Precision, cleanliness, and traceability for semiconductor manufacturing components. We provide tight tolerances and cleanroom-capable processes for critical wafer-handling and vacuum parts.
We combine micron-level accuracy with clean manufacturing and full traceability.
ISO-aligned inspection, SPC, and first-article reports ensure micron-level tolerances and repeatability.
5-axis milling, micro-turning, and in-process probing achieve sub-10 µm repeatability for critical features.
DFM reviews, prototype iterations, and custom fixtures speed integration with fab and OEM systems.
Lot-level traceability, material certificates, and controlled shipping meet ESD and cleanroom requirements.
Typical components we machine for fabs, equipment OEMs, and metrology systems.
CF/ISO flanges, custom electrical and fluid feedthroughs machined to vacuum and leak-rate specifications.
304L/316L stainless, Inconel, ceramic-metal assemblies
End-effectors, grippers, and robotic interface parts with tight concentricity and controlled surface finish.
7075-T6 aluminum, 6061, PEEK, stainless steel
Precision stage blocks, spindle housings, and encoder mounts with tight flatness and form control.
Aluminum alloys, hardened stainless, tool steels, Invar
We analyze semiconductor drawings with a focus on flatness, Ra, and cleanliness requirements for vacuum and wafer-handling components. Materials and tolerances are checked against fab conditions.
CNC programs and fixtures are prepared to minimize clamping marks and contamination. We also define metrology plans for tight form tolerances and surface finish checks.
Semiconductor parts are machined on high-precision equipment with in-process probing and measurement. We control micron-level tolerances and surface finishes needed for vacuum and motion stages.
Components receive electropolishing, passivation, or hard anodizing as specified. Surfaces are refined for low outgassing and easy cleaning, then pass strict inspection.
Finished components are cleaned, double-bagged or sealed as required, and labeled with full traceability information. Packaging and shipping follow your cleanroom and ESD requirements.
From Design to Prototyping to Production, RuoChen Precision turns your ideas into reality with tailored, high-end machining solutions.
We machine metals, engineered plastics, and ceramics chosen for low outgassing, thermal stability, and corrosion resistance. Finishes are specified for conductivity, cleanliness, and tight Ra requirements.
