3M™ XYZ / Isotropic Electrically Conductive Adhesive
Transfer Tape 9707
Product Description
3M™ Electrically Conductive Adhesive Transfer Tape 9707 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 9707 has inherent EMI shielding capability.
Tape 9707 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 9707 can be applied as
die cut parts or in roll form.
Tape 9707 offers good XYZ electrical conductivity performance with good adhesion. As Tape 9707 has inherent EMI
shielding performance, it can enhance existing shielding solutions, offer new design options and improve Faraday cage designs.
Tape 9707 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 9707 to evaluate which will
work best given their product design. In some designs, Tape 9709 may perform effectively equivalently to Tape 9707 in
EMI shielding as a final design is electromagnetic interference compatibility (EMC) tested as a completed assembly.
Tape 9707 is a more surface aggressive ECATT on many substrates, which will allow a higher level of adhesion build as
measured via a peel adhesion test method and as compared to the Tape 9709S. As Tape 9707 is a more surface aggressive
ECATT tape, it is generally not compatible with Indium Tin Oxide (ITO) coating or other easily corroded surfaces.
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.
