Laser welding machine

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 interior of 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 a small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welds, and is suitable for welding various parts of mobile phones. So what parts of the mobile phone need to be laser welded?

01

Application on the outer frame and shrapnel of mobile phone

The 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 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.

Application on 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.

Application between metal parts inside mobile phone

There are many metal parts inside the mobile phone, so they need to be connected together. Common mobile phone parts are welded with 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 need tool contact in the process of welding the camera of the mobile phone, which avoids the surface damage of the device caused by the contact between the tool and the surface of the device, and has higher processing accuracy. It is a new type of microelectronic packaging and interconnection technology, which can be perfectly applied in mobile phones. The machining process of each metal part.

Application in mobile phone chips and pcb boards

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 welding efficiency and quality, laser welding has high quality, long service life, and automatic production. Many manufacturers are using it.
