2

One process several Names (PCM)

• Chemical Blanking • Chemical Etching • Chemical Milling • Photo Etching • Photo Chemical Machining




3

Photo Etching is an alternative to

• Laser cut • Wire EDM• Stamping /punching


Pin holes

Flat Shield





4

Why PCM

• PCM eliminates cost of hard tooling • Stress and burr free components• Magnetic properties are un-altered • Complex components can be easily machined • Appropriate for many kind of alloys • Hard metals can be etched • Need lead time 2-3 weeks


5

Considerations

• Applications with lots of holes (mesh, screens)• Tolerances 10 to 15% of part thickness • Material up to 0.04” (1mm) thick • Part size from 0.05” X 0.05”(1.2X1.2mm) up to

18” X 18” (45X45cm)• Delivery time for first 1000PCS < 2-3 weeks
