While I'll admit Markus's plating system is a piece of working art, to do plated holes you do not have to be so talented in design and fabrication. A simple 2-5 Gallon plastic bucket, two copper anodes, A power supply, (could be as simple as a car battery charger) and some way to regulate the power( could be a simple as a lamp dimmer) You could use two anodes, or just one (but you'd have to flip the board)
In my tank, the anodes (4X6) are not as big as the pcb(6X9), and this does not matter as much as copper is plated out of the solution, more than it is directly from the anodes - I also have a larger distance between the pcb and anodes.
The kit from Caswell includes 2 buckets, heater, anodes, cleaning and plating chems. It works very well with the ink, and less than $200 for a complete but- minimal system.

That is what I was trying to say to Ballendo. the 'brain trust' on
this board peaks in the 'making PCB's area and is THE place to get
ansers when you want to make PCB's.
And yes, Markus holds the bar very high for the rest of us !
I just wish he were close by my area.
There is a NJ robotics society and one of the guys and a laser board
etcher. about 4 ft cube. Wanna talk about envy ? Problem for me is
that he is too far away....
Oh, may I respectfully request that you keep your questions on the
open list and not in personal e-mails? the rest of us would like to
listen in.
