Flux gels are frequently used for rework on assembled PCBs. In the past, this often meant relying on flux for hand soldering and repair soldering. These contained other activators, which were used for series production. The flux gels developed by Emil Otto are based on uniform activators 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 that offers products on a uniform activator basis, from flux concentrate to finished flux and flux gel. Using the same activators avoids cross-reactions that can occur when using different activators from different manufacturers. Due to the high demand, we have now decided to develop further flux gels on the existing flux base," explains Markus Geßner, Marketing and Sales Manager 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 flux gels are developed on the same principle. Other flux gels are also based on the same principle, using existing alcohol-based fluxes. FLUX GEL EO-B-013, for example, is manufactured with the electronic flux EO-B-013 and its variants EO-B-013/X and XS. The same applies to FLUX GEL PM-334, which is using flux PM-334 and the variants PM/EA-334, PM/EA-2234, and

FLUX GEL RS-4004 with flux RS-4004. All gels are highly concentrated and are characterized by high activity as well as good wetting and spreading. This also applies to FLUX GEL EO-Y-014. The gel is the only new product of the flux gels based on the alcohol-water-based hybrid flux EO-Y-014 as well as variants EO-Y-014 A-C.

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

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