Laser soldering is a welding method that uses low melting point metal solder to heat and melt, and then infiltrate and fill the gaps at the joints of metal parts. Unlike traditional soldering with a soldering iron, laser replaces the soldering iron as the heating medium, utilizing the high energy density of laser to achieve rapid heating of local or small areas to complete the soldering process, transforming it from contact soldering to non-contact soldering.
Laser soldering is mainly divided into tin wire laser soldering, solder paste laser soldering, and tin ball laser soldering.
The principle of tin wire laser welding is that the laser first heats the product solder pad. After the solder pad reaches a certain temperature, the tin wire is sent to the solder pad and melted by the laser, so that the melted tin wire adheres to the solder pad.
The principle of solder paste laser welding is to apply solder paste on the solder pad in advance, and then heat the solder paste and product solder pad through laser radiation to reach the welding temperature, thus achieving the purpose of welding.
The principle of tin ball laser welding is to send tin ball particles to the nozzle through a ball feeding mechanism, and then irradiate the laser to melt the tin ball. The liquid tin is sprayed onto the surface of the product through nitrogen gas.
