In electronic devices, heat removal is an important consideration of any device designer. Thermally conductive, high-temperature polyimide composites are disclosed herein which are generally useful as a dielectric layer in an electronic device, or a precursor metal-laminate, where the dielectric is layered on one side (or on both sides) with a metal. The polyimide composites of the present invention contain dispersed therein thermally conductive filler particles at a weight percent between 40 and 85 % weight percent. These film composites have good dielectric strength, good thermal conductivity, and optionally good adhesivity.
在电子设备中,散热是任何设备设计者都要考虑的重要问题。本发明公开了导热性高温聚
酰亚胺复合材料,它通常可用作电子设备中的电介质层或
金属层压板的前驱体,其中电介质在一侧(或两侧)与
金属分层。本发明的聚
酰亚胺复合材料中分散有重量百分比在 40% 至 85% 之间的导热填料颗粒。这些薄膜复合材料具有良好的介电强度、导热性和可选的粘合性。
