UID marking on the part was accomplished using a 20 Watt Fiber Laser Marking System with a 160mm lens. The 160mm focal length lens has a working distance of 176mm from lens to part. A light square box was marked first; the 2D code was marked over the box. The first lighter square had a cycle time of 1.45 seconds. The cycle time for the 2D code was 14.09 seconds. The marking speed was decreased in order to get the 2D code darker. The 2D code was readable at our application laboratory.
