What i can tell you is that the vias are made my manually inserting rivets. They are soldered in and then bored open so the resulting hole is nicely round. This is a lot of work.

Joachim,

Bungard has some very nice copper rivets (from 0.6 OD to 1 OD) which already have the bores done for you.
Just need to rivet and then solder.

Tin plating cristals from various supliers
RS Part number is 567812
But normaly you may get them much cheaper somewhere else
RS prices are baad

There is also an alternative method but a kit is needed
It uses a power suply and same special electrodes and liquids
and can do silver or gold if I remember corectley it was designed to plate mobile phones and such.
I have not tried this but the tin plating cristals work fine
Just make what you need if you do not use regularly as solution losses propities with time.

EUVL, Klaus told me that his rivets are open too to start with but there can get some solder in so he bores them open so that the are nice and clean. Anyway, thanks that you seem to like what you see.

TDK has a new affordable turntable. It looks really good. In the music video you can see a woman smoking and playing a vinyl record. My kind of girl.

Joachim,

> Anyway, thanks that you seem to like what you see.

Yes, graphics design is another hobby for me, and it also shows in my PCBs.

BTW if you use Bungard photosensitive boards for prototyping, I know a trick to use the resist as solder mask.
Please email if you'd like to know more.
