Laser Engraving Accuracy|Analysis of the Conditions Needed to Make Micron-Level High-Precision Laser Marking Technology a Reality

The realization of high-precision laser marking technology at the micron scale requires the accurate setting of laser parameters, a stable equipment system, and strict environmental control.The company offers in-depth analysis of the core elements that affect processing accuracy, including laser selection, optical lens configuration, material selection, and vibration isolation, to help industrial users master the key technologies for improving marking accuracy.The company uses actual cases to demonstrate how to optimize the processing effect in different applications in order to meet the special needs of the precision manufacturing industries for medical devices and electronic components.

The first step in achieving laser marking at the micron level is to select a fiber or ultraviolet laser with an ultra-short pulse.The equipment can produce a light spot with a diameter of less than 20 μm, and when combined with a high numerical aperture F-theta field lens, can effectively control the distribution of energy.Lab tests show that when the temperature in the workshop varies by more than ± 2 ℃, the depth of the markings on metal materials can vary by 3-5 μm, so the workshop must have a temperature control system.

In the optical system configuration, the combination of an electric focus adjustment device and a CCD vision positioning system can control positioning errors within ± 1.5 microns.A certain semiconductor company was able to increase the precision of its manufacturing process from 15 μ m to 8 μ m by upgrading its galvanometer drive module.It is worth noting that the absorption rates of different materials for wavelengths of 1064nm and 532nm are quite different. For example, aluminum alloys absorb 40 % more UV than IR.

Optimizing operating parameters is also key.Through orthogonal experiments, they discovered that when the repetition frequency was raised from 20kHz to 80kHz, the sharpness of the edges of the characters on the stainless steel surface could be improved by 30 %.But it is important to note that when power density exceeds the threshold of the material, the heat affected zone is easily produced, and this requires balancing the machining quality and efficiency through the adjustment of the pulse width (it is suggested that this be controlled within the range of 10-100ns).Finally, regular calibration of the optical path and the establishment of a database of processing parameters can significantly reduce the risk of fluctuations in precision in daily production.
