Application of laser technology in mobile phones

December 30, 2021

Mobile phones have long become an indispensable personal item in people's daily life. A smart phone can realize all functions such as instant messaging, taking pictures, using APP, playing games and even paying for purchases. And did you know? As an advanced processing technology, "laser" has played a pivotal role in the manufacturing process of mobile phones!

 

Laser Marking

Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize the surface material or produce a chemical reaction of color change, thereby leaving a permanent mark. It has high precision, fast speed and clear marking. Features. The mobile phone uses laser marking as a permanent marking method, which can improve the anti-counterfeiting ability, but also increase the added value, so that the product looks higher and more brand-like.

We can find the shadow of laser marking everywhere on mobile phones, such as: Logo marking, mobile phone buttons, mobile phone shells, mobile phone batteries, mobile phone accessories marking, etc. Even in the mobile phone that you can’t see, there are parts laser marking. Mark.

Laser cutting

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 low thermal impact. Common laser cutting processes on mobile phones include: 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 receiver net laser drilling and so on.

 

Laser welding

Laser welding uses a high-energy density laser beam as a heat source to melt and solidify the surface of the material into a whole. The size of the heat-affected area, the beauty of the weld, and the welding efficiency are important indicators for judging the quality of the welding process. The main processing objects of HG Laser Precision Laser Welding Machine are small workpieces such as parts and precision instruments. The welding accuracy is high. There are a variety of welding supporting workbenches such as integrated and split types for selection.

 

LDS laser direct forming

Nowadays, LDS laser direct structuring technology has been widely used in the manufacture of smart phones. Its advantage lies in the use of laser direct structuring technology to mark the antenna track on the phone case, whether it is a straight line or a curve, as long as the laser can reach the place. It can create a 3D effect, save the phone space to the greatest extent, and can adjust the antenna trajectory at any time. In this way, mobile phones can be made lighter, thinner, more refined, and more stable and shock resistant.

Personal electronic devices represented by mobile phones are positively changing and facilitating people's lives. Functionality, intelligence, and dexterity are the development directions of mobile phones. With the technological advancement of the microelectronics industry and people’s pursuit of individualization of mobile phones, fine laser processing technology will play an increasingly important role in mobile phone manufacturing. At the same time, laser is also promoting the development of other microelectronic manufacturing related industries.
