How can a laser operator determine the settings to use for marking electronic devices?

If possible, always use broken or extra parts when testing. If a test part is not available, make sure the electronic device is secure to ensure there is no movement during processing. Begin with a normal engraving speed and a very low laser power. Run the job with increased laser power until you receive the desired marking quality. Once you’ve found the correct parameters for this device, you can save them for future use.
