Interface Material / Double Sided Tape
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.

Uses a 0.001 inch (0.03 mm) Kapton MTTM 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.
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.

T412 for ceramic or metal packages
T410R / T411 for plastic packages
Uses an expanded foil carrier coated on both sides with
high-bond strength, pressure 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 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 PSA allows adhesion to
silicone-contaminated plastics and other low energy surfaces.
