Discussion on the Treatment Measures for Samples After Reliability Testing of IoT Communication Devices

Abstract

Addressing the lack of clear and actionable guidance for handling samples of IoT communication devices after reliability testing and
the numerous challenges faced in engineering practice, this paper explores treatment measures for test samples based on the practical experience of communication equipment enterprises. First, principles for identifying components that have not exceeded specified tolerance limits
but have shown signs of degradation are proposed, including focusing on components with generally low failure rates, comparing technical
indicators before and after testing, and using the ratio of the components MTBF to the single-unit test duration for assessment. Second, the
process reliability requirements for component replacement are clarified, emphasizing quality control during the replacement process, such as
component sourcing, batch consistency, and soldering processes. Finally, an acceptance procedure for refurbished equipment is established,
requiring the contractors inspection department to perform a comprehensive check in accordance with product inspection requirements to ensure product quality meets standards. By addressing these issues, this paper provides actionable guidance for handling samples after reliability
testing and offers positive support for standardizing the acceptance process of IoT communication devices.
