AQUANOX A8830 cleans solder paste from stencil apertures in ultrasonic immersion cleaning tanks. A typical wash cycle using a 10% solution of A8830 at room temperature typically requires less than a 4-minute wash cycle and easily rinses with water, leaving no residue on stencil surfaces. AQUANOX A8830 effectively cleans all solder paste types including water-soluble, rosin, lead-free and no-clean formulas.
