With a wide range of processing, laser processing technology can adapt to the processing needs of different industries, whether in metalsProcessing, plastic processing or electronic processing and other fields can play an important role.
Laser drilling can also be used to process watch diamonds. It can drill 20 to 30 holes per second, several hundred times higher than the machining efficiency, and high quality. At the same time, laser drilling and the laser cutting we will talk about below, the processing process is non-contact, that is, unlike mechanical processing, the steel bit is gradually drilled through the metal material. Therefore, the laser operation can play a role in automated continuous processing, or in special environments with ultra-clean and vacuum.
Various uses of lasers: Medical field Lasers are widely used in the medical field. Laser surgery, for example, uses high-energy laser beams to cut or ablate tissue, with the advantage of high accuracy and less bleeding. In addition, laser treatment is often used in ophthalmology, dermatology and other fields, such as vision correction surgery, removal of skin lesions, and promotion of wound healing. The application of laser in industrial manufacturing is also very important.
Laser communication. Optical fiber image transmission capacity, long distance laser medicine. It can play a variety of roles such as drill, scalpel, welding gun, or laser surgery treatment, low laserNon-surgical treatment of biostimulatory effects and photodynamic treatment with laser. laser distance measuring (laser distance measuring) is a laser as a light source for distance measurement.
In the industrial field, laser technology is mainly used for measurement, molding, carving, marking and welding. In terms of measurement, LiDAR is widely used in environmental monitoring, automatic driving and other fields because of its high precision and high resolution. In terms of molding, laser cutting, laser welding and other technologies play an important role in the automotive, aviation and other manufacturing industries.
Laser in film and televisionThe application of the production is more extensive, through the laser technology can achieve high-quality image synthesis, special effects production, etc., for the audience to bring a shocking audio-visual experience. In the field of scientific research, laser technology plays an important role in many fields such as material science, optical research, and biomedicine. Laser is used for material surface modification, nanomaterials preparation, spectral analysis, etc., which has promoted the in-depth development of scientific research.
Laser can be used for industrial processing, such as some characteristics of the material (including metal and non-metal) cutting, welding, surface treatment, drilling and other treatment; Lasers can also be used in object recognition applications;It can also be used in medicine, such as laser therapy, for surgical operation, to reduce pain and reduce infection.
Laser systems can be divided into continuous wave lasers and pulsed lasers. By irradiating the diseased part of the laser beam, the pain symptoms can be eliminated or relieved, the local blood supply can be promoted, the blood circulation can be improved, the local damaged tissue can be repaired, and the local aseptic inflammation can be eliminated. Semiconductor laser mainly uses light waves with a wavelength of 650nm, which can penetrate deep tissues of the human body to play a role, and the penetration depth can reach 7 cm, so that the pain symptoms of patients can be reduced.
1, open the phone, and then re-weld the WiFi module solder, it is best to melt the original solder joint and re-weld. The reason for the welding is only because of overheating (cutting card, system overload, poor heat dissipation, environmental factors, poor signal repeatedly connected to the network, charging while using, etc.) caused by wifi module solder solder solder solder solder solder, of course, there are also a small number of chips burned and damaged, by viewing the wireless LAN address can be distinguished.
2. iphone4s wifi virtual welding is a common problem, you can try the following methods: restore the Settings five times in a row, set - General - cellular mobile network - cellular mobile data network - Restore Settings *5 - restart.
3, so in the spirit of the lowest cost, the most convenient principle, the business must be re-welded. (If it is really virtual welding, I personally feel that as a consumer, you may not be able to find the problem of virtual welding of wifi modules, too professional. Most of us can only understand that the connection to wifi sometimes no, or can be connected.
