Abstract:
A semiconductor device handler, comprising:at least one input track along which semiconductor devices are conveyed to at least one input shuttle; at least one stop gate; at least one singulator arm; and at least one selector arm assembly engaged with the stop gate and singulator arm for moving the stop gate and singulator arm between a hold configuration, wherein the singulator arm is distanced from the semiconductor devices and the stop gate prevents passage of a device from the input track to the input shuttle, and a release configuration, wherein the singulator arm engages at least one device to hold the device on the input track and the stop gate permits passage of a single device from the input track to the input shuttle, the selector arm assembly including: at least one fixed guide at least a portion of which is configured to fit in a gap defined by the selector arm assembly.
