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.

Optimum wetting and soldering results

Hybrid fluxes offer excellent wetting of the solder joints, which results in a higher soldering quality. This aspect is particularly advantageous for complex electronic assemblies with tight tolerances. As hybrid fluxes promote the even spreading of the solder, they improve the quality of the connection.

Reduced residues

Compared to pure alcohol-based fluxes hybrid fluxes leave less residue on the assembly during soldering. As this reduces the need for subsequent Cleaning or in some cases even avoided altogether, production costs are reduced. In addition, minimal residues do not affect the electrical performance of the assemblies.

Rapid evaporation

Thanks to the alcohol components, hybrid fluxes evaporate quickly, which contributes to a shorter drying time. This is a particular advantage in high-speed production lines, as cycle times can be optimized.

Environmental friendliness

Hybrid fluxes contain fewer flammable substances and are less harmful to the environment than purely alcohol-based variants. The formulation helps to reduce the emission of volatile organic compounds (VOCs), which minimizes the environmental footprint of production.

Flexibility in use

Hybrid fluxes are suitable for a variety of soldering processes, including wave soldering, selective soldering and hand soldering. Their universal applicability makes them a versatile solution for different production requirements in SMD soldering.

Process reliability

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.

Cost reduction

Hybrid fluxes require little rework and cleaning processes, resulting in significant cost savings. The electronics industry also benefits from the flexibility of being able to cover several soldering processes with a single flux. This simplifies stock-keeping.

Adaptation to lead-free processes

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.
