Product Description

™

Electrically Conductive Cushion Gasket Tape

3M™ Electrically Conductive Cushion Gasket Tapes ECG8035H, ECG8055H, and ECG8075H are electrically conductive

compressible gasket tapes in a double coated tape format with good electrical conductivity and excellent cushion/

recovery properties. The 3M ECG8000H Series tapes offer excellent gap filling performance while maintaining good

electrical grounding potential. These products offer conductivity through the thickness (Z-axis) & in the plane of the

adhesive (X-Y planes) and are ideal for EMI/EMC gasket tape applications between common substrates, such as

metal surfaces (including metal plated substrates). These products consist of a soft & conductive polymeric foam

gasket and thin electrically conductive adhesive tapes laminated on both sides of the cushion gasket. The conductive

adhesive is a high performance 3M™ Electrically Conductive Adhesive Transfer Tape (ECATT).

The 3M ECG8000H Series tapes are useful for EMI/ RFI shielding & grounding in electronics and electrical devices.

The 3M ECG8000H Series tapes may be applied in strips or die cut to specific shapes and sizes. Compared to screws

or other mechanical connectors and grounding means, the 3M ECG8000H Series tapes can provide for reduced

assembly time and a solid bond line with no bond line gaps which might result in EMI emissions.

The 3M ECG8000H Series tapes are supplied in a dual sided removable liners configuration for easy handling and die-

cutting properties. 3M ECG8000H Series tapes are available in standard size and custom sizes (widths and lengths).

Application Techniques

• To obtain maximum adhesion, the bonding surfaces must be clean and dry. Isopropyl alcohol is suggested as a cleaning

solvent.*

• Bond strength is dependent upon the amount of adhesive-to-surface contact developed during application. The

wetted contact area can be increased by applying 3M™ Electrically Conductive Cushion Gasket Tapes ECG8035H,

ECG8055H, and ECG8075H firmly with a roller or finger pressure to exclude air entrapment. Adhesion is optimized

when the substrates are flat or conformable substrates.

• Electrical performance is dependent upon the nature of the substrate surface finish and surface type (Stainless steel,

Aluminum, etc.). Most metal surfaces give enhanced electrical performance with 3M ECG8000H Series tapes when the

surface has been lightly abraded and cleaned. Scotch-Brite™ pads are suggested for preparing the metal surface.

• 3M ECG8000H Series tapes should be applied between 17°C - 35°C. Tape application below 10°C is not suggested

because the adhesive will be too firm to wet the substrates, resulting in low adhesion. Warming the substrates to 38°C

facilitates adhesion. Once properly applied, low temperature holding power is generally satisfactory.

• 3M ECG8000H Series tapes 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 is suggested. 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 3M ECG8000H Series

tape. The force required to separate the parts and/or remove the adhesive can be reduced by softening the adhesive by

heating to 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.

General Information

3M ECG8000H Series tapes provide good adhesion to most metal surfaces and provides good electrical resistance to

many substrates. The pressure sensitive nature and fiber reinforcement of 3M ECG8000H Series tapes make this product

convenient to use and 3M ECG8000H Series tapes also have very good handling properties including good liner release.

Application Ideas

3M ECG8000H Series tapes are typically used for applications requiring excellent EMI shielding, flexibility/gap filling in

the bond line, contact grounding and a mechanical cushion to protect from mechanical shock/vibration in the electronic

devices.

• Grounding Mobile Hand Held and Flat Panel Display.

• Key pads and display modules in Mobile Hand Held devices and Flat panel display as LCD and PDP need to be

electrically attached to the grounding mechanism.

• Assembly of EMI Cage, Metal Case & Frame in Modern Electronic Devices and High Speed Telecommunication

Equipment.

• Assembly of cover case and main frame parts

• EMI cage to PCB (printed circuit board). The EMI cages are typically constructed from aluminum frames and lids to

protect components on the PCB from EMI/RFI. 3M ECG8000H Series tapes are applied as a die cut in the shape of the

perimeter, then the frame is bonded to the perimeter trace.
