THERMFLOW Phase-Change Thermal Interface Pads
Phase Change Thermal Interface
THERMFLOW™ materials are thermally
enhanced polymers designed to
minimize the thermal resistance
between power dissipating electronic
components and their associated heat
sinks. This low thermal resistance path
maximizes heat sink performance and
improves the reliability of microprocessors,
memory modules, DC/DC converters
and power modules.
The key feature of THERMFLOW materials is their phase-change characteristic. At room temperature, THERMFLOW materials are solid and easy to handle. This allows them to be consistently and cleanly applied as dry pads to a heat sink or component surface. THERMFLOW material softens as it reaches component operating temperatures. With light clamping pressure it will readily conform to both mating surfaces, similar to thermal grease. This ability to completely fill interfacial air gaps and voids typical of component packages and heat sinks allows THERMFLOW pads to outperform nonflowing elastomeric or graphite-based thermal pads and achieve performance comparable to thermal grease.
THERMFLOW materials are electrically non-conductive. However, since metal-to-metal contact is possible after the material undergoes phase-change in a typical heat sink assembly, THERMFLOW pads should not be used as electrical insulators.
