Emil Otto expands flux gel range for PCB rework

Historically, separate fluxes with different activators were utilised for hand soldering and series production, potentially leading to cross-reactions.

Emil Otto's flux gels, featuring consistent activators akin to those in the brand's electronic fluxes, now welcome five new additions.

"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," stated Markus Geßner, Marketing and Sales Manager at Emil Otto GmbH.

The gels, such as FLUX GEL EO-B-010, align with their alcohol-based flux counterparts, including EO-B-010 A-C and X. This uniformity extends to other new gels like FLUX GEL EO-B-013, crafted from the electronic flux EO-B-013 and variants EO-B-013/X and XS, and FLUX GEL PM-334, based on flux PM-334 and its versions PM/EA-334 and PM/EA-2234. The offering also includes FLUX GEL RS-4004, paralleling flux RS 4004, and FLUX GEL EO-Y-014, mirroring the hybrid flux EO-Y-014 and its variants EO-Y-014 A-C.

These ‘No Clean’ gels are distinguished by their high concentration, activity, and commendable wetting and spreading properties. They assure superior soldering outcomes, activating even contaminated pads and component pins without crystallisation or inhomogeneity. They leave no sticky residues post-application.

Application of these gels is precision-engineered, utilising metering syringes and metal needles for pinpoint placement. Compatible with hot air or soldering iron techniques, these gels maintain their homogeneity and stability during processing.

Emil Otto will display these flux gels and more innovations at productronica in Munich from 14—17 November in Hall A4, Booth 315.
