What Makes a CNC Company Suitable for Semiconductor Equipment Parts?
Before reviewing suppliers, it’s important to understand the selection criteria specific to semiconductor applications:
- Ultra-tight tolerances (±0.005 mm or better)
- Experience with aluminum 6061/7075, stainless steel 316L, PEEK, ceramics
- Surface finishing expertise (anodizing, electropolishing, passivation)
- Cleanroom-compatible manufacturing
- Vacuum-compatible component experience
- Stable quality systems (ISO 9001 or equivalent)
Suppliers lacking semiconductor-specific experience often struggle with contamination control, documentation standards, and repeatability.
