3M™ XYZ / Isotropic Electrically Conductive Adhesive
Transfer Tape 9709S / 9709 SL
Product Description
3M™ Electrically Conductive Adhesive Transfer Tape 9709S is a pressure sensitive adhesive (PSA) transfer tape with
isotropic electrical conductivity. The PSA matrix is filled with conductive fillers which allow interconnection between
substrates through the adhesive thickness (the “Z-axis”) and also provides electrical conductivity in the plane of the
adhesive (“X-Y Axis”). The PSA tack and adhesion properties allow for room temperature application and assembly
processes. Tape 9709S has inherent EMI shielding capability.
Tape 9709S provides an electrical connection and adhesively bonds EMI/RFI shields and gaskets to metal frames and
enclosures. The low contact resistance and tape construction result in good EMI performance. Tape 9709S can be applied
as die cut parts or in roll form.
Tape 9709S offers good XYZ electrical conductivity performance with good adhesion. As Tape 9709S has inherent EMI
shielding performance, it can enhance existing shielding solutions, offer new design options and improve Faraday gage designs.
Tape 9709S can offer lower contact resistance to “hard surfaces” or surfaces with oxide layers, such as to stainless steel as
compared to the Tape 9709. As each application is unique, it is important for users of the Tape 9709S to evaluate which
will work best given their product design. In some designs, Tape 9709 may perform effectively equivalently to Tape 9709S
in EMI shielding as a final design is electromagnetic interference compatibility (EMC) tested as a completed assembly.
3M™ Electrically Conductive Adhesive Transfer Tape 9709SL is a premium low release liner version of Tape 9709S. The
Tape 9709S standard release liners (PET/PET) offer good release properties from many common surfaces. In applications
where very low liner release is desired, the Tape 9709SL version offers a set of premium low release liners (PET/PCK Paper).
As in all conductive PSA applications, stable electrical performance in any electrical connection application may require
added mechanical reinforcement (clamping or compressing) in the bond area.
