Description

Technical Field

[0001] The invention relates to the technical field of laser etching processing, in particular to a laser etching processing device for electronic components of a circuit board. Background Art

[0002] Laser etching of electronic components on circuit boards is a high-precision and high-efficiency manufacturing process. The principle of laser etching is mainly based on the interaction between laser and electronic component materials. When the laser beam is irradiated on the electronic component material, the material will be locally heated and expand rapidly. Under certain conditions (such as laser power, focus, and precise control of the scanning path), the material will undergo a chemical reaction and be etched away, forming the desired graphics or text on the surface of the material.

[0003] The laser beam has extremely high precision and resolution, and can achieve micron-level or even nano-level etching of electronic component materials. This enables laser etching technology to produce circuit boards with complex structures and fine lines. The laser etching process is fast and continuous, and large-area materials can be etched in a short time. This greatly improves production efficiency and reduces manufacturing costs. With the continuous advancement and innovation of technology, the application of laser etching in the manufacture of circuit board electronic components will be more extensive and in-depth. In the future, this technology will develop in the direction of higher precision, higher efficiency, lower cost and more environmental protection. At the same time, combined with other advanced technologies (such as 3D printing, Internet of Things, etc.), laser etching processing will show its unique advantages and potential in more fields.
