USB data cables are used for connecting and communicating between computers and external devices. They can also be used for charging and connecting to external devices. It is commonly used to transmit data and charge it. How can such a small data line be produced?

 At present, there are two kinds of USB data cable welding: one is pure manual welding, the other is machine welding. Pure manual welding is the most primitive welding method. The workers welding with electric soldering iron in one hand and cut wire in the other hand are inefficient and waste human and material resources, while the quality cannot be guaranteed. This mode of production is being phased out.Nowadays, many domestic manufacturers of electronic data cables use laser welding technology to produce, especially the larger mobile phone industry.The shield case and USB head of the cellphone data line are made of stainless steel, and the precision welding position is small. Laser welding machine is a kind of precision welding equipment with low welding heat, which will not harm the electronic components inside when welding. The welding depth, surface width and small welding strength are high and the welding speed is fast.
