Main features

0.09 - 0.12 Thermal Impedance
2.0 - 2.5 Thermal Conductivity
High volume resistivity

Product Description

PCM45F-SP is Honeywell's thermally conductive phase change paste, which is available in Stencil printable form. 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-SP 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.

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.	2.2
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.	8.2x10¹⁴ Ohms⋅cm
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
