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, test frequency, etc. For 3M tape 9711S series, the typical shielding effectiveness is expected to be in the range of 40 dB to 60 dB, using a standard EMI shielding test methods and through the thickness of the sample tested. 3M™ Electrically Conductive Double-Sided Tape 9711S Series Typical Operating Temperature Range for Acrylic-Based Pressure Sensitive Adhesives (PSAs) 3M acrylic conductive pressure sensitive adhesives (CPSAs) contain conductive fillers. The grounding and/or substrate interconnection performance of the conductive fillers within the acrylic PSA in an application will vary based on many factors including substrate types, contact grounding area, surface geometry in the bond line, flexibility of substrates, bonding conditions, applied voltage/current, application environment and environmental aging conditions-exposure. In general, the acrylic PSA polymer itself used in acrylic CPSAs have good short term and long term environmental stability with respect to the PSAs macro-adhesion performance to many substrates. The acrylic polymers typical long term (days-weeks) performance and short-term performance (minutes-hours) based on an adhesion test method is generally 85°C (185°F) long term and 121°C (250°F) short term. 3M CPSAs should be tested in the desired application to ensure the product is appropriate for use based on the application’s specific requirements, including substrate types, contact grounding area, surface geometry in the bond line, flexibility of substrates, bonding conditions, applied voltage/current, application environment and environmental aging conditions-exposure. Applications 3M™ Electrically Conductive Double-Sided Tape 9711S Series 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, components. 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 bond strength of 3M™ Electrically Conductive Double-Sided Tape 9711S Series depends on the amount of adhesive-to-surface contact developed during application and substrate type and surface conditions. 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 9711S series 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. 1) 3M™ Electrically Conductive Double-Sided Tape 9711S Series 3M ETM-7: XY-Axis Electrical Resistance through Adhesive Place a strip of the single (double) side conductive tape in 10 mm x 40 mm with adhesive side down between the electrodes on 3M ETM-7 testing board. After initial hand lamination to provide for a 10 mm x 10 mm contact area between the tape and electrodes, apply a 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. 3M ETM-12: Z-Axis Electrical Resistance through Adhesive 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.
