Anti-foam agents for safe processes during the removal of flux residues in electronics manufacturing

Neben einem breiten Portfolio von Reinigungsmedien für unterschiedliche Anwendungsbereiche in der Elektronikherstellung, bietet die Emil Otto GmbH nun auch zwei Antischaummittel an. Diese können bei der maschinenbasierten Reinigung eingesetzt werden, um eine unkontrollierte Schaumentwicklung zu vermeiden.

In addition to a broad portfolio of cleaning agents for various applications in electronics manufacturing, Emil Otto GmbH now also offers two anti-foaming agents. These can be used in machine-based cleaning to prevent uncontrolled foam development.

Etimol defoamers are effective anti-foaming agents for eliminating foam formation in aqueous cleaning media. They have proven to be particularly effective for use in automated cleaning where water-soluble flux residues can cause excessive foaming. This heavy foaming can cause valves within the cleaning system to become clogged and pumps to stop working and fail. The anti-foaming agents developed by Emil Otto are environmentally friendly and non-flammable and are therefore, like the other Etimol cleaning products, no dangerous goods.

At SMTconnect 2022, Emil Otto will present the two defoamers to the trade public for the first time. The ready-to-use Etimol defoamer DFL-100, for example, has been specially developed for the EO cleaners as well as the Etimol cleaning media to prevent foam formation during spraying and rinsing or to break up foam that has already formed. This extends the process window and compensates for the reduced cleaning performance due to process-related contamination. Furthermore, with Etimol Defoamer DFL-C, a concentrate was developed that also reduces and inhibits foam formation during foaming of the cleaning bath. This concentrate was also developed for the EO cleaners, especially for the ETIMOL cleaning media. The high-performance concentrate is very effective even in very small quantities.
