At Productronica 2013 Seho will introduce the new product family SelectLine, a fully modular selective soldering system. Its revolutionary design convinces with high precision and a high degree of flexibility – no change-over is required to dynamically process a variety of assemblies with short cycle times. In the fluxing area, the new creative axis fluxer offers extra versatility. Multiple axes are used for parallel, even asymmetrical fluxing to help reduce cycle times. Its high-precision micro-drop nozzles can be programmed completely independently. And of course, different fluxes can be made available permanently to cover various process requirements without setup times. SelectLine preheating types and length can be configured individually. The soldering area – the heart of the system – also scores highly thanks to its outstanding flexibility. Several solder pots with different solder nozzles, either completely wetted or a directed solder flow to one side, can be integrated. They work in parallel and ensure maximum throughput. For small lot sizes and high mix of assemblies, different alloys can be processed without additional setup effort. A unique feature is the possibility to integrate an AOI system for solder joint inspections directly into the system – a big plus with regard to space and handling costs. The system offers a complete hardware and software package for automatic process control. It monitors flux amounts, including the actually applied amount, provides automatic position correction and z-height correction, controls the wave height and ensures MES integration. It is available both as an individually configurable modular inline solution and as a compact stand-alone model. 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. The company 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. The company also will exhibit the PowerWave N2 Nitrogen system for wave soldering and the new PowerReflow-2 which completes the product range for reflow solutions. The PowerSelective soldering system convinces with high-precision solder results and a flexible process for mini-wave and dip applications. The company also will launche ViproInline, an AOI module that can be integrated flexibly into a fully automated production line after the wave or selective soldering process to check assemblies for common THT solder faults as well as missing and misplaced components. And the MaxiReflow HP breaks new ground. This solution provides the ideal combination of convection heat and a special pressure module to obtain nearly void-free solder joints.
