Laser welding process of mobile phone parts

With the continuous enrichment of smart phone functions, the structure of mobile phone is becoming more and more complex. A small area has been compressed by engineers for countless times in exchange for the best design effect. In the face of such complex processing, a little more, a little less, and slight unevenness will affect the operation of the whole mobile phone, so in order to ensure the perfect inlay and integration of each part, It must be processed by the welding processing method with high precision.

Laser welding machine is the use of high-energy laser pulse to heat the material in a small area. The energy of laser radiation is guided to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool to achieve the purpose of welding. Laser welding has the advantages of small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld, which is suitable for welding all kinds of mobile phone parts. What parts of mobile phone need laser welding?

01. Application of laser welding machine in mobile phone frame and shrapnel

Mobile phone shrapnel, like a hub connecting 4G and 5g, connects the aluminum alloy middle frame with other material structural parts of mobile phone middle plate. The metal shrapnel is welded on the conductive position by laser welding, 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.

02. 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.

03. Application of laser welding machine in the internal metal parts of mobile phone

There are so many metal parts in the mobile phone that they need to be connected together. The common welding methods of mobile phone parts include resistance capacitor laser welding, stainless steel nut laser welding, mobile phone camera module laser welding and mobile phone RF antenna laser welding. Laser welding machine does not need tool contact in the process of welding mobile phone camera, which avoids the surface damage caused by tool contact with the 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.

04. Application of laser welding machine in mobile phone chip and PCB board

Mobile phone chip usually refers to the chip used in mobile phone communication function. PCB board is the support of electronic components and the provider of electrical connection of electronic components. With the development of mobile phones to thin direction, the traditional solder welding is not suitable for welding the internal parts of mobile phones. Since the development of laser welding, it has penetrated into every industry. With welding efficiency and quality, laser welding has high efficiency, good quality, long service life, and can realize automatic production. Many manufacturers are using it.
