Abstract:
In a system and method for automated testing of optical characteristics of a light-emitting element, an optical characteristic capturing device continuously rotate about the light-emitting element to be tested at a fixed radius while constantly facing the light-emitting element. The path of rotation is divided into a measuring section and a non-measuring section. The non-measuring section is utilized to enable rotation of the element to be tested or replacement of the element to be tested, thereby simplifying operational states of a support device of the capturing device. Not only can this work with an automated process to perform continuous testing of elements, the overall structure of the testing system can be simplified, and the operation there of can be sped up. Besides, measurement of wide angles can be conducted with accuracy. Thus, the marketplace's requirement for an instrument for high-speed testing of light-emitting elements can be fully met.

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.

An anti-overturning device for cabinet and its cabinet structure is disclosed in the present invention. The anti-overturning device comprises a first fixing member, a second fixing component and a connecting part. The first fixing component is used for arranging detachably on the outside of the cabinet bottom. The second fixing component includes at least a second opening, and the second opening is used for fixing on the auxiliary wheel or on the ground. The anti-overturning devices are provided evenly on the periphery of the cabinet bottom. The anti-overturning devices change the horizontal position of the original overturning pivot of the cabinet and enlarge the overturning angle to prevent from overturning the cabinet.
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.
