When you need to bond a heat sink, spreader, or cooling element to a PCB without mechanical fasteners or liquid adhesives, thermally conductive tape offers a clean, repeatable solution. NEDC converts Bond-Ply and other thermally conductive tapes into custom shapes — in any volume, to your exact tolerances.
At NEDC, double-sided tapes are a common material we deal with. Essentially a double-sided tape is material that has adhesive on both sides. This is with a carrier in the middle of two adhesive coatings of material. In some cases, thermal conductivity is a requirement on these materials. Bond-Ply is a thermally Conductive tape that is a commonly used solution for those type applications. Bond-Ply has a competitive price point and lots of options of availability. These thermal interface pads are widely used across the industry for different mounting applications.
Properties of Bond-Ply Thermally Conductive Tapes
Bond-Ply is a one part tape that is available in roll form. They are electrically isolating, and a clean solution to use. These thermally conductive tapes are easy to die-cut, and have applications of mounting heat-sinks, and heat spreaders onto different heat-generating devices. Bonding with Bond-Ply materials focuses on how well the material wet-outs onto surfaces, and surface preparation. Naturally, with any thermal interface material, pressure and wet-out are two of the main concerns when discussing thermal performance. As demonstrated in the graph below, Bony-Ply has excellent thermal performance.
Applications Utilizing Bond-Ply Thermally Conductive Tape
-Mounting Heat Sinks onto BGA graphics processors, or drive processors
-Heat spreader onto motor control PCB
-Mounting LED assemblies to heat sinks

Thermally Conductive Tape vs. Thermal Pad vs. Thermal Paste
How Does Thermally Conductive Tape Compare to Thermal Pads and Paste? Thermally conductive tape sits between thermal pads and liquid adhesives in the design hierarchy. Unlike pads, tape has adhesive on both sides — eliminating the need for clips, screws, or curing. Unlike thermal paste, tape provides structural bond strength and consistent bond-line thickness without pump-out or dry-out over time. For applications where vibration, repeated thermal cycling, or production speed are concerns, tape is often the right choice. See how all three compare in our thermal interface materials guide.
