Abstract
An apparatus for laser marking IC packages carried in trays includes a transport actuator extending from an input shuttle assembly to an output shuttle assembly. The laser marking apparatus further includes a tray transport movable on the transport actuator and configured to receive a cooperatively configured tray carrier. The input shuttle assembly is adapted to load a tray carrying unmarked IC packages onto the tray carrier from a stack of trays on the input shuttle assembly. A tray bearing unmarked IC packages may travel on the tray carrier borne by the tray transport to a laser marking station positioned above the transport actuator and having a single laser marking head traversing one mark field disposed within an enclosure. A first portion of the IC packages disposed in the tray that are positioned in the mark field may be laser marked after the tray is lifted into the enclosure by a rotational lift mechanism located proximate the laser marking station.
