Soldering Fluxes
Soldering Fluxes for first-class wettability and reliability
Our range of soldering fluxes cater for specific demands of today’s SMT manufacturers, including high wettability, anti-bridging performance and low residue.
The Koki range of solder fluxes includes products that solve your particular challenges from bridging and residues to voiding. We can assist you with selecting lead–free, leaded or halogen-free solder fluxes with the required wetting performance and cleanability. The aim: repeatable solder joint reliability.
Specialist Applications include: VOC-Free wave soldering flux options, Tack Fluxes, Halogen Free Rosin based Leaded and un-leaded process applications.
Rosin Free, Ultra low residue wave soldering flux
Koki JS-EU-01 wave soldering flux
Made by special rosin-free preparation, achieving a beautiful finish with barely visible flux residues after soldering.
- By minimizing outflow of solid content due to the heat and pressure of waving, the flux remains active until the end of the process.
- Achieves remarkably consistent solder workability.
JS-EU-01 is ideal for soldering applications requiring:
- 4.0% solids content
- Ideally suited to wave soldering
- Flux type ORLO
- Minimal residues
- Excellent hole fill
- Low bridging
Rosin Free, Low residue wave soldering flux
Koki JS-EU-02 organic-acid based flux
Achieves excellent solderability, even in compact wave soldering machines with short pre-heating zones.
- Retains activation in long 2nd wave at high temperature, with excellent anti-bridging properties.
- With minimal solids content and resin additive, achieves exceptionally low flux residue.
JS-EU-02 is ideal for soldering applications applications requiring:
- 2.8% solids content
- Ideally suited to wave soldering
- Flux type ORLO
- Very low residues
- Maintains activation through long contact 2nd wave
Powerful wetting wave and selective soldering flux
Koki JS-E-15X wave soldering flux
Offers powerful wetting performance JS-E-15X and easily spreads uniformly over the whole surface to form a seamless flux layer.
- Complete removal of oxide film and prevention of reoxidisation during pre-heating ensure excellent through-hole filling.
- Compatible with severely oxidised materials such as nickel and brass, and effective for selective soldering.
JS-E-15X is ideal for soldering flux applications requiring:
- 14.8% solids content
- Ideally suited to wave soldering and selective soldering
- Flux type ROM1
- Powerful wetting
- Excellent hole fill
- Anti-bridging
- Anti-solder beading
Rosin Free, Low residue wave and selective soldering flux
Koki JS-EU-31 wave soldering flux
Offers excellent hydrophobicity compared to other organic acid based fluxes. It maintains high electrical reliability in prolonged humid conditions.
- Improved solder wettability and flux fluidity compared to other organic acid fluxes. Excellent workability like rosin type flux.
- Fast drying at room temperature, electrical reliability and workability make JS-EU-31 ideal for point soldering.
JS-EU-31 is ideal for soldering applications applications requiring:
- 2.7% solids content
- Ideally suited to wave soldering and selective soldering
- Flux type ORLO
- Halogen Free
- Low residue
- High humidity resistance
