Alcohol- and water-based fluxes for a wide range of applications
Alcohol- and water-based fluxes, also called hybrid fluxes, have been developed for use in wave and selective soldering. These fluxes have a very wide range of applications with very good soldering properties in particular with the step-through and the wetting of the circuit board. The process window is very wide with high thermal stability. After the application of the flux the circuit boards are visually clean.
Emil Otto’s hybrid fluxes combine the advantages of both water-based and alcohol-based fluxes in electronics manufacturing. They evaporate just as quickly as alcohol-based fluxes, but are as environmentally friendly as water-based alternatives.
Hybrid fluxes therefore offer a perfect balance between high soldering quality, process stability and environmental friendliness. They are ideally suited to modern production requirements and enable companies to both reduce production costs and lower their ecological footprint.

Hybrid fluxes provide excellent wetting of the solder joints, resulting in higher soldering quality. This is particularly advantageous for complex electronic assemblies with small tolerances. Since hybrid fluxes promote the even spreading of the solder, they improve the connection quality.
Compared to pure alcohol-based fluxes, hybrid fluxes leave less residue on the assembly. This reduces or in some cases even eliminates the need for subsequent cleaning, resulting in lower production costs. Furthermore, minimal residues do not affect the electrical performance of the assemblies.
The alcohol components in hybrid fluxes ensure that they evaporate quickly, which contributes to a shorter drying time. This is particularly advantageous in fast-running production lines, as the cycle times can be optimized.
Hybrid fluxes contain fewer flammable substances and have a lower environmental impact than purely alcohol-based variants. The formulation helps to reduce the emission of volatile organic compounds (VOC), which minimizes the ecological footprint of production.
Hybrid fluxes are suitable for a wide range of soldering processes, including wave soldering, selective soldering and manual soldering. Their universal application makes them a versatile solution for different production requirements.
Hybrid fluxes combine the advantages of both flux types and therefore offer a higher level of process reliability. They reduce the tendency towards process fluctuations and enable consistently reliable soldering results – a decisive advantage for critical applications in electronics manufacturing.
Hybrid fluxes require less rework and cleaning, which results in significant cost savings. In addition, the electronics industry benefits from the flexibility of being able to cover several soldering processes with a single flux. This simplifies warehousing.
As the transition to lead-free soldering processes accelerates, hybrid fluxes provide a powerful solution that meets specific requirements. The advantages are particularly apparent in environments that have to comply with strict environmental and safety regulations.
