Alcohol based flux


Low-solids flux for wave soldering with halogen-free activators
and low artificial resin content (WEEE/RoHS conform)
DIN EN 61190-1-1: (IEC RE/L0) or type 1.2.3.A under ISO 9454

Appearance:Colorless to amber-colored, clear liquid
Solid conten:1.8 wt.-%
Density (20 °C):0.793 (±0.003) g/ml
Acid Value:14-16 mg KOH/g
Activator:Carboxylic acid
Solvent:Mixture of monohydric alcohol
Flash point:12° C

This low-solid flux was developed for use in wave soldering machines and possesses a relatively high activity despite the low solid content of only 1.8%. Application can be undertaken in any conventional manner.

Practice has shown that with proper application, the washing of circuit boards soldered with this flux can be largely dispensed with. In contrast to ‘resin-free fluxes’, ‘GSP-1833’ is characterized by higher resistance values, so no cleaning is required. The ICT test with needle adapters is unproblematic.
