Application of Laser Technology in Mobile Phone

Laser marking is a marking method that uses a high-energy-density laser to locally illuminate a workpiece to vaporize the surface material or cause a color change, thereby leaving a permanent mark with high precision, high speed, and clear mark. Features. The mobile phone uses laser marking, which is a permanent marking method, which can improve the anti-counterfeiting ability and increase the added value, so that the product looks higher grade and more brand-like.

On the mobile phone, we can find the shadow of laser marking everywhere, such as: logo marking, mobile phone buttons, mobile phone case, mobile phone battery, mobile phone jewelry marking, etc., even inside the phone you can not see, there are parts laser Standard.

Laser cutting can be used for precision cutting or micro-hole machining of small workpieces such as metal or non-metal parts. It has the advantages of high cutting precision, fast speed and small thermal influence. The common laser cutting processes on mobile phones include: laser cutting of sapphire glass mobile phone screen, laser cutting of camera protection lens, laser cutting of mobile phone Home button, laser cutting of FPC flexible circuit board, laser drilling of mobile phone handset network, and so on.

Laser welding uses high energy density laser beam as heat source to melt and solidify the material surface into a whole. The size of heat affected zone, weld beautifulness and welding efficiency are important indexes for judging the quality of welding process. Huagong Laser Precision Laser Welding Machine mainly processes parts, precision instruments and other small workpieces. It has high welding accuracy, and has a variety of welding supporting Workbenches for selection, such as one-piece, split-type and so on.

Nowadays, LDS laser direct forming technology has been widely used in the manufacture of smart phones. Its advantage is that the antenna trajectory on the mobile phone shell can be marked by using laser direct forming technology. Whether it is straight line or curve, as long as the laser can reach, the 3D effect can be created, the space of mobile phone can be saved to the greatest extent, and the antenna trajectory can be adjusted at any time. In this way, mobile phones can be made thinner, more sophisticated, more stable and seismic.

With the continuous improvement of people's living standards, people's demand for automobiles is also growing. At the same time, more and more attention is paid to the performance and after-sales maintenance of automobiles. Faced with opportunities and challenges, many automobile manufacturers have to seek breakthroughs in manufacturing.

Laser marking machine technology is one of the largest applications of laser processing. Laser marking, as a new and high-tech marking method, is a marking method that uses high energy density laser to irradiate the workpiece locally, to vaporize or change the color of the surface material, thus leaving a permanent marking. Laser marking can produce all kinds of characters, symbols and patterns. The size of characters can range from millimeter to micrometer, which has special significance for anti-counterfeiting of products. Compared with the traditional marking methods such as mould, electric corrosion marking, non-adhesive, screen printing and startup marking, laser marking has the characteristics of fast processing speed, high precision and never wearing out. At the same time, laser marking belongs to a non-contact processing process, and there is no mechanical effect in the process of processing, and it will not damage the material on the surface of the processed items. So the automobile manufacturers now. In order to ensure the labeling effect of parts, laser is widely used to label parts information. Laser equipment adopts computer software control system, which has strong compilability and stable performance. It can not only edit the pattern and text of automobile parts, but also meet the needs of mass production and personalized customization. It provides more space for automobile design and manufacturing.

Nowadays, people pay more attention to the performance of the car, and the safety concerns are also increasing. The auto parts belong to many varieties and large-scale production. At present, the quality control mainly adopts the sampling method, which is an after-the-fact inspection and cannot prevent it in the production process. The role of control. Now, through information traceability, we can change the quality control from after-the-fact to pre-existing prevention. Laser marking plays an important role in this process. With laser-marked parts information, we can discover and timely through online monitoring. Eliminate abnormal parts, prevent defective products in production and check the quality of products; and also for those defective products that cannot be detected in production, we can trace the information through the information marked on the parts, thus Quickly identify the cause and batch of defects and make a quick response in a timely manner. This not only effectively improves the quality of the auto parts, but also ensures the safety of the car, allowing us to provide one more guarantee for each car passenger, avoiding some accidents caused by small faults.

The personal electronic devices represented by mobile phones have changed and facilitated people's lives positively. Functionalization, intelligence and smart beauty are the development direction of mobile phones. With the technological advancement of the microelectronics industry and the pursuit of personalization of mobile phones, fine laser processing technology will play an increasingly important role in mobile phone manufacturing. At the same time, lasers are also driving the development of other microelectronics manufacturing related industries.
