(Cross talk, spurious EMI, signal degradation and noise.) Problem Solution Higher frequencies require optimized grounding and Faraday Cage design Inherent bond line thickness EMI Shielding using 3M™ Electrically Conductive Adhesive Transfer Tape (ECATT) Poor “through tape” EMI Shielding leads to lower EMI SE at High Frequencies. Standard electrically conductive tape leads to EMI leakage through bond line tape thickness. 60db 60dB EMI Shielding Flex Circuit (FPC) Flex Circuit (FPC) 3M ECATT 9709SL Flex Circuit (FPC) Flex Circuit (FPC) 3500 µm Metal Thickness Gap Size or Slit Length 35 µm 10Hz 0.1mHz 4 50mHz 1000mHZ 10000mHZ (1GHz) (10GHz) At High Frequencies, the effect of “through the tape thickness” EMI gaps or EMI slits is to allow EMI leakage. If the effective EMI gap/slit does not = “0”, EMI energy at high frequency can pass through a “standard conductive adhesive tape material” via the gap related to the adhesive thickness. The “Tape Bond Line Gap/Slit leakage effect” leads to poor EMI Shielding, cross-talk, degraded Signal-to-Noise ratio, etc. Grounding Surface Grounding (R OK)Surface (R OK) Grounding Surface Grounding (LowerSurface Contact(Lower R) Contact R) 3M ECATT with inherent EMI shielding at the bond line provides significantly reduced crosstalk, stray EMI, noise in circuit, antennae effects, FPC susceptibility and spurious emissions. 3M Electrically Conductive Adhesive Transfer Tape 9709SL used for FPC grounding and EMI Shielding Flex Printed Circuit Flex 3M ECATT 9709SL Grounding Surface Substrate Layer 3M ECATT 9707, 9709S These long-lasting adhesive transfer tapes can eliminate the need for screws and mechanical fasteners – while allowing the use of lighter, more compact fabric and layered foil shielding materials. And, unlike other electrically conductive adhesives that can be messy and difficult to handle, 3M delivers advanced adhesive and conductive properties in an easy-to-use, pressure-sensitive tape that can be hand or machine applied and die cut to virtually any shape!

Testing of ECATT materials and the noted test substrates does not imply that the ECATT is suitable for an end use application of similar materials. End user is responsible to determine if an ECATT and substrate combination is fit for use in their intended end use application. Contact Resistance (R ohms) between a Gold Flexible Test Strip and a Gold Pad PCB panel using the 3M ECATT Adhesive Type Product ECATT Basic Comparative Reference Table: Based on the suggested “ECATT Selection Process”, the end user should identify 2-4 ECATT products to test in an application to determine fitness for use. As each application is unique, it is difficult to identify the “Optimum” ECATT product without testing the ECATT products in an end use assembly design. The ECATT Selection Process of “Good-Better-Best” ranks products as they might perform in a nominal application. As each ECATT may employ different conductive particles, scrim or non-woven, thickness variations, acrylic adhesive type, etc., they will perform differently based on end use application – hence the need for the end users’ own comparative testing. The following technical information and data should be considered representative or typical and should not be used for specification purposes.
