Dissolvable devices provide uniform spacing
Multi-Seals' Wash-Away dissolvable spacers are designed to provide consistent spacing between printed circuit boards and pcb components.
The 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 is said to provide free circulation of air, mechanical protection, optimum filleting, and greater accessibility for inspection, cleaning, and conformal coating.
Wash-Aways are available in a range of sizes and shapes to accommodate a variety of pcb components, including resistors, capacitors, transistors, potentiometers, and integrated circuits. According to Multi-Seals. Wash-Aways contain no ionisable material, salts, sugars, metals, or soaps and are noncorrosive, nonconductive, and nontoxic.
