Pin holes
Flat Shield
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

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
