And did you know that "laser", as an advanced processing technology, plays a pivotal role in the manufacturing process of mobile phones.
Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece, vaporize the surface material or change the color of the chemical reaction, leaving a permanent mark, with high accuracy, fast speed, and clear marking Features. Mobile phones use laser marking as a permanent marking method, which can improve anti-counterfeiting capabilities and increase added value, making the product look higher-level and more brand-like.
A mobile phone has the shadow of laser marking everywhere, such as: logo marking, mobile phone keys, mobile phone shell, mobile phone battery, mobile phone accessories, etc., and even inside the mobile phone that you cannot see, there are also laser marking of parts and components. .

Laser cutting can be used for precision cutting or micro-hole processing of small workpieces such as metal or non-metal parts. It has the advantages of high cutting accuracy, high speed, and small thermal impact. Common laser cutting processes on mobile phones are: sapphire glass mobile phone screen laser cutting, camera protection lens laser cutting, mobile phone home button laser cutting, FPC flexible circuit board laser cutting, mobile phone handset laser drilling, and so on.

Laser welding uses a high energy density laser beam as a heat source to melt the surface layer of the material and solidify it into a whole. The size of the heat affected area, the appearance of the weld, and the welding efficiency are important indicators for judging the quality of the welding process. The main processing objects of Huagong Precision Laser Welding Machine are small parts such as parts, precision instruments, etc., with high welding accuracy. There are various welding supporting workbenches such as integrated and split type for selection.
LDS laser direct molding
Today, LDS laser direct molding technology has been widely used in the manufacture of smart phones. The advantage is that by using laser direct molding technology to mark the antenna trajectory on the phone case, whether it is a straight line or a curve, as long as the laser can reach it, Can create 3D effects, can save phone space to the greatest extent, and can adjust the antenna trajectory at any time. In this way, the phone can be made thinner, more refined, and more stable and shock resistant.

Personal electronic devices represented by mobile phones have positively changed and facilitated people's lives. Functionalization, intelligence, and smartness are the development direction of mobile phones. With the technological progress 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 promoting the development of other microelectronics manufacturing related industries.
