Alcohol- and water-based fluxes for a wide range of applications
Alcohol- and water-based fluxes, also known as 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, particularly in terms of penetration and wetting of the circuit board. The process window is also very wide, with high thermal stability. The printed circuit boards are visually very clean after using the flux.
Emil Otto's hybrid fluxes for soldering combine the advantages of both water-based and alcohol-based fluxes in electronics production. They evaporate just as quickly as alcohol-based fluxes, but are just as environmentally friendly as water-based flux variants.
Hybrid fluxes therefore offer a perfect balance between high soldering quality, process stability and environmental friendliness. They are ideal for modern production requirements and enable companies to reduce both production costs and their environmental footprint.

The main advantages of alcohol- and water-based fluxes
Hybrid fluxes ensure optimal wetting of solder joints, leading to high soldering quality. This is particularly beneficial for complex electronic assemblies with small tolerances. The even distribution of spray flux improves the overall connection quality, ensuring strong and reliable joints.
Compared to purely alcohol-based fluxes, hybrid fluxes leave less residue on the assembly during soldering. As the need for subsequent cleaning can therefore be reduced or in some cases even completely avoided, production costs are reduced. In addition, minimal residues do not affect the electrical performance of the assemblies.
The alcohol components in hybrid fluxes promote rapid evaporation, reducing drying times. This is especially advantageous for high-speed production lines, where cycle time optimization is crucial.
Hybrid fluxes contain fewer flammable substances and contribute to a lower environmental impact than purely alcohol-based alternatives. Their formulation helps reduce volatile organic compounds (VOC) emissions, making them an ideal choice for manufacturers aiming to minimize their ecological footprint.
Hybrid fluxes are suitable for various soldering methods, including wave soldering, selective soldering, and manual soldering. Their universal usability makes them a versatile solution for modern electronics manufacturing.
Hybrid fluxes combine the advantages of both flux types and therefore offer greater process reliability. They reduce susceptibility to process fluctuations and enable consistently reliable soldering results - a decisive advantage for critical applications in electronics production.
Since hybrid fluxes require minimal cleaning and rework, they contribute to significant cost savings. Additionally, their ability to support multiple soldering processes simplifies logistics and inventory management, making them a cost-effective choice for the electronics industry.
In view of the increasing switch to lead-free soldering processes, hybrid fluxes offer a high-performance solution that meets specific requirements. The advantages of hybrid fluxes are particularly evident in environments that must comply with strict environmental and safety regulations.
