    Product Overview

    Halogen-Free Flux

    Halogen-free flux is another important category aimed at reducing corrosive residues and improving long-term reliability. By eliminating halogens such as chlorine and bromine, these fluxes help prevent electrical leakage, corrosion, and material degradation, making them suitable for sensitive and high-reliability electronics including consumer devices, automotive electronics, and telecom equipment.

    Low-Solids Flux

    Low-solids flux often associated with no-clean formulations contains minimal residue after soldering. This reduces or eliminates the need for post-solder cleaning, lowering production costs and avoiding issues related to residue buildup on fine-pitch components. Despite having reduced solid content, these fluxes maintain effective activation to ensure proper wetting and minimal soldering defects.

    High-Compatibility Flux

    Lastly, high-compatibility flux is engineered to work across a wide range of solder alloys, PCB finishes, and manufacturing processes. These fluxes provide consistent performance in reflow, wave, and selective soldering, making them ideal for manufacturers seeking flexibility and process stability.

    With optimized chemistry and performance, electronic flux continues to be an essential material for achieving high-quality, reliable, and efficient electronic assembly.
