Flux pastes for electronics production

The flux pastes are paste-like electronic fluxes. The pastes can be used for all types of manual and repair soldering. The application method depends on the process. For hand soldering, the paste can be dispensed directly with a syringe. Flux pastes are also suitable for dip tinning and special applications. Flux pastes can be applied using hot air and soldering irons, but also with a soldering tip.

Flux pastes from Emil Otto ensure optimum wetting of the soldering surfaces and guarantee long-lasting, high-quality connections.

Flux pastes consist of a combination of fluxes, binders and fillers. Their main function is to remove oxide layers from the surfaces to be soldered and to distribute the solder evenly over the contact surfaces. This ensures a secure and stable electrical connection.

As Emil Otto attaches particular importance to the composition of the pastes, an optimum soldering process and high solder joint quality are ensured. Users can choose from a wide range of flux pastes specially developed by Emil Otto for various soldering requirements.

The long-established company Emil Otto has been involved in the development and production of fluxes for decades. The flux pastes on offer are not only the result of sound research and development, but also offer numerous advantages:

High-quality materials: The flux pastes consist of carefully selected, high-quality raw materials. This means that the best results can be achieved with the flux pastes for every soldering process
Wide range of applications: Emil Otto's quality products are suitable for various soldering applications - from component production and cable assembly to microelectronics and the manufacture of solar cells.
Environmentally friendly options: Emil Otto attaches great importance to sustainability. Many flux pastes are halogen-free and meet strict environmental standards.

The fluxes are therefore characterized by a broad spectrum of added value:

Precise application

Thanks to their paste-like consistency, the fluxes can be applied precisely and evenly to the desired areas. This reduces the amount of material required and ensures clean solder joints.

Reduced cleaning effort

Many flux pastes from Emil Otto leave hardly any residue after the soldering process. This minimizes the cleaning effort and reduces production costs.

Optimal wetting

The pastes can be used to evenly wet soldering surfaces. This improves the quality of the soldered joints and increases the reliability of the assemblies.

Wide temperature range

The flux pastes are suitable for a wide range of temperatures and soldering processes. This enables flexible application in various manufacturing processes.

Emil Otto's innovative products enable companies in the electronics industry to optimize production processes, reduce costs and increase the quality of their products at the same time.
