What is a laser soldering machine?
This is a non-contact solder system that generates a high-energy laser beam through the oscillation of a laser diode and focuses it on the target through the lens.
◉Optional laser beam shape
The shape of the laser beam is usually circular, but by using a Slit metal light shield, a variety of beam shape changes can be made, so that the shape of the beam can match the shape of the component or pad.
◉450nm blue laser
Compared with the red laser with a wavelength of 800nm ​​to 980nm, the wavelength of the blue laser is shorter, only 450nm. For metals such as gold (Au) or copper (Cu), which strongly reflect visible light, their absorption rate for blue lasers is higher than that for red lasers, which means they can operate with lower output energy. Low output and efficient light output can reduce laser reflection and reduce product damage caused by refraction.
◉Dual beam mechanism
The emitted laser beam can be divided into two without energy loss. Just add this mechanism to the original input lens and you're done.
In recent years, lasers have been widely used in chip soldering. With the dual-beam mechanism, the electrodes on both sides of the chip can be irradiated at the same time to prevent the soldered parts from floating, tilting, or the phenomenon of standing stones (Manhattan phenomenon), which can also improve work efficiency.

The basic process of laser soldering
The process of laser soldering depends on the type of solder used (tin wire, pre-formed tin sheet, or solder paste)
In the case of using tin wire, laser light can preheat the soldering area first. In order to melt the tin and make it easy to flow, this preheating action is very important.
