Laser Marking UID's

Laser Marking Application:

UID marking was done with a 20 Watt Fiber Laser Marking System using a 160 mm lens. The part was marked with multiple etched marks of 2D codes and squares. The cycle time for the 2D code was 3.28 seconds. Two different squares were marked on the part with different cycle times. The light squares had cycle times of 6.86 seconds. The dark squares had cycle times of 13.89 seconds. The 2D code was readable at our application laboratory. The best readable part was the dark 2D code on the light square.
