Wash-Away Dissolvable Spacer Systems
Wash-Aways Spacer System AWP-75 is an organic polymer that dissolves in hot water or alcohol. After dissolving in most solvent baths that remove solder flux, AWP-75 leaves consistent spacing between PCB components and printed circuit boards.
AWP-75 contains no ionizable material, salts, sugars, metals, or soaps. It is non-corrosive, non-conductive, and non-toxic.
AWP-75 dissolving times depend upon Wash-Away spacer size and water temperature. Typical dissolving times are listed below:
