3M™XYZ-Axis Electrically Conductive Adhesive Transfer Tape

9719 for LSE Substrates and High Temperature Applications

Product Description

3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719 is a silicone adhesive isotropically conductive

pressure sensitive tape. Tape 9719 conducts electricity isotropically (X, Y, Z) and is suitable for low surface energy

EMI/RFI shield and EMI/RFI gasket attachment to metal surfaces. The double-sided Tape 9719 provides adhesion to low

surface energy substrates and performs at elevated temperatures for short periods (up to 400°F [204°C]). Tape 9719

utilizes conductive fibers to provide good electrical performance with improved handling characteristics.

Tape 9719 may be used with many types of foil laminate shields, to provide a customized shielding solution. This tape

may also be used to attach conductive fabric/foam core EMI gaskets to electronic cabinetry. Tape 9719 may be applied in

strips or die cut to specific shapes and sizes. Compared to screws or other mechanical connectors, Tape 9719 provides

reduced assembly time and excellent grounding between substrates for reduced EMI emissions.

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 9712. 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. Test results will vary with test method set-up, sample size tested, assembly methods,

aging, substrate types, product lot to lot normal variation, etc.

Application Techniques

• To obtain maximum adhesion, the bonding surfaces must be clean and dry. Isopropyl alcohol or non-polar solvent such as

Heptane or Toluene can be used as a cleaning solvent.*

• Bond strength depends on the amount of pressure used in the bonding process and mechanical properties of the substrate.

Adhesion can be optimized by using a roller or other means to reduce air entrapment and by using flat or conformable

substrates. Maximum adhesion is typically achieved after 24 hrs.

• Electrical performance can be optimized by abrading the surface of the metal using 3M™ Scotch-Brite™ pads.

• Recommended application temperature between 60°F - 100°F (15°C - 38°C).

• Tape 9719 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 9719. 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 Heptane or Toluene.*

*Note: When using solvents, extinguish all ignition sources and follow manufacturer’s precautions and directions for use.

General Information

3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9719 provides good adhesion to low surface energy

and/or other metal surfaces and provides low electrical resistance that is stable over time. The pressure sensitive nature and

fiber reinforcement of Tape 9719 makes this product convenient to use. It is easy to release from the liners and provides

good handling properties.

Application Ideas

•Attaching Foil Laminate EMI Shields

3M™ XYZ-Axis Electrically Conductive Tape Adhesive Transfer Tape 9719 is suitable for attaching foil laminate EMI

shields to electronic and electrical devices. These shields typically consist of either copper or aluminum foils laminated to

PVC. Tape 9719 provides good adhesion (initial and ultimate) as well as low electrical resistance. Tape 9719 may be

applied in strips or die cut to specific shapes and sizes. Compared to screws or other mechanical connector, Tape 9719

provides reduced assembly time and a solid bond line with no gaps for EMI emission.

•Attaching EMI Gaskets

Tape 9719 may also be used for attaching silicone EMI gaskets to electronic cabinets, such as server cabinets or disk drive

array cabinets. These gaskets typically consist of LSE conductive fabric over a foam core, and come in a variety of shapes

and sizes. Tape 9719 may be cut into strips as narrow as 1/8 inch to provide adhesion for even the narrowest of gaskets. Tape

9719 may also be pre-applied to the gasket for reduced final cabinet assembly time. In many cases, Tape 9719 eliminates the

need to chemically prime the LSE gasket, which is otherwise difficult to bond.

•Grounding Computer Antistatic and Glare Reduction Screens

Computer antistatic and glare reduction screens need to be electrically attached to the grounding mechanism. Tape 9719

penetrates through anti-smudge coatings over the conductive layer to make an electrical connection. Placing Tape 9719 along

the edges of such a screen provides many connection points to the antistatic coating resulting in good electrical performance.

•Assembly of EMI Cages in Telecommunications Equipment

Tape 9719 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 9719 is applied as a die cut in the shape of the etched perimeter trace, then the frame is bonded to the

perimeter trace. Tape 9719 provides for rapid assembly and grounding in one step. Compared with solder attach or liquid

conductive adhesive attachment of the EMI cage, Tape 9719 reduces assembly time and exposure to elevated temperatures.
