Thermal Adhesives

Thermal adhesives are a type of adhesive commonly used to attach a heatsink to electronic components. The glue is typically a two part epoxy resin which cures to form a strong bond. They are thermally conductive and usually electrically insulating, helping to dissipate heat from the device to prevent overheating or a breakdown.

The main function of a thermal adhesive is to ensure there is no air space between which would act as a thermal insulator. It fills in the microscopic imperfections on the heatsink and device.

There are a variety of thermal compound adhesives available that are ideal for eliminating the air gap under a heat sink. The most common types of thermally conductive adhesives are:

  • Thermal paste
  • Thermal glue
  • Thermal adhesive tape
  • Thermal Grease
  • Thermal Gap Pads

Applications

Thermal adhesives are used in a variety of industries and applications such as:

  • Heat sink bonding
  • Potting/encapsulating sensors
  • BGA die heat spreader interface
  • Chip scale packages
  • Power semiconductors
