With the continuous enrichment of the functions of smart phones, the structure of mobile phones is becoming more and more complex. Small areas are compressed by engineers for the best design effect. In the face of such complex processing, more or less, and slight unevenness will affect the operation of the whole mobile phone. Therefore, in order to ensure the perfect inlay and integration of each part, the current precision must be adopted Extremely high welding processing method for processing.
Laser welding machine uses high-energy laser pulse to heat the material in a small area. The laser radiation energy diffuses through the heat transfer and guides the material to form a specific molten pool after melting 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 various parts of mobile phone. So what parts on the mobile phone need laser welding?
Application in the middle frame, outer frame and shrapnel
Mobile phone shrapnel, like a hub connecting 4G and 5g, connects the aluminum alloy middle frame with some other material structures of the mobile phone's middle plate.
The metal middle frame of the mobile phone is connected with other material structural parts of the mobile phone middle plate. The metal shrapnel is welded on the conductive position by laser welding, which has the function 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 metal parts to mobile phone parts.
Application of USB data cable power adapter
USB data cable and power adapter play an important role in our life. At present, many domestic electronic data cable manufacturers use laser welding technology to weld them.
Because the shielding case and USB head of mobile phone data cable are made of stainless steel, the precise welding position is very small. Laser welding machine is a kind of precision welding equipment, which has small welding heat and won't damage the electronic components inside when welding. It has large welding depth, small surface width, high welding strength and high speed. It can realize automatic welding and ensure the durability, reliability and shielding efficiency of mobile phone data line.
Application in 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 phone to the light and thin direction, the traditional solder welding is not suitable for welding the internal parts of mobile phone.
Using laser welding technology to weld the mobile phone chip, the weld is exquisite, and there will be no desoldering and other adverse conditions. Laser welding uses high energy density laser beam as heat source to melt and solidify the surface of the material into a whole, which has the characteristics of fast speed, large depth and small deformation.
