Abstract: A dew resistant module for a test socket, and an electronic component testing device having the same are provided. An enclosure body is provided to circumscribe the test socket; and a test socket base plate provided on top of the test socket and enclosure body. A cover is provided to cover the test socket, enclosure body and test socket base plate. With the provision of the enclosure body and the cover, the test socket, test socket base plate and a portion of the thermal head are prevented from coming into contact directly with the atmosphere, whereby condensation or dewing is prevented, thermal insulation achieved and energy consumption minimized.

Abstract: A dual loop type temperature control module and an electronic device testing apparatus having the same are provided. The temperature control module comprises a first loop through which a first working fluid of a first temperature flows, a second loop through which a second working fluid of a second temperature flows, a controller for controlling a first switching valve such that the first or second working fluid flows through a temperature regulating device, and a second switching valve such that the working fluid flowing through the temperature regulating device returns to the first or second loop. The temperature regulating device adjusts a thermoelectric cooling device to reach two different reference temperatures based on the rise/fall of its temperature dependent on the working fluid. The thermoelectric cooling device regulates the temperature of the tested object under a wide range of temperature difference and with accuracy based on the reference temperatures to facilitate the detection of high/low temperature.
