Abstract: A test apparatus includes a test site, a buffer carrying device, a transport carrying device, a handling mechanism and a dry air flow guide mechanism. The test site performs a test procedure on the objects. The buffer carrying device is disposed close to a side of the test site, holds the objects and performs a temperature conditioning process. The transport carrying device is disposed close to another side of the test site, moves back and forth along a transporting direction, transports the objects into and out of the test site, and heats up the objects. The handling mechanism carries the objects among the buffer carrying device, the test site and the transport carrying device. The dry air flow guide mechanism guides a dry air to surround the test site, the buffer carrying device, the transport carrying device and the handling mechanism and generates a dry environment to prevent dew condensation.

Abstract: An image capturing device includes a cube prism and three image capturing units. The cube prism includes an incident surface, a first exiting surface, a second exiting surface, and a third exiting surface orthogonal to each other, and further includes a first splitting surface, a second splitting surface, a third splitting surface, and a forth splitting surface orthogonal to each other. The light incident into the incident surface is split by the four splitting surfaces into monochromatic lights, and the monochromatic lights respectively exit from the three exiting surfaces to be received by the image capturing units to form images. The images can be combined as a multicolored image. Accordingly, the light-use efficiency and the image resolution can be improved, and the color fault of the image can be avoided.

Abstract: The present invention provides an AC power supply capable of programming output impedance and a method for simulating output impedance. The method comprises the following steps. The simulating command, selectively provided by a control circuit, is associated with a voltage adjustment value and a phase adjustment value of a test circuit (S20). The control circuit calculates the voltage adjustment value and a preset voltage value to form a voltage command (S22), and calculates the phase adjustment value and a preset phase value to form a phase command (S24). A power supply circuit generates a simulated output voltage according to the voltage command and the phase command. The preset voltage value and the preset phase value are related to a preset output voltage provided by the power supply circuit, and the simulated output voltage is a simulation of the preset output voltage, provided by the power supply circuit, passed through the test circuit (S26).

Abstract: The present invention relates to an aging test system and an aging test method for a thermal interface material and an electronic device testing apparatus having the system, wherein a controller controls a movable carrier to move to a high temperature generating device so that the thermal interface material on the movable carrier is brought into contact with the high temperature generating device; the controller further controls a temperature sensor to detect the temperature of the thermal interface material; the controller compares an output temperature datum of the high temperature generating device with a temperature measurement datum detected by the temperature sensor. Accordingly, the thermal conductivity of the thermal interface material can be obtained for immediately determining the quality and the performance degradation of the thermal interface material, which can be used as a reference for selection or replacement of the thermal interface material.

Abstract: An automated optical measurement system and method for a near eye display are provided. A controller first controls the near eye display to display a specific pattern, then controls a displacement generation module to drive an image sensing module toward or away from an imaging module, and controls the image sensing module to capture the specific pattern to obtain focus images; and the controller performs focusing according to the focus images. Finally, the controller measures an optical characteristic of the near eye display. Accordingly, the focusing method used is to capture the specific pattern displayed by the near eye display while moving the image sensing module, and perform automatic focusing by comparing the capture results.

Abstract: The present invention relates to a chip-fixing device for a socket, which comprises a fixing base body and a movable stop. The socket is assembled in a socket-accommodating recess of the fixing base body. The movable stop is assembled in the fixing base body and controlled in such a manner that a stopper is moved between a first position and a second position, wherein the first position refers to a position where the stopper is located right above the socket, and the second position refers to a position where the stopper is not located right above the socket. Accordingly, the socket-accommodating recess can be used to install sockets of different sizes, and the movable stop can drive the stopper to restrict a chip from falling off the socket or drive the stopper to release the chip, depending on presence or absence of an external force.

Abstract: A wafer inspection system includes a carrier device, a probe card, a first metal kit and a surround separating unit. The probe card includes a detection portion and a conductive layer surrounding the detection portion and configured at a bottom surface of the probe card. The first metal kit is configured at a bottom portion of the probe card and coupled to the conductive layer and includes a first window and a first ring piece extending from a periphery of the first window. The first window is for the detection portion to extend out. The surround separating unit is configured as an electrically conductive wraparound unit surrounding and laterally enclosing the detection portion and a wafer to be inspected when the probe card performs a probe procedure on the wafer to be inspected. Thus, a probe procedure of the detection portion and the wafer to be inspected can be performed in an environment shielded from external noise or interference sources, thereby improving inspection accuracy.

Abstract: 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.
