It provides R&D, 3D software design, ODM, OEM, SDK, and sample-based customization services, with new products reported in the past year. Production and quality evidence includes inventory capability, raw-material traceability, 100% finished-product inspection, ERP-based process management, and stated quality, complaint-handling, and corrective-action procedures.
