PCB circuit board electronic components laser soldering application
PCB, also known as circuit board, circuit board, is the "mother of electronic products". At the same time, it is also a support for electronic components, and it is a provider of electrical connections for electronic components.
The welding of electronic components on the PCB requires a laser welding machine. The general welding machine, old iron will burn the electronic components next to it, and it is necessary to use a high-precision laser soldering machine for welding.
Laser soldering technology is a welding process that uses laser to produce instantaneous melting on the surface of the metal pad of the PCB circuit board to connect the metal.
Wetting effect

When the hot liquid solder dissolves and penetrates the metal surface of the PCB to be soldered, it is called metal dip tin or metal dip tin. The molecules of the mixture of solder and copper form a new alloy with part copper and part solder. This solvent action is called tin dip. It forms intermolecular bonds between various parts of the PCB. A metal alloy is born.化物. The formation of good intermolecular bonds is the core of the PCB soldering process, which determines the strength and quality of the PCB solder joints. Only the surface of the copper is not polluted, and there is no oxide film formed due to exposure of the PCB to the air, and the solder and the working surface need to reach an appropriate temperature.
