Emil Otto and Feinhütte – Cooperation of two excellent companies with tradition
Emil Otto GmbH and Feinhütte Halsbrücke GmbH will from now on support each other in sales and product development.
At present, Feinhütte Halsbrücke offers a wide range of different soft solders for all standard applications. The product portfolio includes soft solders for standard temperature profiles as well as for the low and high temperature range.
Thereby high attention is paid to the quality of the solders. Thus, only metals with a minimum purity of 99.9% are generally used for the production of lead-free soft solders. Customers can obtain ingots, bars and many other types of solder, which can be used in all common wave, selective and hot air tinning systems. In addition, solder wires are produced. These can be supplied in different thicknesses, as solid or flux-filled wire.

Applications:
- PCB manufacturing
- PCB assembly
- Cable assembly
- Measuring instruments manufacturing
- Medical technology
- Automotive



Wired and in shape
The centuries-long history of Feinhütte Halsbrücke and the associated expertise has enabled the company to produce almost all soft solder alloys by extrusion.
Our own innovations and close cooperation with the actual customers as well as our own quality commitment formed the solid foundation of our success. For example, wire diameters ranging from 0.23mm for SMD soldering to extruded rods with a cross-section of up to 22.0mm are part of the portfolio.
And of course, both the alloys and the fluxes themselves are standardised throughout and always subject to the highest quality requirements.
