At this time, since the seating part 100 is connected to the heat dissipation member 120, heat generated in the substrate 10 in the seating area 110 may be radiated to the outside more than a predetermined level.

However, if a problem such as the temperature of the chamber 700 is higher or lower than a predetermined temperature occurs, since the normal burn-in test cannot be performed, in this case, the controller 530 uses the alarm generator 550. Alarm can be triggered externally.

In addition, the controller 530 may display the measured temperature and the preset temperature to the outside in real time by using the indicator 540, so that the operator can always check.

At this time, the current supply detector 520 detects the current supply at the contact point P of the substrate 10 and transmits a signal thereof to the controller 530.

In addition, the controller 530 blows the heating air of a predetermined temperature into the chamber 7000 using the blow unit 600. Here, the blow unit 600 includes a fan 610 and a heater 620 for heating the outside air. Therefore, the outside air heated by the heater 620 is supplied into the chamber 700 by the fan 610. In addition, the air supplied into the chamber 700 is discharged through a hole circulated to the upper portion of the chamber 700. Thus, the heated air may have a constant flow in the chamber 700.

In addition, the temperature sensor 510 installed in the chamber 700 measures the internal temperature of the chamber 700 and transmits the measured temperature to the controller 530. The controller 530 may determine whether the measured temperature is a predetermined temperature, and the internal temperature of the chamber 700 is a predetermined temperature, for example, 120 degrees Celsius, using the blow unit 600. The state is maintained for a preset time.

Accordingly, the substrate 10 on which the LED 11 is mounted is exposed to a predetermined temperature in a state of being seated on the seating portion 100 ″, and thus, the substrate 10 and the LEDs 11 may be exposed to the substrate 10. Burn-in test can be performed at a constant temperature on the junction surface of.

However, if a problem such as the temperature of the chamber 700 is higher or lower than a predetermined temperature occurs, since the normal burn-in test cannot be performed, in this case, the controller 530 uses the alarm generator 550. Alarm can be triggered externally.

In addition, the controller 530 may display the measured temperature and the preset temperature to the outside in real time by using the indicator 540, so that the operator can always check.
