Abstract
A heater drive controlling apparatus for an electronic component testing apparatus includes a breaker disposed between a power source and heaters, and a controller that controls electric currents supplied from the power source to the heaters in order according to a first priority set for the heaters such that a sum of the supplied electric currents is within a rated current of the breaker. The electronic component testing apparatus includes a test chamber, a thermal-stress applying chamber, and a thermal-stress removing chamber each of which includes the heaters.
Claims8
A heater drive controlling apparatus for an electronic component testing apparatus comprising:
- a breaker disposed between a power source and heaters;
- and
- a controller that controls electric currents supplied from the power source to the heaters in order according to a first priority set for the heaters such that a sum of the supplied electric currents is within a rated current of the breaker, wherein
- the electronic component testing apparatus includes a test chamber, a thermal-stress applying chamber, and a thermal-stress removing chamber each of which includes the heaters, and
- the controller:
- controls the heaters in a cycle,
- compares the rated current with a sum of line currents calculated from a power of the heaters to be turned on in the cycle, and
- controls the supplied electric currents in response to determining that the sum of the line currents is greater than the rated current.

- a breaker disposed between a power source and heaters;
- and
- a controller that controls electric currents supplied from the power source to the heaters in order according to a first priority set for the heaters such that a sum of the supplied electric currents is within a rated current of the breaker, wherein
- the electronic component testing apparatus includes a test chamber, a thermal-stress applying chamber, and a thermal-stress removing chamber each of which includes the heaters, and
- the first priority is set based on a second priority set for each of the test chamber, the thermal-stress applying chamber, and the thermal-stress removing chamber.

- the heaters comprise:
- a first heater;
- and
- a second heater having the first priority set lower than the first priority of the first heater, and
- the controller supplies a first electric current of the electric currents to the first heater, then reduces the first electric current supplied to the first heater, and then supplies a second electric current of the electric currents to the second heater.
