Patent ID: 6956391

Claim:
A method of testing an electronic component in which a predetermined load is set, which predetermined load is determined by a burn-in temperature, a burn-in voltage, and a burn-in period of time, and burn-in of the electronic component is carried out in such a manner that a load equal to the predetermined load is applied to the electronic component, the method comprising the steps of: a first step of placing the electronic component having a negative resistance-temperature characteristic in a heating atmosphere such that the electronic component reaches a predetermined temperature, said predetermined temperature being lower than the burn-in temperature; a second step of supplying constant current to flow through the electronic component so that the predetermined temperature of the electronic component is controlled to be increased to the burn-in temperature; and a third step of comparing the voltage actually applied to the electronic component to the burn-in voltage, correcting the burn-in time-period based on the comparison to determine a corrected burn-in time-period, and applying constant current to flow through the electronic component based on the corrected burn-in time-period.
