By fully serializing boards, the system automates component level traceability – down to the reference designator – for all components and assembly steps, even in a multi-vendor, multi-technology environment. This comprehensive approach encompasses SMT (Surface Mount Technology) machines, PTH (Pin Through Hole) machines, manual stations, rework stations, and box build stations, leaving no traceability gaps. Temperature, humidity, oven profiles, and other process variables can even be monitored and logged to provide process traceability. This system can be used with or without the Lean Manufacturing modules, delivering on the pay as you grow approach of the Optel system.
