With the continuous enrichment of smartphone functions, the structure of mobile phones has become more and more complex. In order to achieve the design effect, the engineer compresses the small area. Faced with such complex processing, more or less, a little unevenness will affect the operation of the entire mobile phone. Therefore, in order to ensure the inlay and integration of various components, the current high-precision welding processing method must be used for processing.
The laser welding machine uses high-energy laser pulses to heat the material in a small area. The laser radiation energy diffuses through heat transfer and guides the material to form a specific molten pool after melting, so as to achieve the purpose of welding. Laser welding has the advantages of small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, etc. It is suitable for welding various parts of mobile phones. So which parts on the mobile phone need laser welding?
Application of laser welding machine on mobile phone frame and shrapnel
The mobile phone shrapnel is like a hub connecting 4G and 5g, connecting the aluminum alloy middle frame and other material structures of the middle plate of the mobile phone. The metal shrapnel is welded to the conductive part by medical machining, which has the effect of anti-oxidation and anti-corrosion. Shrapnel including gold-plated aluminum, copper-plated steel, gold-plated steel and other materials can also be laser welded to the mobile phone.
Application of laser welding machine in mobile phone USB data line power adapter
USB data cables and power adapters play an important role in our lives. At present, many domestic electronic data cable manufacturers use laser welding technology for welding.
Application of laser welding machine in mobile phone metal parts
There are many metal parts inside the phone, and they need to be connected together. Common welding of mobile phone parts includes resistance-capacitance laser welding, mobile phone stainless steel nut laser welding, mobile phone camera module laser welding, mobile phone radio frequency antenna laser welding. The high speed machining machine does not require tool contact in the process of welding the mobile phone camera, which avoids the equipment surface damage caused by the contact between the tool and the equipment surface. It is a new microelectronic packaging and interconnection technology that can be applied to the processing technology of mobile phone metal parts.
Application of laser welding machine in mobile phone chip and PCB board
The mobile phone chip usually refers to the chip used for the communication function of the mobile phone. The PCB board is a matching supplier of electronic components and a supplier of electrical connections for electronic components. With the development of mobile phones in the direction of light and thin, traditional soldering is no longer suitable for welding internal parts of mobile phones. Since the development of aluminum parts technology, it has continuously penetrated into all walks of life. With the improvement of welding efficiency and quality, laser welding has the advantages of high efficiency, good quality and long service life, and can realize automatic production. Many manufacturers are using it.
