Non-contact Thermo Sensor Laser Solder System
Laser soldering is often applied as selective laser soldering. Selective soldering processes are used in applications where other conventional selective soldering techniques reach their limits. These limits can be for example defined by temperature-sensitive components. The transfer of heat and energy through the laser beam provides the user with many advantages, especially with view to the miniaturization of sub-assemblies or sensitive components.
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.
