Homebrew PCBs

It does not short two tracks, but adds a high value of resistance between the tracks, more of a problem on low power digital and analogue systems.

I don't suffer from insanity I enjoy it!

I am not a very "analog" guy because I think in terms of "short" or 

"open". What do you mean exactly here? Is the tinning "shorting" tracks?



My question at this point: we saw it works of a "solid" PCB, but how 

good is it on an etched circuit?
