Soldering Fluxes — Professional Materials for Electronics Manufacturing and Repair
Soldering flux is a critical process material that ensures proper solder wetting, removal of oxide films from metal surfaces, and overall stability of electronic assembly operations. Our catalog includes fluxes for mass production, DIP assembly (through-hole soldering), SMT technologies, as well as hand soldering, repair, and rework applications.
We offer proven solutions, including Interflux (Belgium) soldering fluxes, which have been successfully used for over 10 years in the contract electronics manufacturing operations of Electronic Technology LLC — from wave soldering processes to rework and repair tasks. This practical experience ensures stable quality, process repeatability, and compliance with modern electronics industry standards.
Selecting the right flux helps:
-
reduce soldering defects;
-
improve wetting on challenging surface finishes (OSP, ENIG, etc.);
-
increase long-term reliability of electronic assemblies;
-
optimize manufacturing efficiency and service operations.
Flux Selection Guide
| Soldering process | Recommended flux type | Key requirements | Typical application |
|---|---|---|---|
| Wave soldering | No-clean or VOC-free flux | Process stability, minimal residues | High-volume DIP production |
| Selective soldering | Low-residue specialized flux | Precise deposition, controlled activity | Automated selective soldering |
| Reflow soldering (SMT) | Flux within solder paste or liquid flux | Clean post-solder surface | Mass SMT assembly |
| Jet / spray fluxing | Liquid flux with controlled viscosity | Uniform application | Automated soldering lines |
| Hand soldering | Gel or alcohol-based flux | Ease of use, easy cleaning | Assembly and repair |
| Rework & repair | Active rework flux | High activity, localized application | Electronics servicing |
| OSP soldering | Specialized active flux | Compatibility with sensitive PCB finishes | Modern PCB manufacturing |
