SEHO MaxiSelective-HS: High Speed Selective Soldering

The MaxiSelective-HS represents the high speed selective soldering system from SEHO. It is the perfect solution when highest soldering quality and shortest cycle times are required.

Parallel processes in the fluxing, preheating and soldering area, simultaneous contact of all solder joints with product specific multi nozzle soldering tools as well as the parallel transfer of the assemblies to the next work station make this „one product machine“ the ideal system for mass production.

Two basic machine versions of the MaxiSelective-HS that can be equipped with four or six stations working in parallel, offer the flexibility needed to meet your individual production requirements. Additional buffer stations at the inlet and outlet of the machine complete this high speed system. In order to meet complex production challenges or to respond to increasing manufacturing volumes, the MaxiSelective-HS can be expanded with additional mo-dules or it may be combined with other machine types, also at any later date.
