Multi-Seals has 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, the spacers dissolve in water or alcohol solvent baths. This leaves uniform spacing between components and boards, which provide free circulation of air, mechanical protection, optimum filleting, and high accessibility for inspection, cleaning, and conformal coating.
The spacers are available in a range of sizes and shapes to accommodate a variety of PCB components, including resistors, capacitors, transistors, potentiometers, and integrated circuits. The spacers contain no ionisable material, salts, sugars, metals, or soaps, and they are non-corrosive, non-conductive, and non-toxic.
