Alcohol based flux


Low-solids flux for wave, selective, and manual soldering with halogen-free activators (WEEE/RoHS conformant)
DIN EN61190-1-1: (IEC OR/L0) or type 2.1.3.A under ISO 9454
Appearance: colourless to bright yellow, clear liquid
Solid content:3.0 wt% (about 24 g/L)
Density at 20 °C: 0.800 (±0.003)
Acid number: 18.0 mg to 21.0 mg KOH/g
Activators:carboxylic acids
Solvents:Mixture of monohydric alcohols
Flash point:12 °C
In addition to application on wave soldering machines, EO flux EO-B.001 can also be used for selective and manual soldering. In this connection application can be done with a brush.

The EO flux dosing pen FA-334 or the EO Electronic Kit offer better dosing possibilities. Practice has shown that with proper application, the washing of circuit boards soldered with this flux can be largely dispensed with.
