Abstract: The present invention provides a probe apparatus, which comprises a signal transmission device, a probe, and a bottom fixing device. The signal transmission device includes a first transmission part and a second transmission part. An end of the probe is connected electrically below the second transmission part. The bottom fixing device is disposed below the signal transmission device. An end of the bottom fixing device includes a first penetrating hole and a first recess is disposed below the end. The probe passes through the first penetrating hole of the bottom fixing device. The probe is located in the first recess. The bottom fixing device reinforces the mechanical strength of the signal transmission device so that the width of the signal transmission device can be reduced. Thereby, the benefit of high-density arrangement of the probe apparatus can be achieved.

Abstract: An automatic mounting and demounting device and system for a motor testing platform, adapted to enable a control host to control automatic mounting and demounting between an axle of a motor under test and an axle of a testing apparatus, includes a mobile platform and a positional information sensing member. The control host controls the mobile platform according to positional information generated by the positional information sensing member, such that a carrier for carrying the motor under test is automatically driven to a corresponding position to thereby effect alignment and connection or separation of the axle of the motor under test and the axle of the testing apparatus. Therefore, preparation for the motor dynamics testing is automatically carried out effectively and correctly, thereby reducing the time and manpower required for testing-related preparation.

Abstract: A fixture assembly for testing a surface emitting laser diode and a testing apparatus having the same are provided. The fixture assembly comprises a base, an upper cover and a latch mechanism. The base includes at least one pocket, and at least one electrical contact interface disposed in the pocket. The upper cover includes a body, an abutting block and a pressing member disposed in the body. The abutting block is engageable with the body for slidable movement with respect to the body. The latch mechanism is disposed on the base and the upper cover, and is configured to selectively connect or disconnect the base to or from the upper cover. When the latch mechanism is operated to connect the base to the upper cover, the pocket and an opening of the abutting block form into a through cavity through which the laser diode emits the laser beam.

Abstract: A method is provided for testing a semi-finished battery cell. The semi-finished battery cell is charged with a constant current when a voltage difference between the first conductor and the second conductor is less than a voltage threshold. The semi-finished battery cell is charged with a constant voltage when the voltage difference between the first conductor and the second conductor is equal to or larger than the voltage threshold. An overall electric quantity is obtained after a default time period, wherein the overall electric quantity is an electric quantity charged to the semi-finished battery cell with the constant current during the default time period. Accordingly, an insulation related to electrodes of the semi-finished battery cell is determined as poor when the overall electric quantity is larger than an electric quantity threshold.
