Homebrew PCBs

Hi Bryan,

My interest here is in being able to make few-at-a-time spring contacts and such for proof of concept design work; definitely small
quantity, hobby level/grade work. It will likely be a week or two  before I can start on this project; so if you're not
time-constrained, and wish to send your artwork for experimental purposes, that will be fine. Should this trial work out reasonably
well, and you wish to have some quantity that I can manage made, then you can send material for that at that time.

Regards,

Roger

Any interest in testing this on the parts I am looking for?  I'll provide material and artwork!!

Thanks for your consideration, Bryan

Thanks for the offer DJ, I appreciate that.

I will just order a few phosphor bronze sheets and build a CuCl solution, and get with the program to see what it takes.

Thanks,

Roger

I suspect the process is the same, along with undercutting etc,
although the chemistry might have to change. Brass works with PCB
techniques because the brass reacts to etchant the same as copper
does.

Bronze is still a copper alloy, it might react the same too. If you
want to mail me a small piece(like, 0.5" sq or smaller, doesn't take
much), I can dip it in the CuCl etchant and see what it does.
