Dual-Stage Temperature Adjustment System for Electronic Component Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature adjustment systems for device under test (DUT) require a large amount of energy when there is a significant difference between the initial air temperature and the target temperature.
Innovation Solution
A dual-stage temperature adjustment system that includes a first device to supply temperature-adjusted fluid directly to the socket or contact member of the DUT and a second device to adjust the chamber atmosphere temperature, utilizing a heat exchanger to exchange heat between the fluid and the chamber atmosphere, thereby optimizing energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a large amount of energy is supplied to adjust the temperature of air from a large difference between initial temperature and target temperature, then the temperature adjustment capability is improved, but the energy consumption increases significantly
Solution Approach 1:
The system performs preliminary temperature adjustment by circulating air through the chamber atmosphere before supplying it to the DUT. This preliminary action pre-heats or pre-cools the air using the chamber atmosphere, reducing the energy required for subsequent temperature adjustment of the DUT.
Solution Approach 2:
The chamber atmosphere acts as an intermediary medium between the temperature control system and the DUT. Instead of directly heating or cooling the air supplied to the DUT, the system uses the chamber atmosphere as a heat exchange medium, which reduces energy consumption by leveraging the existing thermal environment.
2Speed
If air is directly supplied to the DUT without utilizing chamber atmosphere heat, then the temperature control speed is improved, but the energy efficiency deteriorates
Solution Approach 1:
The system maintains continuous circulation of air through the chamber atmosphere, ensuring that the heat exchange process occurs continuously rather than intermittently. This continuous action allows for efficient energy utilization while maintaining effective temperature control of the DUT.
Solution Approach 2:
The chamber atmosphere serves itself as a heat source or heat sink for the air circulation system. The system leverages the existing thermal energy in the chamber atmosphere to adjust the temperature of supplied air, reducing the need for external heating or cooling energy input.

AI summary
A temperature adjustment system for adjusting a temperature of a DUT electrically connected to a socket includes a first temperature adjustment device that supplies a fluid to an internal space in either the socket or a contact member that contacts the DUT when the DUT is pressed against the socket and a second temperature adjustment device that adjusts a temperature of an atmosphere in a chamber in which the socket and the contact member are disposed. The first temperature adjustment device includes a first supplier that supplies a first fluid and includes one or more connectors connected to one or more supply sources that supply the first fluid and a heat exchanger disposed between the one or more connectors and the internal space. The heat exchanger has a heat exchange part exposed in the chamber and exchanges heat between the first fluid and the atmosphere in the chamber.
