High reliability. Competitive pricing.


We can guide you expertly through the new generation of soldering products from KOKI, a global leader in soldering product innovation, including leaded and unleaded solder pastes, fluxes, wires and adhesives for today’s high-temperature applications.

The Koki range of solder pastes includes products that solve your particular challenges, from pillowing and bridging to poor wetting and voiding. We can assist you with selecting lead–free, leaded or halogen-free solder pastes with the required process performance and cleanability. The aim: repeatable solder joint quality and reliability.

Solder pastes


Our range of solder pastes includes products offering excellent wetting performance and cleanability, as demanded by higher-temperature applications.

Solder fluxes


Our range of solder fluxes cater for specific demands of today’s SMT manufacturers, including high wettability, anti-bridging performance and low residue.

Solder wires


Our range of solder wires is designed to address needs including low spatter, low residue and reduced tip carbon build-up or erosion.
