How to weld the connection port of Apple mobile phone data cable?

The data lines of iPhone series are all welded by sub-laser welding machine.

Details are as follows:

Welding, also known as welding and fusion, is a manufacturing process and technology to connect other thermoplastic materials such as metals or plastics by heating, high temperature or high pressure. Welding can achieve the purpose of connection in the following three ways:

1, fusion welding-heating the workpiece to be joined to partially melt it to form a molten pool, and the molten pool will be joined after cooling and solidification. If necessary, fillers can be added for assistance. Suitable for pressureless welding of various metals and alloys.

2. Pressure welding-The welding process must exert pressure on the weldment, which belongs to the processing of various metal materials and some metal materials.

3. Brazing —— Using a metal material with a melting point lower than that of the base metal as the brazing filler metal, wetting the base metal with liquid brazing filler metal, filling the joint gap, and mutually diffusing with the base metal to realize the connection of weldments. Suitable for welding of various materials and different metals or heterogeneous materials.
