Homebrew PCBs

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.
