Benefits at a glance about Auto Laser Soldering

For soldering small parts or components within the semiconductor, electronic or optoelectronic device manufacturing or assemblies industry, the diode laser is the right choice. Diode lasers are used for selective soldering because the laser power can be precisely controlled by an analog signal and the heat input into the material is very localized. That is why laser soldering is most advantageous, compared to traditional soldering methods. The process does not damage or input heat into nearby components. That is why even very small electronic components, in the range of a few tenths of a millimeter, as well as heat sensitive electronic parts can be processed. 

Fast power controllability combined with a non-contact temperature measurement to minimize thermal damage make the diode laser an ideal tool for this application. 

Conventional selective soldering techniques, such as e.g. the soldering iron, need a direct mechanical contact between the soldering tool and the solder joint, or the soldering tool has to be very close to the solder joint. Yet, in many cases, this is not possible due to a lack of space. Furthermore, within conventional selective soldering processes, the energy input is either not or is very slowly able to be influenced during the soldering process.
