ERSA has announced that it will present a new generation of wave soldering systems for challenging lead-free applications: the Powerflow line, at this year’s SMT trade fair in Nuremberg. The systems‘ designs are based on a modular machine concept providing maximum flexibility for the user. Whether a starter model or high-end version, the system offers numerous future-oriented and intelligent solutions for a wide range of applications. Based on a modular, subsequently expandable housing concept, the systems are available as a pure “air system” working under normal atmospheric conditions, with a nitrogen cover over the solder bath or with full nitrogen tunnelling. All wave soldering systems modules are fully capable of handling lead-free solders and VOC-free, water-based fluxes. The new spray fluxer with two-head capability allows for customized spray pattern programming both on-line and off-line. A true novelty of this feature is that it is possible to control, display and verify exactly how much flux has been drawn from the tank and deposited on the PCB. Furthermore, a second flux module can be integrated in the system.
The ERSA Powerflow is equipped with a modular, individually expandable preheating concept consisting of convection heaters and emitters. The preheating zone can be configured variably in both length and performance and adjusted subject to population densities and masses, throughput and heat requirements. The modern nitrogen tunnel concept is a highlight of the machine technology of the full nitrogen tunnel system. Minimal residual oxygen, intelligent temperature compensation, thermal stability and efficient, multilevel condensation management are only a few of its outstanding features. Each component can be assigned to the corresponding preheating temperature by means of pyrometer measurement (non-contact temperature measurement) for process monitoring and documentation of the actual component temperature. Last but not least, the modern control concept with user-friendly operation via notebook or touch screen is a decisive factor for which electronic manufacturers have shown enormous interest with the wave soldering system since its introduction onto the market.
