Dissolvable spacers - Multi-Seals Inc.

 Wash-Away dissolvable spacers provide consistent spacing between printed-circuit boards and PCB components. The organic polymer spacers help position PCB components during soldering operations. Afterwards, they dissolve in water or alcohol baths. This leaves uniform spacing between components and boards, which improves air circulation, mechanical protection, filleting, and accessibility for inspection, cleaning, and conformal coating. The spacers are available in a wide range of sizes and shapes to accommodate a variety of components, including resistors, capacitors, transistors, potentiometers, and integrated circuits. Wash-Aways contain no ionizable material, salts, sugars, metals, or soaps, and they are noncorrosive, nonconductive, and nontoxic.
