The FE510052890 is an EMI Conductive Shielding Tape with 1.4-mil embossed copper foil backing, an acrylic pressure-sensitive adhesive and liner. Embossing makes excellent contact through the adhesive. The unplated copper is for non-corrosive conditions. The edges of the embossed pattern pressed into the foil cut through the adhesive layer to establish reliable metal-to-metal contact between the backing and the application substrate.
