Homebrew PCBs

I have soldered the wires directly to "strips" of copper.
(like a edge connector)
Holes would be tiny, or offset, and the wire is not solid and hard to 
insert.

The strip pads are possible with a small enough pitch (same as cable)

You should add some mech. restraint, maybe glue.

worked fine for me.
