Laser welding process of mobile phone accessories
Laser welding machine uses high-energy laser pulse to heat the material in a small area. The energy radiated by laser diffuses through the heat transfer to guide the internal diffusion of the material, and forms a specific melting pool after melting to achieve the purpose of welding. Laser welding has the advantages of small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, which is suitable for welding various parts of mobile phone. So what parts of the mobile phone need laser welding?
Mobile phone shrapnel, like a hub connecting 4G and 5g, connects the aluminum alloy middle frame with other materials and structural parts of the mobile phone middle plate. The laser welding method is used to weld the metal shrapnel on the conductive position, which plays the role of anti-oxidation and anti-corrosion. Including gold-plated aluminum, copper-plated steel, gold-plated steel and other materials as shrapnel can also be laser welded to the mobile phone.
Application of laser welding machine in USB data line power adapter of mobile phone
USB data line and power adapter play an important role in our life. At present, many domestic manufacturers of electronic data line use laser welding technology to weld them.
The application of Laser welding machine between metal parts in mobile phone
There are so many metal parts inside the mobile phone that they need to be connected together. Common mobile phone parts are laser welding of resistance capacitor, stainless steel nut, camera module and RF antenna. Laser welding machine does not need tool contact in the process of welding camera of mobile phone, which avoids the surface damage caused by tool contact with device surface, and has higher processing accuracy. It is a new microelectronic packaging and interconnection technology, which can be perfectly applied to the processing of metal parts in mobile phone.
The application of laser welding machine in cell phone chip and PCB board
The mobile phone chip usually refers to the chip applied to the mobile phone communication function. The PCB is the support of electronic components and the provider of electrical connection of electronic components. With the development of mobile phone in the light and thin direction, the traditional soldering is not suitable for welding the inner parts of mobile phone. Since the development of laser welding, it has penetrated into every industry continuously. With the help of welding efficiency and quality, laser welding has high efficiency, good quality, long service life, and can realize automatic production. Many manufacturers are using it.
