FIELD: radio equipment manufacturing; monitoring of integrated circuits.
SUBSTANCE: temperature -20°C or -28°C is established in cold chamber, integrated circuits are loaded, leakage current of every circuit is measured. Temperature is reduced down to -28°C or increased up to -20°C with the rate of not more than 10°C with continuous measurement of leakage current. If leakage current value does not increase sharply, then content in under-casing volume of integrated circuit will correspond to requirements of general technical conditions, i.e. will not exceed 0.05 volume percent at normal temperature.
EFFECT: expansion of monitoring functional resources.
