Reliability Testing Overview
Reliability Testing
SUNMATE has established a comprehensive reliability verification system covering three key stages: incoming material reliability, in-process reliability, and finished product reliability. All products must pass rigorous reliability testing prior to shipment, ensuring long-term stable operation under customer application conditions.
Testing Standards
JESD22 series standards
AEC-Q101 automotive-grade standard
MIL-STD-883 military-grade standard
Customer-specific requirements
