SEHO North America, Inc. highlighted a full line of market leading soldering systems at the IPC APEX EXPO 2018.
The new SelectLine-20 selective soldering system features both the highest flexibility and highest production volumes with five stations working in parallel, for assemblies up to 20” x 20”. Moreover, the system is able to process long boards up to 59” in length, depending on the application. Its outstanding modular design and innovative technical details ensure clear cost benefits.
The SelectLine-20 machine concept incorporates a fluxer station featuring the highest precision with automatic position correction and fiducial recognition. To increase production volumes, several fluxer heads can be installed. The distance between the fluxer heads can be programmed through the software to ensure maximum flexibility.
The preheat area provides various stations that can be individually equipped with a convection module or quartz heaters for bottom-side heating as well as infrared heaters for top-side heating.
Highest flexibility also is achieved in the soldering area. The high performance electro-magnetic soldering units can be used for flexible miniwave soldering as well as for multiwave soldering processes to reduce cycle times significantly. Additionally, the system features SEHO’s unique Synchro mode that nearly doubles production volume without major investments.
As a particular highlight, the SelectLine-20 can be equipped with SEHO’s award-winning additional processes: An automated selective brush station to remove any residues after the soldering process and an AOI station for immediate inspection of solder joints. The advantages are obvious: Safe and reliable processes on the one hand, and reduced overall production costs on the other hand, without the need for extra floor space.
All of SEHO’s selective soldering systems feature 100 percent process control, with flux quantity control, wave height control and automatic tool measurement, process visualization, mcServer and many more value-added features. In doing so, they provide uncompromised superior accuracy and soldering quality. Additionally, SEHO’s automatic ultrasonic nozzle cleaning function guarantees reliable processes and maximum machine availability.
High mix, and simultaneously high volumes, are possible with the new features for wave soldering systems. A new preheat concept from SEHO allows minimum distances between the boards, even with very different thermal requirements. In the soldering area, an innovative solder pot concept based on electro-magnetic waves allows product changeover within seconds.
A new development from the field of reflow soldering reduces maintenance times and optimizes energy consumption. Because of its innovative details, the SEHO MaxiReflow has won several technology awards in the past. As an alternative to the proven process gas cleaning system with cyclone technology, this innovative reflow system can now also be equipped with a new pyrolysis unit. What is special about this feature: the pyrolysis unit is completely integrated in the heating chamber which completely excludes any loss of energy.
