Laser welding machine micro-welding technology application on mobile phone production process

The functions of smart phones are constantly enriched, and the structure of mobile phones is becoming more and more complicated. Small areas are compressed by engineers numerous times in exchange for the best design effect. In the face of such complicated processing, a little more, less, and slight irregularities will affect the operation of the entire mobile phone, so in order to ensure the perfect inlay and integration of each components, it must be processed by the highly precise welding process.
The Laser welding machine uses high-energy laser pulse to locally heat the material in a small area. The energy of the laser diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool for welding purpose. The laser welding heat affected zone is small, the deformation is little, the welding speed is fast, the weld seam is smooth and beautiful, it is suitable for welding various parts of the mobile phone. So what parts of the phone need laser welding?
1. Application of laser micro-welding on middle frame and snap dome in mobile phone

The mobile phone snap dome, like a hub that connects 4G and 5G, connects the aluminum alloy middle frame with other material and structural parts of mobile phone middle plate. The laser welding is used to weld the metal snap dome to the conductive position, which acts as anti-oxidation and anti-corrosion. Materials such as gold-plated aluminum, copper-plated steel, and gold-plated steel can also be laser-welded to mobile phones.

2. Application of laser welding machine on mobile phone usb data line power adapter
USB data lines and power adapters play an important role in our lives. At present, many domestic manufacturers of electronic data lines use laser welding to produce them.

3. Laser welding machine application on metal parts inside mobile phone
There are so many metal parts inside the mobile phone, and they need to be connected together. Common mobile phone parts welding are resistor and 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 eliminates the tool contact during the welding process of mobile phone camera, avoids the surface damage of the device, and has higher processing precision. It is a new technology of microelectronic packaging and interconnection, which can be perfectly applied to the processing of various metal parts in the mobile phone.

4. Application of laser welding machine on mobile phone chips and pcb board
The mobile phone chip usually refers to a chip applied to the communication function of the mobile phone, and the PCB board is a support body of the electronic components and is a provider for the electrical connection of the electronic component. With the development of mobile phones in the thin and light direction, the traditional soldering has not been suitable for welding internal parts in mobile phones. And the development of laser welding has penetrated into every industries with its high efficiency and good quality, the laser welding machine has long service life and is suitable for automatic production. Many manufacturers are using it.

The laser welding machine developed by Shenzhen Sunlaser is mainly for the welding of thin-walled materials and precision parts. Its heat-affected zone is small, the deformation is little, the welding speed is fast, the weld seam is smooth and beautiful, and the process can be accurately controlled. It can fix position precisely and achieve automation easily.
