Seho StartSelective Selective Solder Machine

Ideal for those just entering automated soldering, the StartSelect is the perfect plug-and-produce selective soldering system. With a footprint of only 2.5 m2, the StartSelective provides maximum quality and reproducibility of soldering results for assemblies up to 20 “ x 20 “ and an outstanding return on investment. While all process steps are fully automated and monitored, loading and unloading of assemblies is done manually.

Optimised soldering area with non-wetted mini-wave solder nozzles, featuring a 7 ° soldering angle. The nozzles convince with stable and reproducible flow properties, resulting in high soldering quality. Even difficult geometries can be soldered easily. Moreover, non-wetted solder nozzles are maintenance-free and feature a nearly unlimited lifetime, thus avoiding follow-up costs.
