3M 1345 Tape features an embossed 1-ounce deadsoft tin-plated copper foil backing combined with a pressure-sensitive acrylic adhesive. This design allows for reliable metal-to-metal contact, enhancing electrical conductivity through the adhesive. The tape is supplied on a removable liner for ease of handling and die-cutting, and is available in various widths from 1/4,Äù to 23,Äù, with a standard length of 18 yards. The total thickness of the tape is 4.0 mil (0.101 mm), with a backing thickness of 1.4 mil (0.04 mm). It exhibits a breaking strength of 25 lb/in (44 N/10mm) and adhesion to steel of 45 oz/in (4.9 N/10mm). The electrical resistance through the adhesive is measured at 0.001 ohm, and the tape passes flame retardancy tests per UL 510. Common applications include grounding and EMI shielding in various equipment and environments. The tin plating on the copper foil backing aids in soldering and improves resistance to oxidation. The tape's typical shielding effectiveness ranges from 75dB to 95dB across frequencies from 30 MHz to 1 GHz, making it suitable for applications requiring effective electromagnetic interference protection.
