Abstract
An article including a first release liner with a first release surface, a second release liner with a second release surface, and a layer of a thermally conductive grease between the first and the second release surfaces. The thermally conductive grease includes a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D50) particle size which differs from the other distributions by at least a factor of 5.

An article comprising:
- a first release liner comprising a first release surface;
- a second release liner comprising a second release surface;
- and
- a layer of a thermally conductive grease between the first and the second release surfaces, wherein the thermally conductive grease comprises a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D50) particle size which differs from the other distributions by at least a factor of 5.
An article comprising:
- a first release liner comprising a first release surface;
- a second release liner comprising a second release surface;
- and
- a layer of a thermally conductive grease between the first and the second release surfaces, wherein the thermally conductive grease is substantially PCM-free, and wherein at least one of the first and second release surfaces comprises a fluorocarbon material, a silicone material, a fluoro-silicone material, an acrylic, or a combination thereof.
An electronic assembly comprising:
- a substrate comprising at least one of an electronic component, a thermal dissipative member and a thermal distributing member;
- a layer of a thermally conductive grease on the substrate, wherein the thermally conductive grease comprises a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D50) particle size which differs from the other distributions by at least a factor of 5;
- and
- a release liner with a release surface on the layer of the thermally conductive grease.
A method for making an electronic device, comprising:
- providing a laminate comprising
- a first release liner comprising a first release surface, and
- a second release liner comprising a second release surface, and
- a layer of a thermally conductive grease between the first and the second release surfaces, wherein the thermally conductive grease comprises a mixture of at least three distributions of thermally conductive particles, each of the at least three distributions of thermally conductive particles having an average (D50) particle size which differs from the other distributions by at least a factor of 5;
- removing the first release liner to at least partially expose the layer of the thermally conductive grease;
- and
- applying the layer of the thermally conductive grease to a substrate comprising one of an electronic component, a thermal dissipative member or a thermal distributing member.
