3M
1245
Embossed Copper Foil
3M 1245 is a 4 mil, deadsoft copper foil and aggressive acrylic adhesive. Common uses are grounding and EMI shielding. It is typically used for applications requiring excellent electrical conductivity from the application substrate through the adhesive to the foil backing. The copper foil backing solderable and reisits oxidation and discoloration. Many factors determine the true shielding effectiveness of a shielding tape, including type and thickness for foil, adhesive type, intimacy of contact, smoothness of application surface, strength and frequency of the EMI signal, etc.
