Cleanliness
Dense materials verified by ultrasonic flaw detection, multi-tank ultrasonic cleaning after machining, and cleanroom double-bagging so parts arrive as clean as they left the line.
Applied on vacuum-use orders
Semiconductor & Optical Equipment
Precision Machined Parts for Wafer Handling & Optical Equipment
Wafer transfer arms, vacuum chamber components, optical mounts and heat-managed base plates — machined in Dongguan, China with tolerances to ±0.005mm, ultrasonic cleaning and cleanroom double-bagging for vacuum-use parts.
Typical Components
What we machine for this class of equipment
From copper base plates for power electronics to the housings and mounts that surround a wafer or a light path.
Copper base plates & heat sinks
For power electronics and laser thermal management — copper and high-purity aluminium.
5-axis machined housings & mounts
Complex housings, lens mounts and alignment fixtures machined complete in one setup where geometry allows.
Ultrasonic cleaning & cleanroom packing
Multi-tank ultrasonic cleaning line, then cleanroom double-bagging for vacuum-use parts.
CMM verification & FAI
Coordinate measuring with datum context, FAI on the first article, 100% inspection on critical features.
Requirements
What wafer handling & optical parts actually demand
These parts are not won by a tolerance number alone. Four things decide whether a supplier survives in this class of work.
See our facility
022
Surface treatment
Matte black anodizing (sandblast + black anodize) for stray-light control, hard anodizing for moving parts like transfer arms, electroless nickel for corrosion with tight dimensional control.
Certified finishing supply chain
033
Thermal stability
Stress-relief annealing after rough machining for thin-walled geometry, and temperature-controlled machining so microns stay put during critical cuts.
±0.005mm where function needs it
044
Traceability
FAI on the first article, CMM results with datum context, CoC with material certificates, and 100% inspection records on critical features.
