The flux must allow for controlled tin plating so that only the specified length of the strand is wetted. At the same time, it must not damage the cable or strand insulation, nor have a corrosive effect on the resulting connection.
Solar panels should be cleaned especially after the pollen season in the spring. During this time, large amounts of pollen often accumulate on photovoltaic panels. Regular visual inspections and cleaning with suitable cleaning agents, such as photovoltaic cleaners from Emil Otto, can help maintain the system’s performance.
Solar fluxes help ensure stable and durable solder joints in cell bonding. Optimized flux technology can have a positive impact on process reliability, electrical reliability, and long-term module performance.
Nitinol is used in numerous military and aerospace applications, particularly where conventional materials reach their limits. These include adaptive structures in UAVs and missiles, thermally controlled actuators and valves, vibration and shock absorption systems, miniaturized microactuators, and reliable separation mechanisms in satellite technology. These applications benefit directly from unique properties such as shape memory and superelasticity.
Emil Otto's cleaning products are specially developed for cleaning photovoltaic systems. They gently remove typical contaminants such as pollen, dust, and organic residues from the module surface. This allows solar modules to be cleaned efficiently without damaging glass surfaces or coatings.
A suitable flux must selectively remove the titanium oxide layer, activate surfaces that are difficult to wet, and at the same time minimize corrosive residues. In addition, high process stability, low-residue processing, and suitability for automated manufacturing processes are crucial. Ideally, it should be zinc- and halide-free, non-flammable, and VOC-free.
The right flux promotes uniform and controlled tinning of the strands and improves wetting with the solder. At the same time, it is essential to ensure that neither flux residue nor flux penetration into the cable or strand insulation compromises the subsequent reliability of the connection.
Any remaining flux residue must not impair the electrical performance or long-term functionality of the cable connection. Of particular concern are potential corrosion and an excessively low surface electrical resistance (SIR).
The switch to water-based fluxes is a strategic decision aimed at reducing risks in the supply chain and stabilizing production costs. By eliminating alcohol-based solvents such as IPA and ethanol, companies can insulate themselves from highly volatile raw material markets. Emil Otto offers a technologically advanced portfolio for this purpose that combines high process reliability, reproducible soldering quality, and economic advantages.
Professional cleaning products are specifically designed to meet the requirements of photovoltaic systems. They remove contaminants such as pollen or dust without damaging the module surface. One example is Emil Otto’s range of cleaning products, which were developed for use in the solar industry.
