Re: PCB through hole activation for copper plating
Hi all,
I tried it, unsuccessfully.
In my experiments, it works, but not reliably enough to be really useful.
Even getting 95% or even 99% of the vias activated is awful, because you

Re: PCB through hole activation for copper plating
I also find assembly to be a pain.? There is a house that makes the PCB and will assemble your board.? The only catch is you have to use parts in their list of 15,000 or so.? That may be too

Re: Videos
It looks you could use benefits of PCB's ability to do clearance and
connectivity checking.
See if you can use gEDA schematics. If not, see if you can use PCB directly.
