Semiconductor capital equipment and high-end electronics punish anything that drifts out of spec. Wafer-handling arms swing through 10 million cycles a year; vacuum chambers cannot outgas; optics stages cannot deflect under their own load. We machine for that environment — and we know the audit trail it demands, from raw-material lot number through final package inspection.
Materials and tolerances
For vacuum and cleanroom service we default to 316L VAR-grade stainless, electropolished to Ra 0.4 µm on sealing faces. Aluminum 7075 handles structural pieces where weight matters. We routinely hit ±0.005 mm on critical locating features and ±0.01 mm on through-holes for dowel alignment. For ultra-stable optics stages we work in Zerodur and superinvar when the thermal coefficient of expansion is the governing spec, and we can hold CTE-matched assemblies across the operating temperature range.
Cleanliness and documentation
Parts ship double-bagged with lot-level traceability. Each batch is accompanied by material certs, surface-finish readings, and a CMM report on first articles. When your installation needs ISO Class 3 cleanroom compatibility, we adjust packaging and cleaning to match. We can also perform residual particle counts (per ISO 14644) and Helium leak testing on vacuum components before shipping.
Traceability chain
From raw-material lot number through machined part, first-article inspection and packaging — every step is documented in a traveler that drops into your FAI package. For fab-tool suppliers we support SECS/GEM data collection, including in-process measurement logging and tool-offset records. We maintain a 10-year document archive per project so your procurement team can re-order without re-qualification.
