A method of pick-and-place alignment comprises (a) determining a pick location of a device from a tray of devices; (b) determining place location of the device using an up-looking camera; and (c) determining offset error for the device by comparing the pick location and the place location. The method may further comprise repeating steps (a)-(c) for additional devices on the tray of devices; and generating an offset map for alignment of devices on the tray. The method further uses the offset map to make pick and place corrections during runtime.

Up-look camera based vision apparatus to auto align pick-and-place positions for device handlers

A semiconductor handler subassembly is provided. The semiconductor handler subassembly includes an adjustment apparatus with a floating lock that is configured to adjust and lock in place to a desired position, and a tip attached to the floating lock and configured to engage a part.

Pick and place handler with a floating lock device

An apparatus for handling electronic devices in a system that assigns a category corresponding to one of a plurality of predetermined categories to the electronic devices and sorts the electronic devices according to the categories is provided. A plurality of platforms, each for supporting one tray that carries one or more electronic devices, and each platform corresponding to one of the categories, are vertically stacked in a predetermined order according to the plurality of categories. A group of the stacked platforms are separated from a platform located at a first position corresponding to a particular category corresponding to the category of an electronic device to expose a tray and enable the electronic device to be placed on the tray. A method of handling electronic devices is also provided.
