Abstract:
A thermally conductive paste of the present invention includes a thermosetting resin and a thermally conductive filler, a ratio of a wet spreading area is 90% or more, and when an average particle size D 50  of the thermally conductive filler is referred to as D, a viscosity of the thermally conductive paste excluding the thermally conductive filler at room temperature 25° C. is referred to as η, and a degree of sedimentation of the thermally conductive filler in the thermally conductive paste is referred to as S=D 2 /η, S is 8 [10 −12 ·m 3 ·s/kg] or more and 900 [10 −12 ·m 3 ·s/kg] or less.

Claim (Index 1):
A thermally conductive paste comprising:\n a thermosetting resin; and a thermally conductive filler, wherein a ratio of a wet spreading area calculated by the following measurement method is 90% or more, and wherein when an average particle size D 50  of the thermally conductive filler is referred to as D, a viscosity of the thermally conductive paste excluding the thermally conductive filler at room temperature 25\u00b0 C. is referred to as \u03b7, and a degree of sedimentation of the thermally conductive filler in the thermally conductive paste is referred to as S=D 2 /\u03b7, S is 8.0 [10 \u221212 \u00b7m 3 \u00b7s/kg] or more and 802.8 [10 \u221212 \u00b7m 3 \u00b7s/kg] or less; (Measurement Method of Wet Spreading Area) wherein the measurement method of wet spreading area is as follows: the thermally conductive paste is applied to a surface of a lead frame using a 5-cc syringe from one end to the other along two diagonals line connecting diagonal 2 mm\u00d72 mm square so as to that the two application lines intersect; next, the resultant is statically left at room temperature 25\u00b0 C. for 8 hours; next, a 2 mm\u00d72 mm silicon bare chip having a thickness 0.525 mm is mounted on the lead frame through the thermally conductive paste under a load of 50 g and 50 ms, and thereafter the ratio of the wet spreading area of the thermally conductive paste to the surface of the silicon bare chip is calculated.
