Phase Change

Hi-Flow 565UT

Features & Benefits

  • Thermal impedance: 0.05°C-in2/W (@25 psi)
  • High thermal conductivity: 3.0 W/mK
  • Phase change softening temp 52°C
  • Natually tacky
  • Tabulated for ease of assembly

Description

Hi-Flow 565UT is a naturally tacky, thermally conductive phase change material which is supplied in an easy to use tabulated pad form. In the application the material undergoes a phase change softening, starting near 52°C.The phase change softening feature improves handling characteristics prior to a facilitated assembly. At application temperatures and pressures, Hi-Flow 565UT wets out the thermal interfaces resulting in a very low thermal impedance. The thermal performance of Hi-Flow 565UT is comparable to the best thermal greases. Hi-Flow 565UT is provided at a consistent thickness to ensure reliable performance. Hi-Flow 565UT can be applied in high volumes to the target surface via low pressure from a roller or manual application.

Typical Applications include

  • Processor lid to heat sink
  • Processor die to lid or heat sink
  • FBDIMM to heat spreader
