In- and Offline Selective Soldering System for Future-Oriented Manufacturing Layouts


ERSA, the world wide technology leader in the field of selective soldering, enhances its portfolio with the ECOCELL, a system ideally suited for the new production methods contemplated by many users. With its counter-clockwise flow, the ECOCELL follows the Toyota principle. The U-shaped layout is ideal for users that plan to manufacture in production islands, yet it can also be integrated, through its side feed, into a production line.


In the ECOCELL, high throughput and high flexibility are not contradictory. With two preheaters integrated, up to 4 boards can be processed simultaneously, and if a second solder bath is added to the axis, panels can be soldered very efficiently. Likewise, when a single wave pot or two single wave pots are installed, different alloys could be made available on the system. This feature, as well as the possibility to perform maintenance or change nozzles on one of the bath while the other continues to operate, reduces production losses to a minimum.

The well-proven precision spray fluxing system is also installed in the ECOCELL. Thanks to the integrated spray stream monitoring feature, flux application, whether in points or in tracks, is performed with reproducible high quality.


The bottom-side short-wave IR emitters can be complemented with an optional upper convection preheater. This combination of preheats assures homogeneous heating of even the most complex PC boards. An optional convection heater mounted over the single wave solder bath maintains the board temperature during a lengthy solder cycle.


When soldering on the 0° level, bridging will not be a problem on account of the "peel-off" feature developed by ERSA, assuring lowest DPM’s. To deliver solder to the wave, induction pumps are used. Therefore, the baths require very low maintenance, and there are virtually no wear parts.

Programming of the system software is intuitively based and very effective and all relevant process parameters are recorded in accordance with the ZVEI standard (traceability). The graphical programming interface via the CAD Assistant 2 permits very fast and facile offline programming. It is not required that the system is taken out of production, assuring maximum availability of the system for production.
