Solar flux for reliable production

Emil Otto offers a broad portfolio for the soldering of solar modules, tabber and stringer material as well as the connection of cells. This includes flux, rinsing and cleaning agents as well as tubular solder. 

The fluxes are No Clean products that are formulated halogen-free. All fluxes leave no sticky residues. Process tests with well-known machine manufacturers from the stringer technology sector prove this. Furthermore, the activators are specially designed for the high temperatures required in the manufacture of solar modules without impairing the efficiency of the activators. This also applies to the actual application in particularly sunny and hot regions.

Solar fluxes: Optimal solutions for the solar industry

Advantages of solar fluxes from Emil Otto

Efficiency

High wetting and excellent soldering results ensure stable connections and therefore a longer service life for the solar modules.

Versatility

The fluxes are equally suitable for soldering solar modules as well as for tabber and stringer material.

Environmental friendliness

Our Solar Flux products are halogen and solvent-free. This protects both the environment and the health of workers.

Process reliability

The high purity of the soldering flux ensures that there are no impurities that could impair the function of the solar cells.

Optimal process solutions

Fluxes from Emil Otto can be used for both automated and manual soldering processes. The soldering fluxes offer stable results at high temperatures and ensure excellent wetting of the surfaces to be soldered. The electrical contacts of the solar cells are thus permanently and reliably connected, resulting in higher energy efficiency
