The thermally conductive, double-sided tape consists of a superior bond strength, pressure-sensitive acrylic adhesive loaded with titanium diboride and applied to an expanded aluminum carrier. The tape is embossed with an innovative pattern for maximum conformability and minimal air pockets and offers excellent thermal, mechanical, environmental, and chemical properties. Our thermally conductive double-sided tape can bond heat sinks and thermal plates to components without the use of clips, screws, other mechanical fasteners, or additional thermal compounds and can be removed after the application without damage to the component.
This tape requires pressure to bond. At room temperature, we recommend holding components together with a minimum of 10 psi for 15 seconds, or preferably 30 psi for 5 seconds.
Before application, ensure that bonding surfaces are free from oil, dust, or any contamination that may affect bonding. Wearing gloves, wipe surfaces with a clean, lint-free cloth dampened with industrial solvents such as acetone or isopropyl alcohol. When cutting tape to size, we recommend cutting it slightly smaller than the area to be taped.
Apply the tape to the center of the heat sink bonding area and smooth over the entire surface with a hand or roller. More pressure produces better wetting out of the adhesive to the contact surfaces. A twisting motion during assembly of the two bonding surfaces will typically improve wetting. Note that typically 70% of the ultimate adhesive bond strength is achieved with initial application, and 80-90% is reached within 15 minutes. Ultimate adhesive strength is achieved within 36 hours; however, the next handling step can typically occur immediately following the initial application.
To remove, carefully insert a thin, short blade into the bond line at a corner between the components. Remove the blade and insert a spatula into the wedge. Slowly twist the spatula blade so that it exerts a slight upward pressure. As the two surfaces start to separate, move the spatula blade deeper into the bond line and continue the twisting motion and upward force. After the two components are separated, the tape can be removed and discarded.
If adhesive remains on the surfaces, it should be removed. Adhesive is best removed by wiping with a clean, lint-free cloth dampened with solvent. Use sufficient solvent to remove all adhesive. Parts must be free of solvent before applying more adhesive.
