Compressible and Phase-Change Interface Materials

COOL-GELFILM™ is another innovation that is a thermal interface gel in the film format for ease of applications for critical thermal interfacing requiring high reliability without heat of provision of clips or pressure. This compressible and comformable thermal interface materials does not phase change but is pressure sensitive to provide immediate thermal interface performance.

Cool Gelfilm Pad

COOL-GAPFILL™ is yet another enhanced thermal gap-filling materials that provides extreme thermal conductivity and thus unparalleled thermal interface resistance for board level multiple component thermal management. It is designed to provide conformability and compressibility to bridge the thermal gap of large boards and sensitive components. It is non-phase change and non-silicone and thus will not contaminate components. While one side remain dry but conformable for easy removal while the heat-sinking or heat-spreading side is pressure sensitive to provide the optimum thermal interface with low thermal impedance and thermal resistance.

Phase-Change Thermal Interface Pads, Comressible Phase-Change Thermal Interface Materials, Compressible and Conformal Thermal Interface Gap Pads, and Pressure Sensitive Thermal Pads

AIT pioneered the use of phase-change materials for use as thermal interface adhesive materials for thermal management in the early 1990's. These phase change materials used as specialty adhesives found acceptance in both military and commercial electronics over the last 15 years. AIT has patented the use of "compressible phase-change" thermal interface materials and "in-situ curing" thermal interface adhesive materials with one of the lowest thermal interface resistance. This new class of compressible phase change gap-filling materials enable the filling of large gaps between heat-spreader and the heat generating components that may have substantial differential heights. The following tables represent some of these innovative gap-filling phase change interface materials and their solutions and advantages:

  • Compressible phase-change interface materials that compensates for large area and extreme height tolerances and gaps.
  • In-situ curing thermal interface adhesive materials that provides up to 300 psi as applied and cure to over 600-1200 psi over time at operating temperatures of the device.
  • Available as electrically conductive or electrically insulating thermal adhesives, thermal greases, thermal gels and thermal pads.
  • Available as dry, single-sided or double-sided pressure sensitive tacky thermal interface pads and thermal adhesives film tapes.
  • Available in preforms of thermal phase change material pads and thermal adhesive films and tapes.
  • Phase-change thermal interface pad materials that flow at 55°C, 90°C, 130°C, and 180°C respectively.
  • Phase-change materials of all thickness with outstanding thermal conductivitity and low thermal interface resistance to help cool and manage power devices as adhesives, greases, gels and gap filling compressible thermal pads.
