Technical Data | November 2016 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL Product Description 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL is an XYZ-electrically conductive pressure sensitive adhesive (PSA) conductive tape. 3M tape 9709SL consists of a unique conductive matrix (highly loaded silver based conductive fillers) that allows for an electrically conductive PSA for good grounding and attachment to desired surfaces. The product is an acrylic based adhesive solution and offers good adhesion and grounding performance to many surface types. 3M tape 9709SL helps improved electrical performance and reliable small size contacts in a thin format. It is useful for grounding, PSA attachment and EMI shielding designs. Key Features • XYZ-conductivity through the adhesive • Unique silver based fillers provide for unique grounding performance of flexible circuits • Excellent conformability and quick bonding • Good EMI shielding in bond line gap • 50 µm thickness to conform to non-flat surfaces • Unique acrylic formulation provides compatibility to many surface types • Improved electrical contact to small size areas • Good handling and workability • 3M™ Electrically Conductive Adhesive Transfer Tape 9707 is the high adhesion version of 3M tape 9709SL (medium adhesion) • 3M tape 9709SL uses premium low peel force release liners Product Construction / Materials Descriptions Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL Property Color Face side Back side Value Gold metallic Gold metallic Conductive Adhesive Type Acrylic conductive adhesive with silver based fillers Release Liner Easy release side liner Tight release side liner 100 µm poly coated kraft (PCK) release liner 50 µm transparent PET release liner 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL Typical Physical Properties and Performance Characteristics Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.

ETM-12: Z-Axis Electrical Resistance through Adhesiveb Place conductive tape pieces in 10 mm x 10 mm on the center of the electrodes on 3M ETM-7 testing board. Then place 3M ETM-12 testing board with the gold plated side down on the tapes between electrodes. After initial hand lamination to provide for a 10 mm x 10 mm contact area between the tapes and electrodes, apply 2kg rubber roller across the tape one time. Application method simulates a typical manufacturing process that might be used to apply the tapes to a surface. After 20 minutes of dwell time, the DC resistance between the electrodes are measured with a micro-ohm meter. The resistance results are recorded after 5 ~ 30 seconds for initial resistance. Shielding Effectiveness Many factors determine the shielding effectiveness of a conductive adhesive tape, including type and thickness of the conductive layers, adhesive strength, degree of contact, smoothness of application surface and test frequency. For 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL, the typical shielding effectiveness is expected to be in the range of 30 dB to 50 dB, using a standard EMI shielding test methods and through the thickness of the sample tested. Applications 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL is typically used for applications requiring excellent electrical conductivity from the application substrate through the adhesive to a second substrate. Common uses include grounding and EMI shielding in equipment and components. 3M™ Electrically Conductive Adhesive Transfer Tape 9709SL End Use Application Techniques Note: Carefully read and follow the manufacturer’s precautions and directions for use when working with solvents. Tape application below 10°C (50°F) is not suggested. Once properly applied, low temperature holding power is generally satisfactory. The 3M™ Electrically Conductive Adhesive Transfer Tape bond strength depends on the amount of adhesive-tosurface contact developed during application and substrate type and surface conditions. 1. Firm application pressure helps develop better wet-out and adhesive contact and may lead to improved bond strength as well as electrical conductivity. Pressure must be applied to the bond area after assembly to ensure sufficient wet-out of the 3M tape 9709SL adhesive to the substrates and to engage the conductive acrylic adhesive fillers with the substrates to make electrical connection. Mechanical pressure (roller, metal bar) or finger pressure at 5-15 psi. (Optimally the application conditions are determined via a set of Design of Experiments (DOE) using a range of application pressures, dwell time and temperatures (suggested initial range might include 5-15 psi, 2-5 seconds, 21°C-38°C). 2. Heat may be applied simultaneously with pressure to improve wetting, final bond strength and electrical conductivity. Suggested temperature range to evaluate is in the 38°C-60°C range. 3. To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.
