3M™ Thermally Conductive Heat Spreading Tape 9876B-05 • 9876B-08 • 9876-10 • 9876-15
3M™ Thermally Conductive Heat Spreading Tape (TCoHST) 9876 is designed to provide excellent heat spreading performance on plane direction for stimulation of quick heat dissipation with a preferential heat-transfer path between heat-generating components and designated cooling devices (e.g., heat sink, fans, heat pipes and metal frame). 3M tapes 9876B-05 and 9876B-08 have a black top coated polymeric layer for color matching appearance. 3M tapes 9876-10 and 9876-15 have a copper color top side appearance.
Generally, heat spreaders conduct to distribute thermal energy from a heat-generating component to another location where the heat can be removed through a heat dissipation mechanism. Focused on increasing the X-Y direction thermal conductivity to enhance heat spreading, 3M tape 9876 is designated to solve the limitation of existing products.
The multi layered metal heat spreader provides following benefits
1. Preferential X-Y thermal conductivity – 3M tape 9876 promotes heat spreading on plane direction and minimizes effective total heat conduction on Z-axis.
2. Good adhesion performance – The 3M tape 9876/9876B uses a high performance acrylic PSA for excellent adhesion to many substrates.
3. High thermal conductivity in X-Y direction – The thermal conductivity is proportionate to the effective thermal heat spreading performance of the metal foil layer(s).
4. Flexibility – The pressure sensitive adhesive layers provide flexibility to the laminate and improves the workability.
5. Excellent electrical insulation – 3M tape 9876 has a thin, permanent polymeric cover film that provides for electrical isolation to the heat spreading metal top surface, provides for easier handling of the 3M tape 9876 and reduces product deformation during handling. 3M tape 9876B-08 has a black ink coated polymeric film to provide excellent electrical insulation and handling.
6. No debris, No need for sealing, 3M tape 9876 can be die cut with no loose debris or potential for burrs or slivers.
This product does not contain any banned chemical, heavy metal, halogen compounds or other restricted materials.
There are four thicknesses available. 3M tape 9876-10 is 100µm, 3M tape 9876-15 is 150µm, 9876B-05 is 50µm and 3M tape 9876B-08 is 80µm thickness.

Application Techniques
• 3M tape 9876 should be applied in a manner to minimize wrinkles, bubbles and folds as to maximize the heat
spreading performance of the product along the desired XY plane.
• Bonding strength is dependent upon the amount of adhesive to surface contact developed. Firm application pressure
helps to develop better adhesive contact and improve bonding strength.
• To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Typical surface cleaning
solvents are isopropyl alcohol and water (rubbing alcohol) or heptane. Note: Be sure to follow manufacturer’s safety
precautions and directions for use when using solvents.
• Ideal tape application temperature range is 21°C to 38°C (70°F to 100°F). Initial tape application to surfaces at
temperatures below 10°C (50°F) is not recommended because the adhesive becomes too firm to adhere readily.
However, once properly applied, low temperature holding is generally satisfactory.
