SEHO Systems SMT Selective Wave Soldering Machines

Complete Solutions for Soldering Procesesses and Automated Production Lines

SEHO develops and manufactures soldering machines for the electronics industry that are trend setting worldwide. Our solutions stand for performance, flexibility, efficiency and for technical progress. Numerous pioneering innovations in the field of soldering originated at SEHO.  
With our modern and innovative soldering machines, and the high quality standard of our products, we are a strong and reliable partner for our customers worldwide.  
Our activities concentrate on wave soldering and selective soldering systems. From entry level GoWave up to the state of the art full tunnel nitrogen wave soldering system PowerWave N2.  
With the SelectLine SEHO developed a selective soldering system featuring a revolutionary design and which convinces with highest precision and solder joint quality as well as a high degree of flexibility: no change-over is required to dynamically process a variety of assemblies with short cycle times.
