New Soldering Module for the POWERFLOW ULTRA

At the heart of the POWERFLOW ULTRA is the new soldering module with unique process control and flexibility. Its innovative drive achieves travel speeds of up to 5 mm/s. The distance between the soldering nozzle and the PCB is defined via the ERSASOFT 5 operating software. This allows assemblies to be soldered at a precise distance. The nozzle distance and solder wave height can also be adjusted as required within an assembly.

For this purpose, the PCB is divided into sectors under program control, which are stored with parameters. This means that each sector can be soldered with individual configurations, ensuring highly flexible processes. In addition, the contact time of the solder wave with the assembly can be stored in the soldering program. This offers maximum process control when moving the assembly into and out of the solder wave. In combination with the nozzle spacing, an optimum solder flow is achieved, resulting in perfect solder joints - especially for assemblies that are equipped with a high proportion of digital components in addition to power electronics.
