Sustainable ecological soldering processes can be realized in various ways. Of course, the simplest option is to optimize the overall process in terms of energy requirements alone so that it consumes as little electricity as possible. However, sustainability of soldering processes also means saving solder and flux or using sustainable and resource-conserving consumables. Furthermore, an intelligent PCB concept can support sustainability. Optimized solder joints and or PCB designs reduce the use of energy and expendables.
Furthermore, the hardware used can optimize soldering processes in such a way that resources are saved or their consumption reduced. Energy savings can be achieved, for example, through a specially developed heating algorithm, the double-monitored solder bath temperature or through solder wave height control in mini wave solder modules. An intelligent cell concept can contribute to savings additionally. With modular cell concepts, the entire machine geometry and design can now be implemented according to sustainable aspects. Thus, scalable e-cells not only stand for efficient use of space as well as modularity with precision, but also for sustainability. For example, a grid dimension of 300mm in width and length makes it possible to individually adapt the size of each automation cell to a wide range of tasks. To implement a cradle-to-cradle principle more sustainably, the number of switch cabinets can be reduced and replaced by centralized as well as easily exchangeable cabinet solutions. As another part of this principle, machines used by the customer are taken back from the market and reused for new applications.
The E-cell with its modular design also makes this possible. In other words, old systems and modules are recycled for new applications. The thought process underlying this decision is simple: in addition to the working time, material values have also been incorporated in every delivered system, which can certainly continue to be used in new projects. These can be, for example, the production cell and kinematic solutions, but also soldering modules, solder nozzles, wire feeders or thermodes. If these parts are still functional, they can be reused.
The expendables used can have a lasting effect on soldering processes as well. For example, water-based fluxes. They not only stand for an ecological end product, but also for environmentally compatible production and simplified transport. The soldering results correspond to those achieved with alcohol-based fluxes. A switch to ecological, water-based fluxes is therefore possible without further difficulty.
In addition, it is possible to use ecologically sustainable products in the solders. For example, high-quality tin alloys have been developed that are obtained entirely from recycled materials and achieve purity levels of up to 99.99% through upcycling processes.
