I loved doing my job at EIT - chemical etch... I could etch
BOTH SIDES of a 6oz copper panel in less than 2 mins LOL.
Then again, I used 13 spray bars equally distributing 30-60GPM of Cupric Chloride at 80+PSI. Oh - I had two etch chambers... so that's 26 spray bars... pfffft. :P
The etch machine I used was exactly as large and deadly as Oprah... only it smelled better. (Catch of a whiff of the fumes from Cupric Chloride... you'll see
)
