    • A loader of semiconductor package burn-in test equipment allows a test socket to be commonly used for semiconductor packages of all sizes. The loader includes a vacuum suction head for picking semiconductor packages to be tested, and a package guider for ensuring that semiconductor packages of any size will be aligned with the test socket. As the semiconductor package is positioned over the test socket by the vacuum suction head of the loader, guide surfaces of the package guider are brought inwardly into guide positions at which the surfaces extend just beneath the vacuum suction head. Any semiconductor package that is not in alignment with the test socket while being held by the vacuum suction head is guided by the guides surfaces into alignment once the vacuum suction is turned off and the package falls from the vacuum suction head. Thus, the package guider serves as an adaptor, eliminating the need for several test sockets having respective adaptors for different sizes of semiconductor packages.
    • 半导体封装老化测试设备的装载机允许测试插座常用于各种尺寸的半导体封装。 装载机包括用于拾取待测试的半导体封装的真空吸头,以及用于确保任何尺寸的半导体封装将与测试插座对准的封装导向器。 当半导体封装通过装载机的真空吸头位于测试插座上方时,封装引导件的引导表面向内进入引导位置,在该位置处表面正好在真空抽吸头的正下方延伸。 在真空抽吸被关闭并且包装从真空抽吸头落下的情况下,由真空吸头保持的不与测试插座对准的任何半导体封装被引导面对引导。 因此,封装导向器用作适配器,消除了对具有用于不同尺寸的半导体封装的相应适配器的多个测试插座的需要。

    • When high speed memory devices are tested using a tester having a lower operating frequency than the operational speed of the memory device, limit conditions for the tester signals are required to prevent the interference between the tester and device signals. The present invention provides the limit conditions for the shift and strobe signal. The strobe signal is delivered to comparators with a delivery delay time defining the dead time zone. The shift signal controls the data path of the device to and from a driver and a comparator. When the strobe signal is within the present test cycle, the shift signal of a read cycle must be activated at the same time or earlier than the activation time of the WE/ signal of the next write cycle and the shift signal of a write cycle must start at the same time or earlier than the activation time of the OE/ signal of the next read cycle. When the strobe signal is outside of the test cycle, the shift signal must meet prescribed maximum and minimum timing conditions.

    • A plasma display panel apparatus includes a pair of discharge sustaining electrodes, a panel capacitor to supply charged voltage alternately to each electrode of the pair of discharge sustaining electrodes, a switching device for discharge that is turned on when the panel capacitor is discharged, to thereby pass through discharged current of the panel capacitor, a current sensing part to sense the current passed through by the switching device for discharge, and an over-current controlling part that turns off the switching device for discharge when the current sensed in the current sensing part is at or above a predetermined reference value. With this configuration, the plasma display panel apparatus protects the switching device from over-current generated during an abnormal driving of the discharge sustaining electrode driving circuit.

    • A method for testing semiconductor devices includes loading a customer tray with semiconductor devices to be tested. Groups of devices are transferred from the customer tray to buffer trays for testing. The number of devices in the customer tray is checked after each transfer. If the customer tray is empty, the number of semiconductor devices in the buffer trays is counted and compared with the number of semiconductor devices that can be tested simultaneously, typically either 64 or 128. If the number of semiconductor devices in the buffer trays is greater than the tester capacity, the semiconductor devices in at least one buffer tray are tested. If the number of semiconductor devices in the buffer trays is smaller than the tester capacity, semiconductor devices that were determined to be low quality in a prior test are loaded into a buffer tray, thus testing both untested and low quality devices together.
    • 一种用于测试半导体器件的方法包括:将客户托盘加载到待测试的半导体器件上。 设备组从客户托盘传输到缓冲盘进行测试。 客户托盘中的设备数量在每次传输后都会被检查。 如果客户托盘为空,则对缓冲托盘中的半导体器件的数量进行计数,并与可同时测试的半导体器件的数量进行比较,通常为64或128.如果缓冲托盘中的半导体器件的数量较大 比测试器的容量,测试至少一个缓冲盘中的半导体器件。 如果缓冲盘中的半导体器件的数量小于测试器容量,则在先前测试中被确定为低质量的半导体器件被加载到缓冲托盘中,从而同时测试未测试的和低质量的器件。
