I have no copper circuit boards and no ferric chloride and no Hydrochloric acid. I have not found a circuit board etch kit yet. I did fine copper boards on ebay from china it takes a month to get them.
Someone on ebay has old Radio Shack etch kit with no information, it does not tell if its and empty box or there is something inside the box. No reply from seller yet. Might be vintage collectors item.
Last time I used an etch kit 35 years ago ferric chloride when through the black ink ate holes in the copper traces. 35 years later has technology gotten better I want something that works good?
