In today's era of rapid technological development, the precision electronics industry has become an important force in promoting the progress of modern society. With the increasing demand of consumers for intelligent, portable and multifunctional electronic products, the competition in the industry has become increasingly fierce, which has promoted the continuous innovation of technology and the diversification of materials. The precision electronics industry not only covers consumer-level mobile devices such as smartphones and tablets, but also involves key areas such as medical equipment, high-end instruments, automotive electronic systems and industrial automation. These applications require products to have high precision, miniaturization and high stability, so process accuracy and material selection are particularly important in the design and manufacturing process.
Laser cutting technology has quickly become an indispensable tool in the manufacturing process of the precision electronics industry with its excellent cutting accuracy and extremely high processing flexibility. Compared with traditional cutting methods, laser cutting can not only process a variety of materials (such as metals, ceramics, plastics, etc.), but also has minimal thermal impact on the materials during the cutting process, and can effectively maintain the original properties of the materials. The precision of laser cutting technology makes it possible to process complex structures and fine components, meeting the urgent needs of modern precision electronic products for high-tech requirements. Therefore, laser cutting technology has played a key role in promoting the development of the precision electronics industry and has become an important means to improve product quality and production efficiency.
Laser cutting is a technology that uses a high-energy-density laser beam to cut materials. Its basic principles can be summarized in the following steps:
Laser generation: The laser generates a high-intensity beam through an excitation medium, usually using different types of lasers such as solid-state lasers, fiber lasers or carbon dioxide lasers.
Focusing and transmission: The generated laser is focused into a very small light spot through a lens system to achieve high energy density. After focusing, the laser beam is transmitted to the cutting head through an optical fiber or a mirror.
Material cutting: The laser beam irradiates the surface of the material and locally heats it to melt or vaporize. During the cutting process, auxiliary gases (such as oxygen or nitrogen) are usually sprayed in at the same time to help remove molten materials and improve cutting quality.
Cutting completion: The movement path and speed of the laser determine the shape and accuracy of the cutting. The position of the cutting head is controlled by a computer to achieve high-precision and high-complexity cutting effects.
This cutting method can process a variety of materials, including metals, plastics, wood, ceramics, etc., and has high cutting speed and accuracy.
Laser cutting has several significant advantages over traditional cutting technologies (such as mechanical cutting, stamping and water jet cutting):
● Cutting accuracy:
Laser cutting: It can achieve micron-level cutting accuracy, suitable for cutting complex shapes, with neat edges and usually no burrs.
Traditional cutting: The accuracy is low, especially when dealing with complex shapes.
● Cutting efficiency:
Laser cutting: The cutting speed is fast, which can significantly improve production efficiency, especially in large-scale production.
Traditional cutting: The speed is slow and may require subsequent processing (such as grinding and trimming).
● Heat-affected zone:
Laser cutting: The heat-affected zone is small, which can reduce material deformation and damage and maintain the mechanical properties of the material.
Traditional cutting: The heat-affected zone is large, which may cause thermal deformation and material fatigue.
● Production flexibility:
Laser cutting: The program can be quickly adjusted to adapt to different cutting needs without changing tools or molds.
Traditional cutting: It takes time to change tools and molds, and has low flexibility.
Laser cutting technology has gradually replaced traditional cutting methods due to its high precision, flexibility and efficiency, and has been widely used in the precision electronics industry.
