DIY through hole plating of PCBs


Jan Mrázek documented his experience experimenting with DIY through-hole plating of PCBs:

I’ve been thinking about though hole plating for several years. The general procedure is simple – you have to activate non-copper surfaces (make them conductive) and then you apply standard electroplating procedure. You can find many tutorials on the internet, however, most of the require hard-to-get chemicals for the activation solution. Few weeks ago, I noticed that the local electronic component supplier had started to sell Kontakt Chemie Graphit – a conductive paint. It’s basically a colloidal graphite in an organic solution. It is supposed to be used for making surfaces conductive to prevent static electricity discharges. This could be perfect for activation of the non-copper surfaces! So I gathered all the necesery chemicals and equipment and made a test run.
