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.

General Information
Tape 9713 provides good adhesion to metal surfaces and provides low electrical
resistance that is stable over time. The pressure sensitive nature and fiber
reinforcement of tape 9713 makes this product convenient to use and tape 9713 also
has very good handling properties. Tape 9713 also has good liner release.
Application Ideas
• Attac
hing Foil Laminate EMI Shields
Tape 9713 is ideal for attaching foil laminate EMI shields to electronic and electrical
devices. These shields typicall y consist of either copper or alumin um foils lamina ted
to PVC. Tape 9713 provides good adhesion (initial and ultimate) as well as lo w
electrical resistance. Tape 9713 may be applied in strips or die cut to specific shapes
and sizes. Compared to screws or other mechanical connector, tape 9713 provides
reduced assembly time and a solid bond line with no gaps for EMI emission.
• Attac
hing EMI Gaskets
Tape 9713 may also be used for attaching EMI gaskets to electronic cabinets, such
as server cabinets or disk drive array cabinets. These gaskets typically consist of
conductive fabric over a foam core, and come in a variety of shapes and sizes. Tape
9713 may be cut into strips as narrow as 1/8 inch to provide adhesion for even the
narrowest of gaskets. Tape 9713 may also be pre-applied to the gasket for reduced
final cabinet assembly time.
Application Techniques
• To obtain maximum adhesion, the bonding surfaces must be clean and dry.
Isopropyl alcohol is recommended as a cleaning solvent.*
• Bond strength is dependent upon the amount of adhesive-to-surface contact
developed. This wetted area can be increased by applying tape 9713 firmly with a
roller or finger pressure to exclude air entrapment. Adhesion is optimized when the
substrates are flat or conformable substrates. Adhesion increases after application,
up to 24 hours later, due to increased wetting by the tape.
• Electrical performance is dependent upon the nature of the metal and its surface.
Most metal surfaces give enhanced electrical performance with tape 9713 when the
surface has been lightly abraded. Scotch-Brite pads are recommended for preparing
the metal surface.
• Tape 9713 should be applied between 60°F - 100°F (15 °C - 38°C). Tape application
below 50°F (10°C) is not recommended because the adhesive will be too firm to
wet the substrates, resulting in low adhesion. Warming the substrates to 100°F
(38°C) facilitates adhesion. Once properly applied, low temperature holding power
is generally satisfactory.
• Tape 9713 can be removed by separating the parts using torque for rigid parts or peel
for flexible ones. Remove the adhesive by pulling off as much as possible by hand.
Residual adhesive may be removed by rubbing with your finger or by application of
3M™ Packaging Tape over the residual adhesive followed by removal of the
packaging tape. The surfaces should be cleaned again before applying a new piece of
tape 9713. The force required to separate the parts and/or remove the adhesive can
be reduced by softening the adhesive by heating to 158°F -212°F (70°C - 100°C) or
using solvents such as acetone.*
*Note: Carefully read and follow the manufacturer’s precautions and directions for
use when handling cleaning solvents.

Application Ideas
ounding Computer Antistatic and Glare Reduction Screens
Computer antistatic and glare reduction screens need to be electrically attached to
the grounding mechanism. Tape 9713 penetrates through anti-smudge coatings
over the conductive layer to make an electrical connection. Placing tape 9713 along
the edges of such a screen provides many connection points to the antistatic coating
resulting in good electrical performance.
• Assemb
ly of EMI Cages in Telecommunications Equipment
Tape 9713 is ideal for assembly of an EMI cage to a printed circuit board, often
required in telecommunications equipment. The EMI cages are typically
constructed from aluminum frames and lids to protect components on the PCB
from EMI/RFI. The metal frame needs to be grounded to a wide copper trace
etched around the perimeter of the components to be protected. Tape 9713 is
applied as a die cut in the shape of the etched perimeter trace, then the frame is
bonded to the perimeter trace. Tape 9713 provides the shape of the etched
perimeter trace, then the frame is bonded to the perimeter trace. Tape 9713
provides for rapid assembly and grounding in one step. Compared with solder
attach or liquid conductive adhesive attachment of the EMIcage, tape 9713
reduces assembly time and exposure to elevated temperatures.
