  • Patent number: 12158493
    Abstract: A wafer inspection system includes probe and supporting devices opposite to each other. The probe device includes a probe and an electrically conductive module for transmitting test signal of a driver IC. The supporting device includes a chuck, an annular elastic module detachably disposed on the chuck, and a carrier. The chuck has a supporting portion located correspondingly to a hollow portion of the annular elastic module, which is larger than or equal to the carrier in size on an imaginary horizontal plane, enabling the carrier carrying a wafer to be placed on the supporting portion to be electrically connected with the annular elastic module. When the wafer is contacted by the probe, the electrically conductive module is abutted against the annular elastic module to form a short-path test loop. As a result, it is convenient to pick and place the carrier and wafer, enhancing inspection efficiency.

  • Publication number: 20240321321
    Abstract: A data processing device includes a base plate and an electronic module. The base plate includes N driving portions. The electronic module includes an electronic component, a tray and a recognition mechanism. The tray is configured to support the electronic component and includes N slots. The tray is disposed on the base plate, such that an i-th driving portion of the N driving portions is disposed in an i-th slot of the N slots. The recognition mechanism is disposed on the tray. The recognition mechanism includes N interfering portions and N receiving recesses. When the tray moves with respect to the base plate toward a first direction, the i-th driving portion moves within the i-th slot toward a second direction to push an i-th interfering portion of the N interfering portions to move, such that the i-th interfering portion extends into an i-th receiving recess of the N receiving recesses.

  • Publication number: 20240279962
    Abstract: A device with lock function includes a housing, a casing and a lock mechanism. The housing has a first engaging portion. The lock mechanism includes a frame, a lock member, a first elastic member, an operating member and an unlock member. The frame has a second engaging portion. The lock member has a third engaging portion engaging with the first engaging portion to lock the casing in the housing. The unlock member has a fourth engaging portion engaging with the second engaging portion to restrain the operating member. When the unlock member is pressed, the fourth engaging portion disengages from the second engaging portion and the first elastic member drives the lock member to move toward an inside of the frame, such that the third engaging portion disengages from the first engaging portion and the lock member drives the operating member to move toward an outside of the frame.

  • Publication number: 20240272696
    Abstract: An electronic device and a performance optimization method thereof are provided. The electronic device includes a battery module, a processor and a controller. The battery module is configured to supply power to the electronic device. The processor has a power consumption limit. In a power connection state, the controller determines whether to disable a power consumption limit adjustment function of the processor according to a source power provided by a power adapter and a system performance use setting of the electronic device. When the power consumption limit adjustment function is disabled, the processor executes an application program to monitor a storage capacity of the battery module and adjusts the system performance usage setting according to the storage capacity.
