Bondline 310 is a thermally conductive, double-sided adhesive tape made from a thin polymer that is coated with thermal adhesive on both sides.
It is specifically designed to bond two surfaces that necessitate a robust, permanent connection, exceptional thermal conductivity, and reliable electrical insulation up to 65,000 volts.
Bondline 310 provides a high-performance thermal solution for affixing heat-generating electronic components to a heatsink, cold wall, or chassis.
Benefits
- Eliminating micro air voids present between mating surfaces decreases thermal resistance
- A remarkably thin bond line measuring 0.12 mm enhances thermal performance
- Exhibits high dielectric strength suitable for rigorous electronic applications
Features
- This is a double-sided thermal adhesive tape made from KAPTON polyimide film and silicone rubber
- It provides outstanding electrical insulation while ensuring effective thermal connectivity
- The pressure-sensitive application enhances the bond strength to its maximum after a period of 24 hours
Recommended Uses
Attaching PCBs and FR4 materials to a heatsink. This is essential for cooling components in power supplies or power converters. It is applicable in high-voltage breakdown scenarios.
