At Xinda, we believe that by always providing products that meet or exceed your quality requirements, we earn your continued trust as a reliable partner for EMS. We use a rigorous quality management system (QMS) to control the entire production process to ensure the quality of each assembly level.


Utilizing our proprietary tracking system, Xinda operates a rigorous five-stage quality control system that includes:
