Homebrew PCBs

When I worked in an electronics plant ,they had a hollow rivet they used for this. I saw many boards come back in for service where the rivet was no longer soldered to the pad. They used these where connectors were put in the board to strengthen it. I would at the very least wash the brass tubes in a mild acid to clean them and rinse well before using . lemon juice may work as I have seen it used for flux in a wave solder machine.

We were having some banter earlier this month about how to get ..what to use... for vias through 
a two sided PCB.

I found this particular tubing to be the correct size for component leads.
Your mileage may vary.

My experiments with two sided PCBs has been limited to
TWO single sided finished PCBs bolted together.
