Dissolvable Spacers Tout Consistent Spacing Between Components and PCB
Multi-Seals Inc. introduced Wash-Away dissolvable spacers, designed to provide consistent spacing between printed circuit boards and PCB components. These organic polymer spacers locate PCB components during soldering operations. After soldering, Wash-Aways dissolve in water or alcohol solvent baths. 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 PCB components, including resistors, capacitors, transistors, potentiometers, and integrated circuits. Wash-Aways contain no ionizable material, salts, sugars, metals, or soaps, and they are non-corrosive, non-conductive, and non-toxic.
