To extend clearance and eliminate potential shorts to the bottom
of a connector, the component side pad must be reduced to zero.
In other words,a top side padless PTH. The shorts are occuring during
wave solder.

   What reliability down sides can we expect? Im advised that PCB
fabrication will not be a problem. Im mostly concerned with assembly
and repair operations.

  Parameters: .093", 14 layer board
               Finished hole .033" with solder side pad at .060"
               No external layer traces or connections.
               All connections are internal planes.
