Q-Pad® 3

Glass-reinforced grease replacement thermal interface

Image of Bergquist's Q-Pad® 3 Bergquist's Q-Pad® 3 eliminates problems associated with thermal grease such as contamination of electronic assemblies and reflow solder baths. The Q-Pad 3 may be installed prior to soldering and cleaning without worry. When clamped between two surfaces, the elastomer conforms to surface textures thereby creating an air-free interface between heat-generating components and heat sinks.


  • Thermal impedance: 0.35°C-in2/W (@ 50 psi)
  • Eliminates processing constraints typically associated with grease
  • Conforms to surface textures
  • Easy handling
  • May be installed prior to soldering and cleaning without worry


  • Between a transistor and a heat sink
  • Between two large surfaces such as an L-bracket and the chassis of an assembly
  • Between a heat sink and a chassis
  • Under electrically isolated power modules or devices such as resistors, transformers, and solid state relays
  • U.L. file number E59150
