Abstract
The present invention relates generally to thermally-conductive pastes for use with integrated circuits, and particularly, but not by way of limitation, to self-orienting microplates of graphite.
Claims15
A paste composition having anisotropic thermal transmission character comprising:
- graphitic platelets having a basal plane in a z-direction with a first length and a platelet plane having second and third lengths in an x- and a y-direction respectively, said second and third lengths larger than said first length, wherein said graphitic platelets are oriented such that the said basal planes of the said graphitic platelets are aligned in the direction of a desired heat flow;
- and
- a liquid.
