Homebrew PCBs

Although I have not yet attempted it, my expectation is that it will work the same way bonding a 2 layer board out two singled PCBs works. Tape them together at first, but once several via are soldered into place the board will be stuck together well enough for many purposes.

With a 4 layer assembly the trick to access the inner layers is apparently to drill the outer via holes larger than the inner holes so that it is possible to solder the via connecting wire to both the inner and outer via copper plates. 

That extra drill for the outer layers may be more of a pain than its worth with through hole components. However, using SMD I'm hopeful the process will wind up reducing my overall drill count and increase my component density. 

Regards,
Royce
