A Brief Discussion on the Application of Laser Welding Technology in the Welding of Mobile Accessories
2020-07-16
The continuous enrichment of smartphone functions has made the structure of mobile phones increasingly complex, with very small areas being compressed countless times by engineers to achieve the best design effect. In the face of such complex processing, even a slight excess or deficiency, or minor unevenness, can affect the entire phone's operation. Therefore, to ensure the perfect embedding and integration of each component, it is necessary to use highly precise welding processing methods.
The laser welding machine uses high-energy laser pulses to locally heat materials in a small area. The energy from the laser radiation diffuses into the material's interior through thermal conduction, melting the material to form a specific molten pool for welding purposes.
Laser welding has a small heat-affected zone, minimal deformation, fast welding speed, and smooth, aesthetically pleasing welds, making it suitable for welding various components of mobile phones. So, which components of the mobile phone need laser welding?
Application on the middle frame and spring contacts:
The mobile spring contact acts like a hub connecting 4G and 5G, linking the aluminum alloy middle frame with other structural components of the mobile phone.
The mobile metal middle frame connects with other structural components of the mobile phone. The metal spring contact is welded onto the conductive position using laser welding, providing anti-oxidation and anti-corrosion effects. Materials such as gold-plated aluminum, copper-plated steel, and gold-plated steel can also be welded onto mobile components using a metal parts laser welding machine.
Application on USB data cables and power adapters:
USB data cables and power adapters play an important role in our lives. Currently, many domestic manufacturers of electronic data cables use laser welding technology for their production.
Since the shielding casing of the mobile data cable and the USB head are made of stainless steel, the precision welding area is very small. The laser welding machine is a precision welding device that generates minimal heat during welding, ensuring that the internal electronic components are not damaged. It has a large welding depth, small surface width, high welding strength, and fast speed, allowing for automatic welding, ensuring the durability, reliability, and shielding effectiveness of mobile data cables.
Application between internal metal parts:
Traditional welding methods result in unattractive welds and can easily cause deformation around the product, leading to issues like de-soldering. However, the internal structure of mobile phones is intricate, and when using welding for connections, the welding point area must be very small. Ordinary welding methods are difficult to meet this requirement, so laser welding is mostly used for the welding of major components in mobile phones.
Common mobile phone component weldings include laser welding of resistors and capacitors, laser welding of stainless steel nuts, laser welding of mobile phone camera modules, and laser welding of mobile phone RF antennas. The laser welding machine does not require tool contact during the welding process of mobile phone cameras, avoiding damage to the device's surface caused by tool contact, resulting in higher processing precision. It is a new type of microelectronic packaging and interconnection technology that can be perfectly applied to the processing of various metal parts within mobile phones.
Application on chips and PCB boards:
Mobile phone chips usually refer to chips used for mobile communication functions, while PCB boards are the support for electronic components and provide electrical connections for them.
With the development of mobile phones towards being lighter and thinner, traditional tin soldering is no longer suitable for welding internal parts of mobile phones.
Using laser welding technology to weld mobile phone chips results in exquisite welds without issues like de-soldering.
Laser welding uses high energy density laser beams as a heat source to melt the surface layer of materials, which then solidify into a whole, characterized by fast speed, large depth, and minimal deformation.
