Application of laser welding head in the processing of mobile phone parts
With the continuous enrichment of functions of smart phones, the structure of mobile phones has become more and more complex. Engineers compressed a small area countless times to get the best design results. In the face of such complex processing, a slight unevenness will affect the operation of the entire phone. Therefore, in order to ensure the perfect embedding and integration of each component, it must be processed using a welding method with extremely high precision.
The laser welding head uses a high-energy laser head laser pulse to locally heat a small area of material. The laser radiation energy from the laser head diffuses into the material through thermal conduction, melts the material and forms a specific molten pool for the purpose of welding. The laser welding head has small welding heat affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, and is suitable for welding various components of mobile phones. Which parts of the mobile phone need laser welding?
1. Application of laser welding head on mobile phone frame and shrapnel
The mobile phone shrapnel, such as the hub connecting 4G and 5G, connects the aluminum alloy middle frame with other material structural components of the mobile phone middle plate. The metal shrapnel is welded at the conductive position by the laser welding head welding method, which has the functions of anti-oxidation and corrosion resistance. Materials including gold-plated aluminum, copper-plated steel, gold-plated steel, shrapnel, etc. can also be welded to the phone by laser welding heads.
2. Application of laser welding head in mobile phone usb data line power adapter
USB cables and power adapters play an important role in our lives. At present, many domestic electronic data cable manufacturers use laser welding head welding technology to weld them.
3. Application of laser welding joints of mobile phone metal parts
There are many metal parts in a mobile phone that need to be joined together. Common mobile phone accessories include welding capacitors and capacitor laser welding heads, mobile phone stainless steel nut laser welding heads, mobile phone camera module laser welding heads and mobile phone RF antenna laser welding heads. The laser welding head does not require tool contact in the process of welding the camera of the mobile phone, thereby avoiding damage to the surface of the equipment caused by the contact between the tool and the surface of the equipment, and has high processing accuracy. Laser welding head is a new type of microelectronic packaging and interconnection technology, which can be perfectly applied to the processing of various metal parts in mobile phones.
4. Application of laser welding head on mobile phone chip and PCB
Mobile phone chips generally refer to chips used for mobile phone communication functions. Pcb is a support and electrical connection provider for electronic components. With the development of mobile phones in the thin and light direction, traditional welding spot welding is no longer suitable for welding internal parts of mobile phones. Since its development, laser welding heads have penetrated into various industries. The laser welding head has the advantages of welding efficiency and quality, high welding efficiency, good quality, long service life, and can realize automatic production. Many manufacturers are using laser welding tips.
