Application of laser welding in mobile phone industry

2020/10/23

With the continuous enrichment of smartphone functions, the structure of mobile phones is becoming more and more complex. A small area has been compressed countless times by engineers in exchange for the best design effect. In the face of such complex processing, there is more, less, and subtle unevenness. Will affect the operation of the entire mobile phone, so in order to ensure the perfect inlay and integration of each component, it is necessary to use the current extremely high-precision welding processing method for processing.

The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding. Laser welding has small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, suitable for welding various parts of mobile phones. So what parts on the mobile phone need to be laser welded?

1. The application of laser welding machine on the outer frame and shrapnel of mobile phone
Mobile phone shrapnel, like a hub connecting 4G and 5G, connects the aluminum alloy middle frame with some other material structural parts of the mobile phone middle plate. The metal shrapnel is welded to the conductive position by laser welding, which has the effect of anti-oxidation and anti-corrosion. Materials including gold-plated aluminum, copper-plated steel, and gold-plated steel as shrapnel can also be laser welded to the mobile phone.
2. Application of laser welding machine in mobile phone usb data line power adapter
USB data cables and power adapters play an important role in our lives. At present, many domestic manufacturers of electronic data cables use laser welding technology to produce and weld them.
3. The application of laser welding machine between the metal parts inside the mobile phone
There are many metal parts inside the mobile phone, so they need to be connected together. Common mobile phone parts welding include resistance capacitor laser welding, mobile phone stainless steel nut laser welding, mobile phone camera module laser welding, and mobile phone RF antenna laser welding. The laser welding machine does not require tool contact in the process of welding the camera of the mobile phone, avoiding the surface damage of the device caused by the contact between the tool and the device surface, and the processing accuracy is higher. It is a new type of microelectronic packaging and interconnection technology, which can be perfectly applied in the mobile phone. The machining process of various metal parts.
4. Application of laser welding machine in mobile phone chip and pcb board

The mobile phone chip usually refers to the chip used in the communication function of the mobile phone. The Pcb board is the support body of the electronic components and the provider of the electrical connection of the electronic components. With the development of thin and light mobile phones, traditional soldering is no longer suitable for welding internal parts in mobile phones. Since its development, laser welding has continuously penetrated into every industry. With its welding efficiency and quality, laser welding has high efficiency and long service life, and can realize automated production. Many manufacturers are using it.
