Application of laser welding in the electronics industry

Application of laser welding in the electronics industry

The hub-like mobile phones connected to 4G and 5G connect the aluminum alloy middle frame to other structural parts of the mobile phone. Laser welding is used to weld metal shrapnel to conductive positions. It is used as an antioxidant and corrosion protection. Gold-plated aluminum, copper-plated steel, gold-plated steel and other materials can also be laser welded to mobile phones as fragments.

The use of laser welding to weld the metal shrapnel to the conductive position can withstand oxidation and corrosion. Gold-plated aluminum, copper-plated steel, gold-plated steel and other metals are also suitable.

1. Laser welding the mobile phone USB data cable power adapter

USB data cables and power adapters play an important role in our lives. Nowadays, many domestic electronic data cable manufacturers use laser welding technology to weld cables.

2. The application of laser welding in the internal metal parts of mobile phones

Many metal parts need to be connected inside the mobile phone. Laser welding of ordinary mobile phone parts includes resistance-capacitance laser welding, mobile phone stainless steel nut laser welding, mobile phone camera module laser welding and mobile phone radio frequency antenna laser welding. The laser welding machine does not require tool contact when welding the mobile phone camera, thereby avoiding the surface damage of the equipment caused by the contact between the tool and the surface of the equipment. High processing accuracy. This is a new type of microelectronic packaging and interconnection technology, which is completely suitable for the processing of mobile phone metal parts.

3. Application of laser welding on mobile phone chips and printed circuit boards

Mobile phone chips usually refer to chips used for mobile phone communication functions. The PCB board is a support for electronic components and a provider of electrical connections for electronic components. As mobile phones become thinner and lighter, traditional welding is no longer suitable for welding internal parts of mobile phones. Since the development of laser welding, it has penetrated into various industries. Laser welding has high quality and long life due to its welding efficiency and quality. It can realize automated production and is used by many manufacturers.
