Abstract

Disclosed is an apparatus for handling electronic components and a method of adjusting the position of at least one handling device of an apparatus for handling electronic components. The apparatus comprises a rotary device; an imaging device located on the rotary device which is positionable by the rotary device; a plurality of pick heads arranged circumferentially around the rotary device, each pick head being operable to hold an electronic component; a fiducial mark located at a fixed position relative to the rotary device such that the rotary device is rotatable relative to the fiducial mark, the fixed position of the fiducial mark being indicative of an arrangement of an electronic component which is held by a respective pick head; and at least one handling device for handling the electronic components, the position of the at least one handling device being adjustable for aligning the at least one handling device with the arrangement of the electronic component held by the pick head; wherein the imaging device is operative to capture at least one image comprising the fiducial mark and the at least one handling device for deriving an offset between the at least one handling device and the arrangement of the electronic component as indicated by the fixed position of the fiducial mark.
