Multi-Seals Wash-Aways Dissolving Component Spacers are organic polymer standoffs that dissolve in hot water or alcohol. These spacers locate and reinforce PCB components during soldering operations. After soldering is complete, Wash-Aways dissolve in most water-solvent baths that remove solder flux. This leaves uniform spacing between components and boards, which provides free circulation of air, mechanical protection, optimum filleting, and greater accessibility for inspection, cleaning, and conformal coating.
Wash-Aways are available in a wide range of sizes and shapes to accommodate a variety of components, including transistors, capacitors, LEDs, potentiometers, integrated circuits, and other components used in PCB assembly. Wash-Aways contain no ionizable material, salts, sugars, metals, or soaps, and they are non-corrosive, non-conductive, and non-toxic.
