Bondline 700 Twin Liner is an electrically insulating thermal adhesive tape used to mechanically secure and thermally link electronic components and FR4 PCBs to a heatsink. Bondline 700, made of acrylic, is pressure-sensitive. Its different thicknesses adapt to diverse surface textures, filling tiny air gaps between contact surfaces and lowering thermal resistance. Bondline 700 is designed for applications requiring effective thermal transfer, dielectric strength, and long-lasting adhesion.
Benefits
- Offers exceptional adhesion between a variety of substrates
- Brings an everlasting mechanical bond with high dielectric strength
- Easy to handle and apply
Features
- Electrically isolating acrylic thermal tape
- Conformability fills micro air voids between mating surfaces, decreasing thermal resistance
- Permits adequate heat exchange between the component and the cooling mechanism
Recommended Uses
Facilitates the fast and consistent attachment of power components, such as high and mid-power LED modules, directly to a heatsink.
