The shelf life mainly depends on factors such as the materials used, manufacturing conditions, the moisture barrier bags used for packaging, the amount of desiccant used, and storage conditions.

SGMICRO regularly selects various products stored for three years and five years or longer for comprehensive verification. No abnormalities have been found in these products stored under normal conditions. The selected products cover different package types, package structures, production sites, material types, and moisture sensitivity levels. Verification conditions include the ESD capability of packaging materials, carrier tape adhesion, product appearance, solder ability, electrical performance, and reliability.
