Publication number: 20250040095Abstract: A phase-change temperature regulating system and an electronic device testing apparatus and method are described. In an embodiment, the system uses a temperature regulating fluid chamber containing a temperature regulating fluid to allow the temperature regulating fluid to cover at least a part of at least one surface of an electronic component. When a temperature of the electronic component reaches a boiling point of the temperature regulating fluid, the temperature regulating fluid becomes steam through a phase change to transfer heat energy outward from the electronic component, and condenses on an inner surface of the fluid chamber to further transfer heat energy of the steam to a temperature-regulating apparatus. The condensed temperature regulating fluid flows back to the temperature regulating fluid, thereby continuously circulating.Type: ApplicationFiled: May 10, 2024Publication date: January 30, 2025Applicant: CHROMA ATE INC.Inventors: Xin-Yi Wu, Yu-Wei Chuang, I-Ching Tsai

Publication number: 20240192268Abstract: A multiphase thermal interface component, a method of forming the same, and an electronic device testing apparatus provided with the same are provided. The multiphase thermal interface component includes a thermal interface solid element and a thermal interface fluid material. The thermal conductive surface of the thermal interface solid element has an accommodation space, and the thermal interface fluid material is accommodated in the accommodation space. Therefore, the multiphase thermal interface component combines solid-phase and fluid-phase thermal interface materials. Since fluids have the properties of changing shape, flowing, and splitting arbitrarily, the thermal interface fluid material can completely fill up the air gaps between the thermal interface solid element and the thermal control device/the temperature-controlled component, so that the full surface temperature control of the contact interface can be achieved, thereby effectively improving the thermal conduction performance.Type: ApplicationFiled: November 16, 2023Publication date: June 13, 2024Applicant: CHROMA ATE INC.Inventors: Yu-Wei Chuang, Xin-Yi Wu, Jui-Che Chou

Patent number: 11567113Abstract: The present invention discloses an AC impedance measurement circuit with a calibration function, which is characterized in that only one calibration impedance is needed, associated with a switch circuit. Based on the measurement results of the two calibration modes, an equivalent impedance of the switch circuit, circuit gain and phase offset can be calculated. Based on the above results, the equivalent impedance of the internal circuit is deducted from the measurement result of the measurement mode to accurately calculate an AC conductance and a phase of the AC conductance for impedance to be measured. In addition, by adjusting a phase difference between an input sine wave signal and a sampling clock signal, impedance of the same phase and impedance of the quadrature phase can be obtained, respectively, and the AC impedance and phase angle of the impedance to be measured can be calculated.Type: GrantFiled: October 28, 2021Date of Patent: January 31, 2023Assignee: Hycon Technology CorporationInventors: Po-Yin Chao, Shui-Chu Lee, Yu-Wei Chuang
