Laser engraving machines|The Conditions for Achieving Laser Marking of Micron-Level Characters

Achieving the precision required to laser mark tiny text in the micron range requires integrating the performance of equipment with process optimization. Core conditions include ultra-short pulse lasers, high-precision galvanometer scanners, and high-stability positioning platforms.By controlling the diameter of the laser beam's focal point (which can be less than 10 microns), adjusting the scan speed, and varying the pulse frequency, and with the help of proprietary software algorithms to compensate for thermal deformation errors, the system can meet the needs of micron-level processing in areas such as the marking of electronic components and medical instruments.The calibration of process parameters and the selection of appropriate materials are key factors in raising yields.

In order to achieve laser marking of tiny text at the micron level, first the laser must have sufficient energy stability and beam quality.The use of short wavelength UV or green lasers (such as 355nm / 532nm) can significantly reduce the size of the focused spot, and when combined with a high-precision galvanometer system (repeat positioning accuracy ≤ ± 2 μ m), precise scanning path control can be realized.In practice, orthogonal experimental methods are used to optimize parameter combinations. For example, the pulse width is compressed to the nanosecond level to reduce the heat-affected zone, and the scanning speed is controlled to between 300 and 800 mm/s to balance efficiency and clarity.

Environmental factors cannot be ignored. A temperature-controlled, humidity-controlled laboratory environment can reduce the thermal drift of equipment, and a worktable with air-cushion vibration isolation can effectively eliminate mechanical vibration interference.For different materials, such as metals, ceramics, and glass, the laser energy threshold must be measured in advance to avoid over-etching or etching too shallowly.For example, it is recommended that low-power, multiple-scan strategies be employed for stainless-steel surfaces, and that high-frequency modulation techniques be used in conjunction with brittle materials to prevent micro-cracking.

In addition, vector path optimization and real-time closed-loop feedback are also critical.Using AI algorithms to predict deformation trends and dynamically adjust focus position, the company can keep line width variation within ± 0.5 microns.In one case, a semiconductor manufacturer was able to increase its yield from 72 % to 98 % for 200 microcharacters in a 0.8 mm2 area after optimizing the duty cycle parameter.Regular cleaning of the optical lenses and adjustment of the mirror deflection angle are necessary to ensure long-term precision.
