The VERSAFLOW Multiwave is a fully automated machine designed for the highest selective throughput with the fastest cycle times using ERSA's multiwave solder plate selective technology.
The VERSAFLOW Multiwave is a selective soldering system for maximum throughput in short cycle times, as achieved in the classical wave soldering process. The modules for fluxing, preheating and soldering are arranged below the conveyor and work simultaneously. To achieve shorter cycle times, the machine is equipped with a multiwave solder nozzle plate which allows all solder joints to be formed in the solder pot at the same time. A product-specific solder nozzle plate is produced for each PCB. There are individual solder nozzles of different sizes on the nozzle plate, corresponding to the solder joints of the PCB. In the solder pot, the nozzle plate is precisely fixed on a pump system and is permanently flooded with solder. Continuous solder flow through each individual nozzle ensures a constant transfer of energy into the solder joint. The total solder pot module is encapsulated by a hood and is flooded with nitrogen. This effectively reduces oxidation of the solder and increases solder quality. Due to the short cycle times in the solder module, the other modules of the system must orient themselves to this time. If the entire cycle time of the system must also be low, then the pre-heat process in particular must be optionally expanded. In order to effectively pre-heat the PCBs, even during short cycle times, a second optional pre-heater module is available to extend the pre-heater section. The user friendly concept of the VERSAFLOW Multiwave allows for rapid re-tooling to a different product. The solder nozzle plate exchange is simple and quickly executed. If thermally demanding PCB's will be manufactured, then top side convection heaters can be optionally installed in the free space above the pre-heater modules.
