Emil Otto presents an expanded portfolio of flux gels during productronica 2023

Flux gels are often used for repair work on assembled PCBs. In the past, it was often necessary to use fluxes for manual and repair soldering. These contained other activators, which were used for series production. The flux gels developed by Emil Otto are based on standardized activators that are contained in the previous electronic fluxes, thus avoiding cross-reactions. Emil Otto has now expanded this product portfolio with five additional gels.

"We are the only manufacturer to offer products on a standardized activator basis, from the flux concentrate to the finished flux and the flux gel. By using the same activators, cross-reactions that can occur when using different activators from different manufacturers are avoided. Due to the high demand, we have now decided to develop further flux gels on the existing flux base," explains Markus Geßner, Head of Marketing and Sales at Emil Otto GmbH.

FLUX GEL EO-B-010 is based on the same activator and the same active ingredient as the comparable, alcohol-based electronic flux EO-B-010 and its variants EO-B-010 A-C and X. The other flux gels are also based on the same principle and use existing alcohol-based fluxes. The FLUX GEL EO-B-013 is also based on the electronic flux EO-B-013 and its variants EO-B-013/X and XS. The same applies to the FLUX GEL PM-334which is based on the flux PM-334 and the variants PM/EA-334, PM/EA-2234, as well as the FLUX GEL RS-4004 with the flux RS-4004. All gels are highly concentrated and are characterized, among other things, by high activity as well as good wetting and spreading. This also applies to FLUX GEL EO-Y-014which is the only new flux gel product based on the alcohol-water-based hybrid flux EO-Y-014 and variants EO-Y-014 A-C.

All flux gels are "No Clean" gels. The gels achieve perfect soldering results and reliably activate even contaminated pads and component pins. No crystals are formed and the gels remain homogeneous and stable throughout processing. The residue behavior is also flawless. None of the gels leave sticky residues on the assembly. The gel is applied to all products from a dosing syringe using metal needles. These enable precise application and positioning of the flux gel. The gels are also processed in the same way using hot air or soldering irons.

Emil Otto will be presenting the new flux gels and other new products at productronica in Munich from November 14 to 17 in Hall A4, Stand 315.
