Wash-A-Spacers are designed to accurately lift components off the surface of the circuit board during wave soldering. After soldering, they simply wash away in the cleaning cycle. Wash-A-Spacers are made of a unique blend of polymeric material contains no sugars, salts, metal, or soap. The result is a non-corrosive, non-toxic spacer that will not contaminate the circuit board. Wash-A-Spacers are available in a wide variety of shapes and thicknesses from 0.025 inches to 0.060 inches depending on the spacer design. They are an easy method for meeting the requirements of Mil Standard 275E.
Type P-75 is a 100% organic polymer similar to albumen in chemical composition. It dissolves in hot water (140°F, 60°C).
Wash-A-Spacers are ordered by the part number and thickness. The part number specifies the dimensions of the spacer design. The thickness is the dimension of the spacer off the surface of the circuit board. Thickness normally ranges from 0.025 inches to 0.060 inches, depending on the spacer design. The thickness tolerances for Wash-A-Spacers are +0.005 inches.
