Double Sided Tapes

Ther-a-Grip

Double-sided thermal tapes adhere the heat sink to the device and offer good thermal characteristics. They are easy to apply, require no curing time, can be electrically conductive or isolating, and need no mechanical support to provide thermal or physical contact between the device and the heat sink. Aavid can apply one side to a heat sink.

Available in a specific cut size or in a sheet size, typically 8.00" x 8.00".

Ther-A-Grip™ 1050 / T404

For ceramic or metal packages
Ther-A-Grip™ 1050 uses a 0.001 inch (0.03 mm) Kapton MT filled polymide film coated on both sides with high-bond strength, pressure-sensitive acrylic adhesive that is loaded with aluminum oxide particles. This provides both good thermal performance and excellent electrical isolation.

Ther-A-Grip™ 1070 / T405R

For ceramic or metal packages

Ther-A-Grip™ 1070 uses a 0.002 inch (0.05 mm) aluminum foil core coated on both sides with high-bond strength, pressure-sensitive acrylic adhesive that is loaded with aluminum oxide particles. The aluminum foil provides added thermal conductivity for applications where electrical isolation is not required. The combination of filter, expanded metal and embossed surface enhances both tape conformability and thermal performance.


Ther-A-Grip 1090™ / T412

For ceramic or metal packages

Ther-A-Grip™ 1090 uses an expanded foil carrier coated on both sides with high-bond strength, presure sensitive acrylic that is loaded with titanium diboride particles. The combination of filter, expanded metal and embossed surface enhances both tape conformability and thermal performance.

T410R / T411


For plastic packages

T410R thermally conductive tape consists of a high bond strength, pressure sensitive acrylic adhesive loaded with aluminum oxide and coated onto a 0.002 inch (0.05mm) aluminum foil carrier. The other side of the foil carrier has a silicone pressure sensitive adhesive which provides excellent adhesion to silicone-contaminated plastics and other low energy surfaces.

T411 thermally conductive tape consists of a high bond strength, pressure sensitive adhesive with an aluminum mesh carrier layer. The mesh carrier allows the tape to conform to curved surfaces of plastic molded IC packages, providing a high adhesive strength attachment for heat sinks. The high performance silicone-contaminated plastics and other low energy surfaces.
