At present, the mobile phone is becoming an essential item in people's daily life. At the same time, the functions of the mobile phones are constantly enriched, and the structure of the mobile phone is more and more complex.
A very small area is compressed by engineers for countless times in order to obtain the best design effect. In the face of such complex processing, a little more, a little less, and a little uneven will affect the operation of the whole mobile phone. Therefore, in order to ensure the perfect inlay and integration of each part, it is necessary to adopt the welding processing method with high precision.
Laser welding is to use a high-energy laser pulse to heat the material in a small area. The energy radiated by laser is diffused through the heat transfer to guide the internal diffusion of the material, and the material is melted to form a specific molten pool to achieve the purpose of welding. Laser welding has the advantages of the small heat-affected zone, small deformation, fast welding speed, flat and beautiful weld, which is suitable for welding various parts of the mobile phone. So what parts of the mobile phone need laser welding?
Application on the frame and shell of mobile phone
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 USB data line power adapter 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 phones.
Mobile phone chip usually refers to the chip applied to the mobile phone communication function. PCB is the support of electronic components and the provider of the electrical connection of electronic components. With the development of mobile phones in light and thin direction, traditional soldering is not suitable for welding the inner parts of the 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.
