Plug-and-Produce Selective Soldering System.

SEHO Systems GmbH will exhibit at NEPCON China, scheduled to take place April 24-26, 2019 at the Shanghai World Expo Exhibition & Convention Center. Together with its long-standing sales and service partner in China, Toratec, the SEHO team will demonstrate the StartSelective plug-and-produce soldering system, ideal for those just entering automated soldering, in Booth 1D12.

Connect, power on and produce: The StartSelective is thought through down to the last detail, from its compact design, ease of operation that does not require special skills, and many technical highlights. 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.

All process-relevant components such as the micro drop jet fluxer, preheat system and maintenance-free electromagnetic soldering unit have successfully been in use for years in other soldering systems from SEHO. While all process steps are fully automated and monitored, loading and unloading of assemblies is done manually.

The bottom-side preheat section of the StartSelective is equipped with pulsar heaters over the full area, which can be activated individually depending on board dimensions. Pulsar heaters feature a high energy density and quick reaction time. This enables a remarkable reduction in energy consumption. An additional top-side IR preheating ensures permanent and controlled heat support during long cycles.

Another highlight is the optimized 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 outstanding 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. Additionally, they do not require any chemicals for activation – an advantage for both the health of the maintenance staff and the environment.

Just like the high-volume selective soldering systems from SEHO, the StartSelective is equipped with a complete package for automated process control. The spray jet control in the fluxing area, automatic wave height control and solder level monitoring with automated solder wire supply are only some of the monitoring functions.

The StartSelective is designed for maximum efficiency. Programming is 100 percent offline at any PC workplace so that the machine is always available for production. Loading and unloading of assemblies is done from the front side, and all setup, retooling and maintenance are easily accessible on one side of the machine. This design allows users to integrate the StartSelective in any production island with minimum footprint requirements, or to place it as stand-alone system in the corner of the production floor.
