LED Processing with Lasers

Reliable High-Speed Marking

LEDs are expected to develop to one of the predominant light sources over the coming decades. They are already used for backlighting of flat panel televisions, mobile phones and the interior lighting of modern cars. Laser marking is an essential step in manufacturing the required LEDs.

One of our strengths is the real-time compensation of position tolerances which is indispendable for a reliable production process. Moreover our laser markers provide cost-efficient operation and high integration capability.

  • Mobile devices rely on LEDs for display and keyboard backlighting, flashlights and more.   lasers of the PowerLine series mark white ceramics used as substrate for LEDs with characters of 0.10 mm and line widths of 20 µm or EC200 data matrix codes of 1 mm edge length.
  • The market for high-power LEDs which requires full product tracebility is constantly growing. Interior lights of modern cars already make full usage of LEDs. Lasers of the PowerLine series mark leadframes during the LED production process with miniscule 2D matrix codes, made up of spots which are just 4 µm small.

  • High-power LED production usually requires traceablitiy markings with OCR or T7 data matrix codes. The marks are machine-readable, have no negative influence on subsequent manufacturing steps and still permit clear identification at the end of the process chain.
