摘要

本文对新型热界面材料(TIMs')的电学性能进行了初步研究。所研究的TIMs是基于银片和银纳米颗粒(纳米银)的混合物，银含量高(重量超过90%)。这些材料经过固化和烧结后，形成了具有良好电学和机械性能的大块、均匀的银层。这使得这些材料适合用于大功率电子器件，因为大块银的导热性和导电性都非常高(429 W·m-1·K-1)。使所研究的材料非常有价值的是烧结过程的相对低温(类型)。120 - 150°C)。

Investigation of electrical properties of contacts made of materials based on sintered nano-Ag particles

In this paper preliminary investigations of electrical properties of new Thermal Interface Materials (TIMs') are presented and discussed. Investigated TIMs are based on mixture of silver flakes and silver nano-particles (nano-Ag) with high content of silver (more than 90% weight). After curing and sintering of such materials, as a result, a bulk, homogenous silver layer with good electrical and mechanical properties is formed. This makes those materials suitable for high-power electronics since both thermal and electrical conductivity of the bulk silver is very high (429 W·m-1·K-1). What makes investigated materials very valuable is a relatively low temperature of sintering process (typ. 120-150°C).
