How Laser Soldering Works And Why You Should Be Interested
Laser soldering is a non-contact process that eliminates the risk of marring or damaging sensitive components. Robots are capable of producing micro-sized laser beams for otherwise difficult applications too small for iron tip soldering. Our advanced optical technology provides a reliable solution for micro and narrow pitched parts used in high-density electronic equipment.
The laser soldering process depends on the type of solder to be used (wire, pre-form or paste). In the case of solder wire, laser irradiation is performed in advance to the joint area (pre-heating). This is the most important process in order to wet and allow the solder to flow easily when supplying the solder wire to the joint area.
J-CAT MLU-808FS/ MLU-980FS
Our Desktop Laser-Soldering Robot
This robot is non-contact soldering that heats up the target with a high energy light emitted from an oscillated laser diode and is focused with a lens. Wavelength can be either 808nm or 980nm, varying between models.

Slit Beam: Laser-Shaping Technology Option
Although the laser beam shape is generally circular, this originally developed SLIT plate (metal plate with a hole) enables virtually any type of laser beam shape. Since the beam shape can be conformed to the part shape, damage to adjacent parts is greatly reduced.
Solder Paste Dispensers
Achieve ultimate small volume stability with precision nozzels. Dispensing technology provides an alternative to the classic wire feed approach. Dispensers allow for a precise amount of solder paste to be evenly distributed in micro amounts. This approach eliminates waste and increases cost effectiveness.
Lenses
The type of lens to form a laser beam is composed of two components, the “Input lens” and “Output lens”. With the combination of these lenses, over 100 diameter variations can be achieved.
