//   Now include the  Thermal Land  copper on the Top side
//
//   and Bottom side copper for Ground connections.
//
//   Note that the bottom side metal  (aka backside metal) is
//   described on layer  Sheet_Dielectric_1.   See the as-built
//   file  Hub Trace Routing Details  for a description of how
//   the backside metal is handled in the Hub design.
//
//   Note that the backside metal is not symmetric wrt the
//   thermal/Gnd vias in the center pad.  I have built up
//   0.30 mm more metal on one side to make a tighter
//   connection to some of the bypass capacitors.
