Abstract
A transfer apparatus for transferring electronic devices from a wafer to a test handler. The transfer apparatus comprises: i) a rotary device rotatable about an axis; and ii) a plurality of holders configured to hold the electronic devices for transfer from the wafer to the test handler. The plurality of holders are coupled to, and extendable from, the rotary device to pick the electronic devices from the wafer. Specifically, the plurality of holders are arranged circumferentially around, and inclined with respect to, the axis of the rotary device, so as to change an orientation of the electronic devices on the wafer to a desired orientation of the electronic devices on the test handler.
