A method for forming a back-drilled plated through hole in a printed
circuit board and the resulting printed circuit board are described
herein. In the preferred embodiment, the printed circuit board includes a
via extending through a plurality of stacked layers. The via includes a
plated through hole and a back-drilled hole. The plated through hole is
located within a predetermined number of the stacked layers and the
back-drilled hole is located within the remaining stacked layer(s). The
plated through hole without an electrically conductive material located
on walls therein has a diameter that is substantially the same size or
smaller than the diameter of the back-drilled hole.
