High-End-Selective Soldering System Ersa VERSAFLOW 4/55
High-End-Selective Soldering System Ersa VERSAFLOW 4/55
Industry 4.0 as a powerful instrument for increasing processes and technological sustainability on the customer side
Ersa flux module VERSAFLUX - individually adjustable flux heads in x/y/z direction
Ersa VERSAFLEX solder module - x/y/z-variable solder pots
Ersa CAD Assistant 4 - automatic division of the single jobs to the individual modules, autorouting function and real-time simulation assure optimized, zero-error sequences at highest soldering quality
Ersa VERSAEYE module - perfectly documented solder joint quality especially for the inspection of THT-solder joints
Solder joint without pin - recognized with VERSAEYE module
Ersa VERSASCAN Board Examination - VERSASCAN module recognizes multi-codes - by Bad Board Detection reject parts are detected and not further processed
Recognition of components by VERSASCAN module
