SEHO Systems Introduces the Cost-Effective, Energy-Efficient PowerWave N2

Jun 05, 2012

PowerWave N2

PowerWave N2

 SEHO Systems GmbH, a worldwide leading manufacturer of automated soldering systems and customer-specific solutions, debuting the new PowerWave N2 with the SEHO tunnel concept for reduced nitrogen and energy consumption.

The PowerWave N2 is equipped with a closed tunnel system. The special design of the stainless steel tunnel results in low nitrogen consumption. The innovative tunnel insulation ensures very high energy efficiency, a clear advantage for production costs. Hinged heat-resistant glass covers not only make for a very attractive design but also allow for ideal accessibility to all machine areas.

The PowerWave N2 features an innovative fluxer unit that reduces flux consumption remarkably, and simultaneously makes for low maintenance requirements. The spray fluxer with HVLP technology (high-volume – low pressure) ensures a stable spray jet and a very precise spray pattern even at the outer edges of the printed circuit boards (PCBs). This allows a reproducible fluxing process with considerably reduced flux consumption. Additionally, alcohol-based as well as water-based fluxes can be processed without any problems.

The flexible preheating zone configuration with an active length of 1800 mm (70.86") enables the system to be customized to specific production needs. Depending on the requirements, the PowerWave N2 may be equipped with infrared heating zones, immediately reacting quartz emitters, or with convection heating modules. The IR preheat zones ensure even heating of the entire assembly while quartz heaters make for a quick heat transfer and compensate temperature differences because of unequal mass proportion within the assembly. Of course, each preheat zone can be adjusted individually and is separately monitored and controlled.

The heart of the PowerWave N2 – the soldering area – offers a flexible configuration that leaves nothing to be desired. Innovative, up-to-date wave formers combined with an ideal nitrogen atmosphere ensure optimum soldering results. A programmable, automatic height adjustment of the solder nozzles makes for highest flexibility. Additionally, the PowerWave N2 is ideally suited for processing lead-free solder alloys.

The PowerWave N2 is equipped with a state-of-the-art control unit concept and highlights many features that ensure comfortable and continuous control of the machine and process data. Operation is made simple with a touch display, featuring process visualization and an interactive graphic user interface. For more information, visit
