“Graphite-PAD” high thermal conductivity in z-direction
Graphite-PAD is a thermal interface material (TIM) that compatibly obtained excellent thermal conductivity in thickness direction (Z-axis direction) and high flexibility (deformable with a low load). The properties are greater than that of existing TIMs. The product is created by filling PGS Graphite Sheet into silicon resin.
● High thermal conductivity : 13 W/m ∙ K
● Excellent compressibility : 50 % (t=2 mm, Pressure 300 kPa)
● Thermal resistance: fi t into uneven parts and provide excellent thermal resistance with a low load
● High reliability : correspond to −40 to 150 °C and maintains long-term reliability
● Thickness range : 0.5/1.0/1.5/2.0/2.5/3.0 mm
● RoHS compliant
Cooling of heat generating components, such as electronic devices, semiconductor memory device, etc.
● General-purpose inverter, medical equipment, and DSC
● Car-mounted camera, motor control unit, automotive lighting (LED), car navigation,
luminous source of laser HUD
● Base station, IGBT module
● Graphite-PAD (EYGT ✽✽✽✽✽✽✽✽ )
