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.
Abstract:
Increase in number of valves complicates the configuration and control. A temperature control apparatus for controlling a temperature of a device, includes; a heat exchange section exchanging heat with the device; a main flow path causing a fluid to flow; a sub flow path causing, to flow, a fluid having a temperature different from a temperature of the fluid flowing through the main flow path; a mixture flow path merging the fluids from the main flow path and the sub flow path and causing the merged fluids to flow to the heat exchange section; and a flow rate adjusting section adjusting an amount of a fluid flowing from the sub flow path to the mixture flow path, in relation to the fluid flowing through the main flow path.
Abstract:
An electronic component handling apparatus for handling a DUT and pressing the DUT against a socket electrically connected to a tester, including: a temperature adjuster adjusting a temperature of the DUT; a first calculator calculating the temperature of the DUT on the basis of a detection result of a temperature detection circuit disposed in the DUT; a temperature controller controlling the temperature adjuster; and a first controller outputting a first signal to the temperature controller. A temperature control includes a first temperature control based on the temperature of the DUT calculated by the first calculator and a second temperature control, and when the first signal is input from the first controller to the temperature controller after the temperature controller starts the first temperature control, the temperature controller switches the temperature control from the first temperature control to the second temperature control.
Abstract:
[Object] Provided is an electronic component handling apparatus capable of controlling a DUT temperature within an appropriate range even in a DUT in which an abrupt temperature change occurs under test.[Solving Means] An electronic component handling apparatus 50 includes a temperature adjuster 70 which adjusts a temperature of a DUT 90, a first calculator 86 which calculates the temperature of the DUT 90 on the basis of a detection result of a temperature detection circuit 92, a temperature controller 87 which controls the temperature adjuster 70, and a first controller 88 which outputs a first signal S1 to the temperature controller 87, in which a temperature control performed by the temperature controller 87 includes a first temperature control based on the temperature of the DUT 90 calculated by the first calculator 86 and a second temperature control different from the first temperature control and the temperature controller 87 switches the temperature control of the DUT 90 from the first temperature control to the second temperature control when the first signal S is input from the first controller 88 after the first temperature control starts.
