The 5G era is coming, what is the value of RFH ultraviolet lasers in the field of mobile phones

The fierce Huawei 5G war in the world in 2019 has made more people understand that the 5G era is about to come in full swing. This year, China Mobile, China Telecom, China Unicom, etc. have lined up 5G networks to grab market share.

As the main equipment of 5G, the mobile phone market has also begun to be updated. Since 2020, the global sales of 5G mobile phones have been leading the way. According to authoritative estimates, total mobile phone shipments in 2020 will exceed 750 million units. According to a report released by Goldman Sachs, the global 5G smartphone market will exceed 200 million units this year.

The degree of fever among users around the world for 5G mobile phones is enough to find out the degree of preference for high-quality mobile phones. The rapid development of mobile phones is inseparable from the participation of laser technology.

Laser processing has the characteristics of good cutting quality, high cutting efficiency, and fast cutting speed. Compared with traditional contact cutting processing, it has outstanding advantages. And such advantages have shown the trend of alternative applications in manufacturing fields that require high precision and high efficiency, such as the communications semiconductor industry, consumer electronics manufacturing, and the automotive industry.

Especially in the mobile phone manufacturing process, the brand LOGO marking of the mobile phone, the cutting of 3D glass and LED panel, the metal middle frame and the laser drilling of the inner parts of the mobile phone are all inseparable from laser processing equipment. In addition to the increasing application of laser technology in mobile phones, all aspects of the mobile phone manufacturing process are increasingly dependent on laser equipment, and there are basically no processes that lasers cannot complete. Therefore, laser has become the secret of mobile phone manufacturing.

laser cutting

The PCB board is extremely delicate, and the cutting or marking on it needs to be able to achieve the accuracy requirements below 0.1mm, and can not cause the PCB board to deform, so traditional cutting tools such as milling cutters, cutters, gongs and other processes and traditional circuit boards Marking tool printing inkjet can no longer meet the rapid development and replacement of its technology.

Laser cutting technology is very common in the current mobile phone manufacturing process. The internal structure of the mobile phone is generally cut by ultraviolet laser technology, mainly cutting FPC soft boards, PCB boards, soft and hard bonding boards and cover film laser cutting. Windows and so on. Laser drilling can also be regarded as a part of laser internal structure cutting.

Laser processing, especially ultraviolet laser processing, has become an important application tool that supports the in-depth innovation of PCB boards. It has very little thermal effect on the material, is not easy to deform, and has a low degree of carbonization. It can be remotely controlled by a computer with high precision. In addition, the UV laser can also perform PCB hole rotation and engraving. Laser drilling has the advantages of high efficiency, low cost, small deformation, and wide application range in mobile phone applications.

Laser Marking

A beautiful and elegant mobile phone is inseparable from its cool and attractive appearance. Traditional crafts such as silk screen contain a lot of harmful heavy metals and inks, which makes it not only taste heavy, not delicate, difficult to follow the color, but also No longer meet the low-carbon concept of green and environmental protection.

Laser processing can not only achieve high-precision, high-difficulty, and permanent marking effects, but also enhance the anti-counterfeiting performance of mobile phones, and enjoy the class and brand sense.

Laser marking technology is currently very mature and cost-effective, fast processing speed, good marking quality, green and environmentally friendly and efficient, so it is widely used. In the field of mobile phones, it is mainly applied to the surface logo mark, text mark, and internal electronic elements. The logo, text mark, etc. of devices and circuit boards. The logo, buttons, casing, battery and mobile phone accessories on the mobile phone are currently marked with laser equipment.

Laser etching

High-precision peeling is inseparable from laser. Laser etching is mainly laser etching of conductive glass on mobile phone screens. Its function is to isolate a whole piece of conductive material through a laser etching process. This process requires high accuracy and cannot be recognized by the human eye. It needs a magnifying glass to see. Its etching accuracy is normal. A fraction of the diameter of the hair.

In addition, the UV laser works quickly when producing circuits, and can etch the surface pattern on the circuit board in a few minutes. This makes UV lasers the fastest way to produce PCB samples.

Technical characteristics of UV lasers

As a cold processing method, the UV laser usually has an output wavelength below 0.4μm. It can be focused to a point on the order of submicron and is more easily absorbed by the material.

Therefore, it can act on a variety of mobile phone materials, whether it is metal, plastic, or dielectric material, liquid crystal material, etc., it can be processed without damaging the material.

Mobile phone shells, chips, PCB boards, screens, films, etc. can all be processed without contact with lasers. It has high efficiency, low cost, high precision, no damage to the machine, strong anti-counterfeiting, and no pollution. It is processed by mobile phone accessories. Excellent "black technology".

In-depth exploration *S9 series

"A more economical and wonderful mobile phone laser technology experience" RFH, carefully researched and developed, continuously innovated, and launched a new series of ultraviolet lasers S9. This series can realize the precision processing of mobile phones and related accessories, and is safer, more convenient, and more space-saving. Cost and efficiency are higher!

The RFH solid-state UV laser has a higher accuracy of ±0.01mm, and has an internal cavity self-purification system. While ensuring stable operation, it can also extend the life of the laser, greatly reduce maintenance costs, and have a longer life.

The same cavity can produce lasers of different powers, and the stability of different power ranges is greatly improved, and one is better than many.

In addition to the application of lasers in the manufacturing process of mobile phones, more and more applications of lasers are also used in the functional reality of mobile phones. In fact, without the application of laser equipment, many current mobile phone processes cannot be realized.

With the advent of the 5G era, laser technology will play a more profound value application in the field of mobile phones!
