3M™ XYZ / Isotropic Electrically Conductive Adhesive
Transfer Tape 9709
Product Description
3M™ XYZ/Isotropic Electrically Conductive Adhesive Transfer Tape 9709 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 electrically
conducting in the plane of the adhesive (“X-Y Axis”). The PSA tack and adhesion properties allow for room
temperature application and assembly processes.
Tape 9709 is an excellent choice for EMI shield attachment and grounding applications. Tape 9709 offers good
adhesion to common substrates such as copper, aluminum, gold, stainless steel, FR-4 epoxy, Kapton® polyimide and
polyester films.
Tape 9709 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 9709 can be applied
as die cut parts or in roll form.
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.
