CNC machine to mill out the PCB; no more messy chemicals!
In my first year out of Uni when I was designing
instrumentation amplifiers in the research dept of the
CEGB and well before the days of anal H&S, in order to
get the PCB etch to go a bit faster, we had a Baby Belling
cooker and we'd boil up the ferric chloride in a saucepan.
