Product Description

PCM45F is Honeywell's thermally conductive phase change pad. It is designed to minimize thermal resistance at interfaces and maintain extremely stable performance through reliability testing required for long product life applications. In addition to that it has excellent electrical properties and very high volume resistivity.
PCM45F has a Thermal conductivity of 2.0 - 2.5 (W/m·K) depending on the bondline thickness and is based on a robust polymer PCM structure that exhibits excellent wetting properties during typical operating temperature ranges, resulting in very low surface contact resistance. The proprietary material provides superior reliability and maintains low thermal impedance (0.09-0.12) , making it desirable for high-performance integrated circuit devices.

Technical Specifications

General Properties
Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
Thickness range 0.20 - 1.00 mm
Electrical Properties
Volume Resistivity
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.

Thermal Properties
Thermal Conductivity
Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.

Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
2.0 - 2.5 W/m.K
Thermal Impedance 0.09 - 0.12 °C·cm²/W

Additional Information

When choosing a printable paste it is important to understand the process parameters and limitations.

That's why we ask, when you contact us, to include  the following information:

  1. What is your print thickness?
  2. How long is your printing time and working window?
  3. What is your drying step after printing?
    • Temperature (Room temperature or something else?)
    • Time 
  4. Do you have any viscosity limitations in the printing process?
