Heat Sink Compound Dow Corning 340

Product Details

The Heat Sink Compound Dow Corning 340 has a Non-flowing thermal interface material which increases reliability, MIL-DTL-47113 compliant.

Description

Dow Corning® brand thermally conductive compounds are grease like silicone materials, heavily filled with heat-conductive metal oxides. This combination promotes high thermal conductivity, low bleed and hightemperature stability. The compounds are designed to maintain a positive heat sink seal to improve heat transfer from the electrical/electronic device to the heat sink or chassis, thereby increasing the overall efficiency of the device.

Importance of Thermal Management in Electronic Devices

Electronic devices are continually designed to deliver higher performance. Especially in the area of consumer electronics, there is also a continual trend towards smaller, more compact designs. In combination these factors typically mean that more heat is generated in the device. Thermal management of electronic devices is a primary concern of design engineers. A cooler device allows for more efficient operation and better reliability over the life of the device. As such, thermally conductive compounds play an integral role here.

Properties of Thermally Conductive Materials for Improved Heat Transfer

Thermally conductive materials act as a thermal “bridge” to remove heat from a heat source (device) to the ambient via a heat transfer media (i.e. heat sink). These materials have properties such as low thermal resistance, high thermal conductivity, and can achieve thin Bond Line ®™ Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow.
