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.

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.

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.

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.
