Fixed guide for singulator arm of semiconductor handler

Abstract

A semiconductor device handler has a stop gate and a singulator arm that cooperate to singulate semiconductor devices from an input track onto an input shuttle. Coordination between the gate and arm is provided by a selector arm assembly, which moves 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 includes a fixed guide, at least a portion of which is configured to fit in a gap defined by the selector arm assembly to permanently establish the gap width to be a proper alignment width.
