Abstract: An apparatus for securing electronic devices on a carrier for storing electronic devices during transportation of the electronic devices on the carrier has a guiding track for guiding motion of the carrier when the carrier receives electronic devices. A magnetic track located adjacent to the guiding track attracts the electronic devices onto the carrier with a magnetic attraction force. In particular, the magnetic track has a support surface facing the carrier that has a smaller width than a width of a portion of the magnetic track that is spaced from the support surface.

Abstract: A feeding apparatus for supplying electronic devices for pick-up comprises a guide track for guiding and feeding a plurality of electronic devices and a separator operative to receive electronic devices from the guide track for the electronic devices to be picked up from the separator. A protrusion is located on either of the guide track or the separator, and a cavity is located on the other of the guide track or the separator for receiving the protrusion. The protrusion and the cavity cooperate to form a substantially continuous surface for transferring the electronic devices to the separator.

Abstract: A test handler comprises an orientation changing device having a device holder for holding electronic devices, the device holder having a vertical rotary axis. A conveying device is operative to convey electronic devices to the device holder, and a rotary motor connected to the device holder is operative to rotate the device holder about the vertical rotary axis to change an orientation of the electronic device held on it. A rotary turret of the test handler has a plurality of pick heads arranged on the rotary turret, and each pick head is configured to pick up electronic devices from the device holder.

Abstract: An apparatus for conveying electronic devices comprises a track for conveying a plurality of electronic devices in a row towards a pick-up position on the track where the electronic devices are removed by a pick-up device. A guiding portion located over the track has a first restraining mechanism formed in the guiding portion that is operative to restrain and secure a first electronic device at a first position next to the pick-up position and a second restraining mechanism formed in the guiding portion that is operative to restrain and secure a second electronic device at a second position away from the pick-up position which is immediately subsequent to the first position. The first and second electronic devices are configured to be released and conveyed towards the pick-up position when the first and second restraining mechanisms respectively are deactivated. A corresponding method is also provided.

Abstract: The invention provides a temperature monitoring system for a semiconductor test handler. A preparation stage brings a test device to a predetermined temperature for testing at a test platform at said predetermined temperature. At least one radiation sensor, such as a thermopile device, is employed in the test handler for detecting a surface temperature of the test device by measuring radiation emitted from the test device.
