Customers often inquire whether they need to add solder (solder paste, wire, or spheres) when using laser soldering machines. Unlike traditional soldering with a soldering iron, laser soldering is a non-contact method. The solder material includes solder paste, solder spheres, solder wire, and solder rings. Different solder materials can be chosen based on various processes and workpiece requirements. Below, we will specifically discuss the principle of the laser soldering machine.

A laser soldering machine is a device that utilizes a laser beam for the welding process. Its principle involves focusing the laser beam onto a very small area, then heating and melting the material to achieve welding by concentrating it onto a tiny soldering point.

Specifically, the laser soldering machine utilizes high-energy-density laser beams to act on the soldering point, achieving the melting and re-solidification of metal or alloy materials by absorbing the instant high temperature. During this process, the distance between the laser beam and the workpiece, as well as the control of the laser beam's energy and time, are crucial, as they directly affect the welding quality.

Therefore, when using a laser soldering machine, it is necessary to select appropriate laser parameters based on the material to be焊接 and the shape, size, and quantity of the parts to achieve optimal welding results.
