Smartphones have changed our lives. With the next generation of all-in-one mobile devices well on its way, it is lasers that are driving innovation for each and every component. Today, MORN LASER will introduce the application of laser welding technology in mobile phones.


Application of laser welding on mobile phone frame and shrapnel

Laser welded shrapnel

Mobile phone shrapnel, like a hub connecting 4G and 5G, connects the aluminum alloy middle frame with other structural parts of the mobile phone. Laser welding is used to weld the metal dome to the conductive position, which plays the role 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 to the mobile phone.

Using laser welding to weld the metal dome to the conductive position can resist oxidation and corrosion. Gold-plated aluminum, copper-plated steel, gold-plated steel and other shrapnel are also suitable.

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

Application of laser welding on inner metal parts of mobile phone

Laser welding of internal parts of mobile phones

There are many metal parts inside the mobile phone need to be connected together. Common mobile phone parts laser welding includes resistance capacitor laser welding, mobile phone stainless steel nut laser welding, mobile phone camera module laser welding and mobile phone RF antenna laser welding. The laser welding machine does not require tool contact during the welding of the mobile phone camera, which avoids the damage of the device surface caused by the contact of the tool and the device surface. The processing accuracy is higher. It is a new type of microelectronic packaging and interconnection technology, which can be perfectly applied to the processing of metal parts in mobile phones.

Application of laser welding on mobile phone chip and pcb board

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. With the development of mobile phones in thin and light directions, traditional soldering is no longer suitable for welding internal parts in mobile phones. Since the development of laser welding, it has continuously penetrated into every industry. With its welding efficiency and quality, laser welding has high quality and long service life. It can realize automated production and many manufacturers are using it.
