All components at SST must meet strict standards and are processed through a customized cleaning system. This system's automation and process controls enable SST to achieve cleanliness consistency from batch to batch. Our standardized process includes a specialty aqueous cleaner followed by a cascade DI water rinse. This cleaning process has been used and approved by key customers like Sandia National Labs and the United States' Army. The same process can be used for precision cleaning of metals, ceramics, and glass and is suitable for UHV environments.

Lot Control

SST provides full lot control and provides a lot number with each shipment of parts. This lot number can be used to trace material certifications, equipment, operators, temperature profiles, and other valuable production data. Special services include single lot of materials and laser-marked serialization.

Customer Service

SST works closely with every customer to provide high-performing products that meet all business requirements. We can accommodate schedules and terms ranging from single prototypes to large-scale production including blanket orders and scheduled releases. Our customer service team takes pride in providing the expert care and attention our customers have come to expect from SST.
