A thermal interface material assembly comprising a thermal interface material, a first liner, a first coating directly on the thermal interface material between a first surface of the thermal interface material and an inner surface of the first liner, a second liner, and a second coating directly on the thermal interface material between a second surface of the thermal interface material and an inner surface of the second liner, wherein the thermal interface material comprises a first silicone and thermally-conductive filler, the first coating comprises a second silicone, and the second coating comprises a third silicone, whereby the first coating is configured such that at least a portion of the first coating will remain along the first surface of the thermal interface material after removal of the first liner from the thermal interface material assembly to thereby decrease a surface tack of the first surface of the thermal interface material, and whereby the second coating is configured such that at least a portion of the second coating will remain along the second surface of the thermal interface material after removal of the second liner from the thermal interface material assembly to thereby increase a surface tack of the second surface of the thermal interface material.
A thermal interface material assembly comprising a thermal interface material having a first surface and a second surface, a first coating directly on the first surface of the thermal interface material, a second coating directly on the second surface of the thermal interface material, the thermal interface material comprising a first silicone and thermally-conductive filler, the first coating comprising a second silicone, the second coating comprising a third silicone, whereby the first coating decreases the surface tack of the first surface of the thermal interface material, and whereby the second coating increases the surface tack of the second surface of the thermal interface material.
A method of controllably changing surface tack of a thermal interface material, the method of comprising:
- applying a first coating along an inner surface of a first liner;
- applying a thermal interface material along the first liner such that the first coating is directly on the thermal interface material between a first surface of the thermal interface material and the inner surface of the first liner;
- applying a second coating along an inner surface of a second liner;
- and
- applying the second liner over a second surface of the thermal interface material such that the second coating is directly on the thermal interface material between the second surface of the thermal interface material and the inner surface of the second liner;
- wherein the thermal interface material comprises a first silicone and thermally-conductive filler, the first coating comprises a second silicone, the second coating comprises a third silicone,
- whereby the first coating is configured such that at least a portion of the first coating will remain along the first surface of the thermal interface material after removal of the first liner from the thermal interface material to thereby decrease a surface tack of the first surface of the thermal interface material, and whereby the second coating is configured such that at least a portion of the second coating will remain along the second surface of the thermal interface material after removal of the second liner from the thermal interface material assembly to thereby increase a surface tack of the second surface of the thermal interface material.
