Selective Soldering

For every process the most suitable technique. Whether miniwave providing maximum flexibility, multiwave soldering processes with shortest cycle times, or even conventional wave soldering processes - if needed, all three processes integrated in only one machine. Selective soldering systems from SEHO feature innovative details, maximum productivity and perfect soldering results.

SEHO LeanSelect

Innovative and Productive

Electronic productions face new manufacturing challenges more and more frequently. Besides high quality requirements at low production cost, there are also an increasing number of product variants and flexible reactions to fluctuation in demand.
The SEHO LeanSelect is particularly designed to meet these challenges, featuring highest flexibility and outstanding return of invest. While the entire process is fully automated, loading and unloading of assemblies is done manually on two separate conveyors. This allows processing of up to five carriers at the same time. The work stations are arranged in a counter-clockwise U-shape, thus consistently following the Lean Equipment Design Guidelines.

Your Advantages at a Glance:
- smallest footprint of only 2.5 m²
- ideally suited for up-to-date manufacturing islands
- high flexibility and productivity: electro-magnetic soldering unit with miniwave nozzle or multi-nozzle dip tool
- high energy efficiency: only one axis to position fluxer and soldering unit
- high production rate: up to five carriers in process at the same time
- patented, automatic ultrasonic cleaning of solder nozzles ensures a reliable process
- 100 % process control
- AOI system SEHO PowerVision integrable
- efficient programming, online or offline, and with mcServer ready for Industry 4.0

SEHO SelectLine

With a PLUS in Flexibility

With the SelectLine SEHO developed a selective soldering system featuring a revolutionary design and which convinces with highest precision and solder joint quality as well as a high degree of flexibility: no change-over is required to dynamically process a variety of assemblies with short cycle times.
The SelectLine machine concept is consistently modular, thus ensuring clear cost benefits. Fluxer module, various preheat modules and several soldering modules may be equipped individually, and a brush station as well as the SEHO PowerVision AOI system can be integrated. Depending on your requirements, the different modules can be configured to a complete manufacturing line. Even Select-Line-C that is designed for stand-alone operation in the basic configuration may be expanded with additional modules at any time to be used inline.
The SelectLine can be equipped with the SYNCHRO concept, developed by SEHO, a unique software feature that nearly doubles throughput without major investments.

Your Advantages at a Glance:
- highest flexibility: Twin-Select soldering unit
- modular expandable any time
- outstanding soldering quality: electro-magnetic soldering units
- highest throughput rates: patented SYNCHRO concept
- maximum machine availability: patented ultrasonic cleaning for solder nozzles
- 100 % process reliability: process control from A like AOI to Z like Z height
- dynamic precision: exact positioning of the work stations with highly precise axis systems
- efficient programming: offline teach program
- fast change-over and maintenance: extremely good accessibility of the soldering area
- ready for Industry 4.0: machine communication software mcServer

SEHO PowerSelective

For the Flexible Production with High Volumes

SEHO PowerSelective is featured with an outstanding modular machine construction which ensures highest flexibility. The basic system can ideally be configurated to meet different specific production requirements and it provides the opportunity to be upgraded step by step at a later date to suit subsequent production developments.
The PowerSelective may be equipped with up to two different soldering units. Thus, miniwave soldering processes, multiwave processes and even conventional wave soldering processes can be covered with only one machine.
Absolutely unique are the PowerSelective‘s outstanding features for automatic process control. Flux quantity monitoring, intelligent tool management, automatic position correction with fiducial recognition, warpage compensation and an integrated AOI system SEHO PowerVision for optical control of the solder joints are only some of the PowerSelective‘s highlights.
Highest Flexibility, absolutely reproducible results, high production volumes and maximum soldering quality sum up to one result: SEHO PowerSelective.

Your Advantages at a Glance:
- modular system which ideally fits into each production concept: inline, stand-alone and flexible lean production concepts
- the machine can be upgraded any time to minimize cycle times or to increase the production volume
- high precision portal axis system which provides maximum flexibility
- three processes – one machine: for multiwave soldering processes, miniwave soldering and conventional wave soldering processes
- multiple soldering units may be integrated into one machine.
- wetted or non-wetted solder nozzles can be used
- the rotating and tilting function of the gripper allows ideal peel-off to reduce solder bridges
- solder waves with touchless wave height control and nitrogen inertion, for best possible soldering results and highest reliability
- maximum machine availability due to quick change nozzles, and product change-over or maintenance “on-the-fly”
- user-friendly operating interface and easy-to-handle teaching function, online or offline
- 100 % automatic process control with integrated AOI system SEHO PowerVision, flux quantity monitoring and many more

SEHO MaxiSelective-HS

With a PLUS in Flexibility

The MaxiSelective-HS represents the high speed selective soldering system from SEHO. It is the perfect solution when highest soldering quality and shortest cycle times are required.
Parallel processes in the fluxing, preheating and soldering area, simultaneous contact of all solder joints with product specific multi nozzle soldering tools as well as the parallel transfer of the assemblies to the next work station make this „one product machine“ the ideal system for mass production.
Two basic machine versions of the MaxiSelective-HS that can be equipped with four or six stations working in parallel, offer the flexibility needed to meet your individual production requirements. Additional buffer stations at the inlet and outlet of the machine complete this high speed system. In order to meet complex production challenges or to respond to increasing manufacturing volumes, the MaxiSelective-HS can be expanded with additional mo-dules or it may be combined with other machine types, also at any later date.
Of course, the MaxiSelective-HS provides outstanding features for automated process control, characteristic for selective soldering systems from SEHO. Flux quantity monitoring, gradient-controlled temperature profiles, solder level control with automatic wire supply and an automated wave height control are only some of the machine’s highlights.

Your Advantages at a Glance:
- high speed selective soldering system with shortest cycle times less than 20 seconds
- this “one product system” is the ideal solution for mass production
- parallel processes in the fluxing, preheating and soldering area + parallel transfer of assemblies to the next work stations = shortest throughput times
- high precision miniwave soldering process with product specific multi nozzle tools
- nitrogen inertion of the multiwaves guarantees highest soldering quality and minimum maintenance
- 100 % process reliability: process control from A like AOI to Z like Z height
- maximum process safety: flux quantity monitoring, gradient-controlled preheat process, automatic wave height control and many more
- simple and comfortable teach process
