Say hello to my #PCB manufacturing lab. Here is the 3D printer showering the board in purple rays.
In those bottles live the necessary chemicals. Neutralize before disposing!
They go to trays where the board takes a bath. First, a minute in NaOH to develop, then (after a rinse in water), 20min of persulfate to etch away the copper. The big bowl holds warm water.
