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 pasteThermal glueThermal adhesive tapeThermal GreaseThermal Gap PadsApplicationsThermal adhesives are used in a variety of industries and applications such as:Heat sink bondingPotting/encapsulating sensorsBGA die heat spreader interfaceChip scale packagesPower semiconductors
