1183 Tape Tin-Plated Copper Foil with Conductive Adhesive Data Sheet Product Description Applications 3M 1183 Tape is typically used for applications 3M 1183 Tape consists of a 1-ounce deadsoft requiring excellent electrical conductivity from tin-plated copper foil backing and a unique the application substrate through the adhesive to electrically conductive pressure-sensitive acrylic the foil backing. Common uses include adhesive. grounding and EMI shielding in equipment, components, shielded rooms, etc. The tin plating Deadsoft 1-ounce tin-plated copper foil facilitates soldering to the backing and resists backing oxidation and corrosion. Conductive acrylic adhesive Supplied on a removable liner for easy Shielding Effectiveness handling and diecutting Many factors determine the true shielding Like all 3M shielding tapes, 3M 1183 is available effectiveness of a shielding tape, including in standard and custom widths and lengths. type and thickness of foil, adhesive type, Standard length is 18 yards. intimacy of contact, smoothness of application surface, strength and frequency of the EMI Widths from 1/4 to 23 Longer lengths up to several times normal signal, etc. However, using standard tests and length, dependent upon width. Check with fixtures, it is possible to determine a value for Customer Service. the attenuation. For 3M 1183 Tape, typical shielding effectiveness (far field) is in the range of 70dB to 85dB (30 MHz to 1 GHz). Properties Typical Values 1 Backing thickness 1.4 mil (0,04mm) 2 Total thickness (backing plus adhesive) 2.6 mil (.066mm) 1 Breaking strength 25 lb./in (44 N/10mm) 1 Adhesion to steel 35 oz/in (3,8 N/10mm) 2 Electrical resistance through adhesive 0.005 ohm 3 Flame retardancy Pass * Footnote: 1. Test method ASTM D 1000 2 2 2. MIL-STD-202 Method 307 maintained at 5 psi (3,4 N/cm ) measured over 1 in surface area. Conductive particles in the adhesive provide the electrical path between the application substrate and the foil backing. 3.
