Testing and Screening
STE International partners with several independent test labs which allow us to offer a broad spectrum of value added testing services. Our value added testing and screening capabilities are frequently used to ensure only quality tested products are distributed. Common uses include:
- Obsolescence of mil spec devices
- Customer drawing requirements specify selected parameters
- Re-screening requirements
- Concern over influx of counterfeit parts from China
