Homebrew_PCBs

HI all , I have a supply of fr-4 pieces left over when a local pc
shop closed mostly double side copper clad most are .045 and .062 e-
mail me with the size you need for your projects and a fair price per
piece by square inch and i'll see what I got to fit your needs. I
really enjoy this groups posts and have learned a lot from you all.
thanks and keep up the good work. I read in an australian hobby book
that attaching a carbon rod with a wire to the board being etched in
CUCL H202 would speed up the process by creating an ionic situation
like a battery. wonder if anyone has sucess with that. thanks Luther

hi luther, did they write about connecting a battery / psu between the two
electrodes
or simply using the different electrochemical voltages?

i guess this will only work as long as the copper is one area (when the
edges are removed first it may be hart to connect the wire).

i would very appreciate to hear more from this, i will try it maybe next
time...

but only because of interest, i think it is fast enough as it is...



but maybe hart to compare results... maybe 2 boards needed, one on the
wire, the other conventional, in the same etchant
at the same time....

regards
stefan
