Abstract: front page image
(EN)A thermally conductive paste including a thermosetting resin and a thermally conductive filler and having a wet spreading area ratio of at least 90%. When the average particle diameter D50 of the thermally conductive filler is D, the viscosity, at a room temperature of 25°C, of the thermally conductive paste excluding the thermally conductive filler is η, and the degree of sedimentation of the thermally conductive filler in the thermally conductive paste is S = D2/η, S is 8 [10-12·m3·s/kg] – 900 [10-12·m3·s/kg].
(FR)L'invention concerne une pâte thermoconductrice comprenant une résine thermodurcissable et une charge thermoconductrice et ayant un rapport de surface d'étalement humide d'au moins 90 %. Lorsque le diamètre moyen de particule D50 de la charge thermoconductrice est D, la viscosité, à une température ambiante de 25 °C, de la pâte thermoconductrice à l'exclusion de la charge thermoconductrice est η, et le degré de sédimentation de la charge thermoconductrice dans la pâte thermoconductrice est S = D2/η, S est 8 [10-12·m3·s/kg] – 900 [10-12·m3·s/kg].
(JA)本発明の熱伝導性ペーストは、熱硬化性樹脂と熱伝導性フィラーとを含むものであり、濡れ広がり面積の割合が90%以上であり、熱伝導性フィラーの平均粒径D50をDとし、熱伝導性フィラーを除いた当該熱伝導性ペーストの、室温25℃における粘度をηとし、当該熱伝導性ペースト中における熱伝導性フィラーの沈降度合いを、S=D/ηとしたとき、Sが8[10-12・m・s/kg]以上900[10-12・m・s/kg]以下である。
