Laser welding machine process application in 3c electronics mobile phone metal dome - Shenzhen Sun Laser

In the 21st century, mobile phone has become an indispensable item for people. The huge market demand has promoted the phenomenon of fierce competition in the field of mobile phone manufacturing. With the advent of the 5G era, the requirements are higher on the signal transmission capability of mobile phone cases. High aluminum glass, zirconia ceramics and composite materials stand out. These three materials have little effect on RF signals, however, both glass and ceramics are relatively fragile with low processing yield. The texture and surface hardness of the composite materials need to be improved.

In response to these problems, the mobile phone metal dome connection technology appears. The mobile phone metal dome, like a hub that connects 4G and 5G, it connects the aluminum alloy middle frame with other material structural parts of the mobile phone middle plate.

Using laser micro welding to weld the metal dome to the conductive position, it plays a role in oxidation resistance and corrosion resistance. Metal dome materials such as gold-plated aluminum, copper-plated steel, and gold-plated steel can also be laser-welded to mobile phones.

The mobile phone metal dome Laser welding machine works by using high-intensity laser beam to radiate to the metal surface. Through the interaction of the laser and the metal, the metal absorbs the laser and converts it into heat to melt the metal, then cools down and crystallizes after melting. Furthermore, the purpose of the butt joint welding, the stitch welding and the corner welding is achieved.

The mobile phone metal dome laser welding machine produced by Shenzhen Sun Laser Technology Co., Ltd., also known as nanosecond pulse laser welding machine, is mainly for welding thin walled materials, precision parts, and anisotropic metal materials. It has small heat affected zone, can achieve spot welding and stitch welding. And it has purifying effect, low harmful substance in the weld seam, and the resistance to porosity and crack.
