SEHO Systems GmbH, a worldwide leading manufacturer of complete solutions for soldering processes and automated production lines, ensures higher productivity in electronic productions with flexible and innovative machines. SEHO will highlight new lean production concepts and automation technology in Hall 7, Stand 139 at the upcoming SMT/Hybrid/Packaging show, scheduled to take place May 5-7, 2015 at the Messe in Nuremberg, Germany.
Electronic productions face new manufacturing challenges more and more frequently. Besides high quality requirements at low production costs, there are also an increasing number of product variants and flexible reactions to fluctuation in demand.
With the new LeanSelect, SEHO is introducing an innovative selective soldering system that is particularly designed for lean production manufacturing environments, and which features high flexibility and outstanding ROI.
Loading and unloading of assemblies is done manually on two separate conveyor systems. The work stations, such as fluxing, pre-heating, soldering, and cooling, are arranged in a counter-clockwise U-shape, thus consistently following the general lean production guidelines. This allows processing of up to five printed circuit boards at the same time.
Due to its unique concept, the new LeanSelect ensures the highest productivity at a small footprint of only 2.5 m².
The process steps are completely automated and monitored. Like all selective soldering systems from SEHO, the new LeanSelect also features outstanding solutions for automatic process control. It monitors the fluxing process, including the actual applied amount, provides automatic position correction and z-height correction, controls the wave height, and traces the process completely. In doing so, LeanSelect provides the same uncompromising superior accuracy and soldering quality as higher-end systems from SEHO.
Also suitable for lean production applications but flexibly expandable is the SEHO SelectLine. The machine concept is consistently modular, thus ensuring clear cost benefits. Additional fluxer, preheat, and soldering modules can be integrated even at a later date to respond to higher complexity of board layouts or increasing throughput requirements. The technological highlight of the SelectLine is the patented Synchro concept, an intelligent software feature that doubles the production volume. Therefore, costly dual conveyor systems are not necessary.
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 miniwave solder nozzles that are patented by SEHO. Besides significant time savings in terms of maintenance, this unique feature provides an absolutely stable soldering process. Both the LeanSelect as well as the SelectLine can be equipped with this new feature.
Specific applications, such as wave soldering with masks, require selective flux applications that wet only the points to be soldered, not the entire mask. This prevents flux from running under the mask. Also, it significantly reduces flux consumption and shortens the cleaning cycles for the masks. SEHO has developed the coordinate fluxer SelectFlux for this purpose – a high-speed system that precisely applies the flux at previously programmed points. No other assembly areas are wetted.
A particularly exciting highlight at the SEHO stand (7-139) will be a special transport system, with intelligent concepts for handling of assemblies. SEHO very successfully made the step from a standard machine manufacturer to a system supplier with innovative automation technology.
