the opening, approximately equally spaced.. One one side I soldered a 22 guage insulated wire that would connect the assembly to ground.

Next I obtained a 1/8" thick x 1" x 3/5" metal plate. To this I attached copper foil tape to make an electrical connection. Just about any metal can be used for this plate. You can also use copper clad PC board. The main criteria for the plate is that it doesn't flex or bend.
