Due to increasing product changes in electronics production, it is necessary to exchange solder nozzles or readjust flux spray heads or solder pots by hand. The revolutionary VERSAFLUX flux module and VERSAFLEX solder module, which are available for VERSAFLOW 4, set entirely new standards with regard to flexibility and throughput. The VERSAFLUX module can be equipped with up to 4 spray heads installed on two completely independent axis systems, i.e. up to 2 spray heads per axis. Application of the flux to the printed circuit board is monitored by laser - resulting in a safe automated process.
