I have just remembered other thing, once i read from some already dated
IPC documents, a way to activate the holes, beautiful for it simplicity.
Not much info just named and short explained, and that was still in
development.
It consists in activate while drilling. The drill bit, make de hole and
then entered in a metallic bath, when exit the hole will place the
metallic components in the hole wall, while still rotating.
Because all the dust made while drilling it should be better to drill
and clean first and then redrill with a tin or silver or other type
solution, in a soft cloth or so under the board.
It can be an old, forgotten and bad results experiment, i just remember
to name it here.
