Address,

     How many suppliers are copper plugging .008 finish vias, provided the
     surface finish is OSP.  Provide your answer(s) on finished board
     thicknesses of .062 and .028, std tolerances.  If so, what percentage,
     nominal, are you able to plug shut.  Through cross-sectioning do you
     have the following conditions.

     From my past experience the plugging of vias is not feasible using an
     electroless and electrolytic plating combination process.
     Cross-sectioning would later show a dog-bone effect.  Does this still
     hold true today.

     Thanks,

     John Gulley
