SEHO: Modular soldering System
Modular soldering system.
Erlanger, KY — SEHO's SelectiveLine, is a modular system concept for mini-wave soldering that may be adapted to changing production conditions at any time. With low production quantities, for example, only the SelectiveLine solder module is required. With increasing throughput requirements or very massive products, the unit can be individually expanded by adding coordinate fluxer modules, preheater modules or even another SelectiveLine solder module. Consequently, cycle times are significantly reduced.

Conversely, the production line can be reduced in size again with end-of-line products and falling numbers by taking modules out of the line and using them for other products.

Using a high-precision mini-wave process, the SelectiveLine is well suited for a high product mix, offering maximum flexibility. The system has a precise axis system for exact positioning of various workstations and is capable of handling either bare boards or assemblies in carriers up to 500 x 500mm.

The automatic circuit board position correction via fiducial recognition ensures maximum precision and process reliability.

Various types of misalignment, such as offset, position error and linear distortion of the circuit board, are compensated for. Incorrectly positioned assemblies are detected and not soldered.

The soldering unit can be changed quickly if different alloys need to be processed. To minimize change-over times, a second soldering unit can be preheated on an external heating station prior to installation in the machine. Thus, changing to a different solder alloy only takes a few minutes.

The SelectiveLine is equipped with an up-to-date control unit, which is very simple to operate using a color touch screen. With the cutting-edge offline teaching program, soldering programs can be taken over by the machine using a USB memory stick or network connection without any further conversion.

The route optimization is particularly innovative. After being taught all the solder points, the program independently calculates the quickest path to keep pure handling times to a minimum.

Additional automatic control functions include automatic solder wave height control, real quantity control for drop jet fluxers, a scanning unit to allocate the installed solder wire reel to the corresponding soldering program, and a barcode reading system.
