Polar Thermally Conductive Adhesive Tapes

Ceramic or metal packages
T405 thermal tape consists of a high bond strength, pressure-sensitive acrylic adhesive, loaded with aluminum oxide and coated onto a 0.050 mm (0.002 inch) aluminum foil carrier. The aluminum foil provides added thermal conductivity for applications where electrical isolation is not required.

T412 thermal tape consists of a high bond strength, pressure-sensitive acrylic adhesive, loaded with titanium diboride and applied to an expanded aluminum carrier. The combination of filler, expanded metal and embossed surface enhances both tape conformability and thermal performance.

How to order	Example P/N RT5635B000 _ _ (Last two digits tape option)
Ordering Code  Tape Option 05 T405 10 T410 11 T411 12 T412	Part Number RT5635B00000 Choose a tape option T405 (05), T410 (10), T411 (11) or T412 (12)  Then add the ordering code (05,10,11,12) to your part number (by replacing the last two digits.)  For Example: To order tape option T410 (10) with the part number  RT5635B00000 the completed part number to order would be RT5635B00010.
Plastic packages T410 tape consists of a high bond strength, pressure sensitive acrylic adhesive loaded with aluminum oxide and coated onto a 0.05 mm (0.002 inch) aluminum foil carrier. The other side of the foil carrier has a Silicon pressure sensitive adhesive which provides excellent adhesion to Silicon-contaminated plastics and other low energy surfaces. T411 tape consists of a high bond strength pressure-sensitive adhesive with an expanded 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 Silicon PSA allows adhesion to Silicon-contaminated plastics and other low energy surfaces.    Typical Properties T410 T411  Carrier Aluminum Foil Aluminum Mesh  Adhesive (to heat sink side) Acrylic Silicon  Color (to heat sink side) White Clear (Silver)  Adhesive (onto component side) Silicon Silicon  Color (to component side) Clear (Silver) Clear (Silver)  Thickness, mm (in.) 0.18 (0.007) 0.28 (0.011)  Thermal Impedance @<1 psi, 1.1 1.0  oc-in2/W (oc-cm2/W) (7.1) (6.5)  Operating Temperature  Range, oc - 50 to +150 - 50 to +150  Voltage Breakdown, Vac N/A N/A  Volume Resistivity, ohm-cm N/A N/A  Lap Shear Adhesion, psi (MPa) 60 (0.414) 14 (0.094)  Die Shear Adhesion, psi (MPa)     Steel/FR4 25oc  170 (1.172) 80 (0.552) Steel/FR4 125oc 40 (0.276) 20 (0.138)
