To anyone who can help

I have a design that requires Castelated Via's (via's that have their
centres lie on the edge of a board, where after a machining operation only
half of the via is left exposed).

The via's are 0.025" @ 0.100" centres with a total of 17 via's.

I would like to know if anyone knows of a functional process that will not
damage or push in the barrel of the hole or leave slivers after the process
is completed.

Your help is appreciated.

Ted
