Abstract: The present invention relates to a locking mechanism for a press head, and an electronic device testing apparatus comprising the same, wherein a slider and a locking pin are disposed on the press head and a test socket substrate, respectively. When the press head is moved and engaged with the test socket substrate, an actuator drives the slider to secure the locking pin, so as to secure the press head and the test socket substrate and prevent the press head and the test socket substrate from being separated from each other. The mechanism is simple in construction, easy to install and maintain, reliable, and can be integrated into the support arms, and occupies a relatively small space. Energy is consumed only when the actuator is actuated to effect locking or unlocking. That is, only when the slider is driven and moved, energy is consumed. No extra energy is needed to persistently press down or drive the locking mechanism.

Abstract: A position calibration system and method are disclosed, in which a control unit is provided to control a positioner sensing module to scan a circular positioner provided on a positioning substrate in a first direction and a second direction so as to acquire midpoints of two scanned line segments and acquire an intersection of lines extending from the two center points in a direction perpendicular to the first and the second directions as a calibration reference point, which correspond to a centroid (a center) of the circular positioner. The calibration reference point functions as a reference point for positioning the positioning substrate with respect to the positioner sensing module and is stored in a memory unit. The calibration reference point can be used as a positioning point during installation of a machine and can also be used for calibration of a position of the machine.

Abstract: An apparatus for testing a package-on-package semiconductor device includes a top cover, a lower base, a heat dissipation module, and a plurality of probes. The lower base is disposed under the top cover so as to form an internal accommodation space for receiving an upper chip. The heat dissipation module includes a heat sink arranged in the internal accommodation space and attached to an upper surface of the upper chip. The probes are arranged in the lower base so as to electrically connect the upper chip with a lower chip. By the heat sink arranged in the internal accommodation space formed of the top cover and the lower base, heat generated from the upper chip during operation of the upper chip can be greatly dissipated so that the performance and the service life of the upper chip can be improved.

Abstract: The present invention relates to a low-thermal resistance pressing device for a socket, which mainly comprises a housing, an inner collar, a heat conductive pressing block, a bearing collar and a locking member. The locking member on the housing is used to lock the socket. The inner collar is threadedly engaged with the housing. The bearing collar is located between the inner collar and the heat conductive pressing block. In the case of rotating the inner collar in the housing, the bearing collar drives the heat conductive pressing block to move axially so as to exert an axial force to a device to be tested. Because the heat conductive pressing block protrudes from the upper and lower surfaces of the housing, one end thereof can be in contact with a temperature control module, and the other end thereof can be in contact with the device to be tested.
