Wash-Aways Dissolving Spacer System AWP-75 is an organic polymer that disintegrates 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.
Unlike salt spacers, sugar spacers, or soap spacers, 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:
|TYPICAL DISSOLVING TIMES*|
|Diameter**||.070"||2-6 Seconds||3-9 Seconds||-|
|.140"||5-10 Seconds||7-18 Seconds||10-52 Seconds|
|.370"||6-18 Seconds||16-36 Seconds||25-80 Seconds|
|*Dissolving times in hot water (140°F. Alcohol requires longer rinses.|
|**Many other configurations are available.
