The basic 6 STEPS for Photo Chemical Machining, (PCM) are as follows:
Ø CLEAN, (remove oils and other contaminates from the surface of the metal)
Ø APPLY PHOTO-RESIST, (Coat the metal with photo sensitive material)
Ø IMAGE, (Transfer the artwork image and cure the photo-resist in areas to protected from Etching) Ø DEVELOP, (Remove the non-cured photo-resist, exposing the metal in areas to be etched)
Ø ETCH, (Chemically remove the metal from areas not protected by cured photo-resist)
Ø STRIP, (Remove the photo-resist from all surfaces leaving only the etched metal)
