Product Overview

ALPHA 856 is formulated for defect-free soldering in processes employing water cleaning. It has a buffered activation system containing no free acid, and has a neutral pH. Its post-soldering residues are also non-acidic.

ALPHA 856 is a low-smoking, efficient foam flux. Using moderate air flow rates, its fine-bubble foam head is fast breaking and recovers rapidly for effective coverage at high production speeds.

This highly active flux will produce bright, shiny connections, even if cleaning is delayed for several hours. ALPHA 856 flux residues remain water soluble and no corrosion products are visible.

Neutral pH Water Soluble Flux

ALPHA 856 is an intermediate-activity flux based on water soluble resin and does not contain organic acid activators. This flux can be effectively cleaned with plain water to very low levels of ionic contamination. Water washing can be done without the use of rinse aids, and with little or no foaming.

The ALPHA 856 flux is formulated so that the cleaning process water effluent is completely biodegradable, eliminating the needs of pH adjustment before disposal.
