Flux for Wave Soldering
Ultra Low Residue Wave Soldering Flux
- JS-EU-31
The special resin formulation ensures that flux residue remains invisible after soldering, resulting in a clean, non-sticky finish. Its excellent solderability, including powerful wetting, helps prevent defects, making it suitable for a wide range of applications.
feature
- Low solids (4.0%) powerful wetting for general applications
- Superior solderability and through-hole holefill characteristics
- Drastically reduces bridging, blow holes, and solder balls
- Ultra-low residue for an excellent aesthetic appearance

Purpose of Use
Wave soldering
Hydrophobic residue prevents migration
By adopting a special rosin, JS-EU-31 achieved excellent hydrophobicity compared to regular organic acid based flux. Long exposure to humid conditions does not result in moisture absorption, and thus high electrical reliability is maintained. Migration and discoloration are effectively prevented.
Excellent solder workability
Poor solder wettability and poor flux fluidity have always been a concern of organic acid type flux.
Improvements have been made on these factors in JS-EU-31, achieving excellent solder workability just like rosin type flux.
Fast drying at room temperature : ideal for point soldering
Insulation resistance quickly recovers just by being left at room temperature, due to the high drying rate of the solvent.
Along with its high electrical reliability and excellent solder workability, JS-EU-31 is suitable for local flowing with no pre-heating.
