Stainless Steel SUS400 CNC Machining Parts For Semiconductor Testing Equipment

Stainless Steel SUS400 CNC Machining Parts For Semiconductor Testing Equipment


Product Overview:

This product is made of martensitic stainless steel SUS400, through high-precision CNC machining technology, designed for semiconductor test equipment (such as probe stations, sorting machines, test sockets, etc.) designed for precision structural components. With high hardness, corrosion resistance, low particle precipitation and other characteristics, to meet the semiconductor test environment on the material stability and cleanliness of the stringent requirements.


Product Details

CNC Machining Aspect Specific Application in Semiconductor Testing Equipment Parts Technical Details & Benefits
Material Machining Machining SUS400 series stainless steel (e.g., SUS410, SUS430) for components like probe holders, microfluidic fixtures, and sensor mounts. - High hardness (170–210 HB) of SUS400 requires carbide or ceramic tooling.
- Coolant-controlled machining prevents work-hardening and thermal distortion.
Precision Geometry Creating complex internal features (e.g., micro-channels, probe slots, threaded holes) and ultra-fine external profiles. - Tolerances as tight as ±0.005 mm for critical dimensions (e.g., probe alignment holes).
- Five-axis CNC enables multi-angle machining without re-clamping.
Surface Finish Optimization Achieving mirror polish (Ra ≤ 0.2 μm) on fluid contact surfaces and low-roughness exteriors to minimize particle adhesion. - Diamond-tipped end mills for finish machining.
- Electrolytic polishing (EP) post-CNC to refine surface texture and meet ISO 14644-1 Class 5 cleanliness standards.


Core features
