WE-PCM: Thermal Phase Changing Material

Würth Elektronik's WE-PCM is designed to provide a seamless thermal interface between a component and a cooling assembly

Image of Würth Elektronik WE-PCM: Thermal Phase Changing Material Wurth Elektronik's WE-PCM series is designed as an alternative to the use of thermal pastes and greases between high-performance components, such as processors or power components and cooling assemblies. This material changes from a solid to liquid at a specific temperature providing a complete wet-out of the interface without any spills or overflow. The phase changing material itself is composed of three main components:

  • Release PET film: The WE-PCM is protected by two PET films on top and bottom to protect the material from foreign particles. The PET films must be removed before placing the material.
  • Phase changing material: Main component of the product.
  • Polyimide film: This component is present in some of the standard parts to provide electrical insulation while maintaining its thermally conductive capabilities.

The WE-PCM is designed to provide a seamless thermal interface between a component and a cooling assembly. A benefit of the complete wet-out of the contact surfaces as well as the thinness is that the thermal resistance provided by the material is very low compared to other interface solutions.
