Homebrew PCBs

You know, a company i worked for, they pressed in 0.64mm headers into THP  
boards, as backplane, press fit, no soldering, and it worked well.
I reckon if one got roundabout that size square wire it would be good,  
since thinner wire mightn't take any pressure.
Maybe using extra long wirewrap headers is an option.

Anyway, i rarely use vias, i needn't worry.
