Product Description

3M™ XYZ-Axis Electrically Conductive Tape 9713 is an isotropically conductive
pressure sensitive tape. Tape 9713 conducts electricity through the thickness (Z-axis)
and in the plane of the adhesive (X, Y planes) and is ideal for EMI/RFI shield and
EMI/RFI gasket attachment to metal surfaces. The tape consists of a high performance
3M adhesive loaded with conductive fibers. The result is a double-sided ta pe providing
both good adhesion and good electrical performance. The conductive fibers in tape
9713 also provide improved handling characteristics.

XYZ-Axis Electrically Conductive tape 9713 is ideal for attaching EMI shields to
electronic and electrical devices. Tape 9713 may be used with many types of foil
laminate shields, such as aluminum/PVC or copper/PVC laminates, to provide a
customized shielding solution. This tape may also be used to attach conducti ve
fabric/foam core EMI gaskets to electronic cabinetry. Tape 9713 may be applied in
strips or die cut to specific shapes and sizes. Compared to screws or other mechanical
connectors, tape 9713 provides reduced assembly time and a solid bond line with no
gaps which might result in EMI emission.

Based upon four wire (Kelvin probe) resistance measurements made with
crossed pieces of Foil/9713/Rigid plate construction using a 1.0 in x 1.0 in
square piece of 9713. Room temperature aged for 1 year. The rigid metal
surface was prepared with a Scotch-Brite™ pad to roughen the surface
and cleaned with isopropyl alcohol.

Based upon a 90 degree peel sample, following ASTM D3330 test method. Aluminum foil (2 mil thick)
was used as the flexible backing to the tape 9713. The substrates listed are all rigid metal plates. The
158°F (70°C) aged peel samples are indicative of the typical long term adhesion build expected at room
temperature.
