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
