Multi-Seals Wash-Aways™ dissolving spacers are organic polymer rings, wafers, rectangles, and blocks that disintegrate in hot water or alcohol. Our dissolvable spacers locate and reinforce PCB components during soldering operations. After soldering is complete, the printed circuit board spacers wash away in most water or alcohol solvent baths that remove solder flux. Dissolved standoffs leave 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 and industries, including transistors, capacitors, LEDs, potentiometers, integrated circuits, and other components used in printed circuit board assembly. Wash-Aways contain no ionizable material, salts, sugars, metals, or soaps, and they are non-corrosive, non-conductive, and non-toxic.
Multi-Seals offers engineering samples at no charge for your qualification. We will also conduct a free evaluation of your component for spacing with our water soluble standoffs. Contact us today to discuss your requirements.
