ALPHA® 856 Liquid Soldering Flux
A neutral pH, 15% solids, moderate to high-activity water-soluble flux, non-acidic and can sit in production before washing.
Contact UsProduct Overview
ALPHA 856 is formulated for defect-free soldering in processes that use water cleaning. It features a buffered activation system with no free acid and a neutral pH. Its post-soldering residues are non-acidic.
A low-smoking, efficient foam flux, ALPHA 856 uses moderate air flow rates to create a fine-bubble foam head that breaks quickly and recovers rapidly, providing effective coverage at high production speeds.
This highly active flux produces bright, shiny connections, even if cleaning is delayed for several hours. ALPHA 856 flux residues remain water-soluble with no visible corrosion products.
Product Features
Water Soluble, Neutral pH
Non-Corrosive Post-Soldering Residues
Biodegradable Effluent
Board Cleaning Can Be Delayed Post-Soldering
ALPHA 856 is an intermediate-activity flux based on water-soluble resin and contains no organic acid activators. It can be effectively cleaned with plain water to achieve very low levels of ionic contamination. Water washing can be done without rinse aids and with little or no foaming.
Formulated for environmental safety, ALPHA 856 ensures that cleaning process water effluent is fully biodegradable, eliminating the need for pH adjustment before disposal.
