Homebrew PCBs

Hi All,

I am looking for some method to plug a pre-made device into a hole to 
work like a plated thru hole.

I remember some discussion of this last year and there was some 
supplier who evidently doesn't have a US supplier.

What do you do for the one's and two's of getting both sides of a 
board to have a connection.

This really only applies to things like DIP chips where one cannot 
solder under hte part.

TIA.

Dave
