The smart entry into selective soldering

SEHO North America will highlight the latest GoSelective-LS selective soldering machine in booth 635 at SMTA International, scheduled to take place from 29th to 30th September 2015 at the Donald Stephens Convention Center in Rosemont, IL. SEHO continues to release new technologies to ensure higher productivity in electronic productions with flexible and innovative machines.

Electronic productions face new manufacturing challenges more and more frequently. Besides high quality requirements at low production costs, there also are an increasing number of product variants and flexible reactions to fluctuation in demand. With the GoSelective-LS, SEHO has introduced an innovative system that represents the smart entry into selective soldering. Featuring an outstanding ROI, the GoSelective-LS efficiently replaces manual soldering processes.

The GoSelective-LS is particularly designed for stand-alone production of small and medium sized volumes and it scores highly with its very compact design. To ensure an ergonomical work flow and the shortest cycle times, the GoSelective-LS is equipped with a loading and unloading station for carriers up to 500x500mm that is mounted in front of the machine. This station incorporates a manually moved cross transfer that allows users to comfortably slide the carriers from left to right and vice versa.

Therefore, it is possible to assemble boards in one carrier while a second carrier is being processed in the machine. While loading and unloading of the system is performed manually, all process steps are completely automated. The machine features a precise axis system that reliably positions the drop jet fluxer, preheat unit and soldering unit during the process. Depending on the requirements, the electro-magnetic soldering unit may be used for flexible mini-wave soldering processes, or can be equipped with a multi-nozzle tool for dip soldering with short cycle times.

Of course, SEHO’s demand for 100% process control applies to the GoSelective-LS, with fiducial recognition for automated position correction, flux monitoring, wave height control, process visualisation, mcServer and many more value-added features. In doing so, the GoSelective-LS provides the same uncompromising superior accuracy and soldering quality as high-end systems from SEHO.

Innovations from SEHO focus on one point: To continuously increase the system's productivity. This also includes reduction of maintenance times. Maximum machine availability is ensured with the automatic ultrasonic cleaning for mini-wave solder nozzles that are patented by SEHO. Besides significant time savings in terms of maintenance, this unique feature provides an absolutely stable soldering process.
