Soldering Fluxes
Engineered for precision. Formulated for performance.
Emil Otto offers a wide portfolio of fluxes tailored to modern soldering applications, including:
• No-Clean Fluxes – Halogen-free formulations for minimal residue and high reliability
• Alcohol-Based & Water-Based Fluxes – Designed for wave, selective, and hand soldering
• Specialty Fluxes – For solar tabbing, stringing, and high-temperature applications
• SMD-Compatible Fluxes – Optimized for reflow and SMT processes
Whether you’re working with PCBs, solar modules, or fine-pitch components, Emil Otto fluxes deliver consistent wetting, low residue, and excellent solder joint integrity.
Cleaning Chemicals
Cleanliness is reliability. Emil Otto makes it effortless.
Their cleaning agents are formulated to meet the highest standards in electronics manufacturing:
• Flux Removers – Effective on rosin, resin, and no-clean residues
• Stencil & Screen Cleaners – For SMT and hybrid assembly lines
• Board Cleaners – Safe for sensitive components and substrates
• ESD-Safe Cleaning Products – For static-sensitive environments
Emil Otto cleaning solutions help maintain process stability and product quality.
