Well, if i can get current densities that would be fine too.
I just want to know if we are talking 10ampere or 100mA here, i have
absolutely no idea.
Also i wonder which supply is needed, i mean is it necesarry to be very
stable current?
(or is a bridge with maybe a filter cap ok?)
I also wondered if it would do any good to connect the board to the anode
at the beginning.
Maybe the electrolytic action would aid in taking off the copper. of
course you can't etch
the entire board this way because there is no way of connecting it but it
takes a long
time until the first patches break free. (certainly more than half the
etch time i think).
Would this work? Can there be significant speedup expected? Would a
electrolytically aided etch
be even or not?
I think i might get titanium sheetmetal for the anode, from which i could
cut stripes
to mount to the pcb holder for connecting to the pcb if it works.
This would allow a big anode area.
I really like the idea of using a copper pipe for the cathode, it is much
cheaper...
For experimenting i will most likely use one.
