What Are The Key Factors Influencing Alumina Substrate Performance During Preparation?
In the rapidly developing electronics industry, alumina substrate has become an indispensable substrate for electronic components with its excellent insulation properties, chemical stability, high thermal conductivity and good high-frequency characteristics. It not only provides support for electronic components, but also plays a key role in heat dissipation and insulation. However, the preparation process of high quality alumina ceramic substrate is complex and fine. The key factors such as raw material formula, casting film thickness and sintering process parameters directly affect the thickness uniformity, appearance quality and surface roughness of the product, and then determine the overall performance of the product. In this article, the effects of three key additives, binder, plasticizer and dispersant, and their process control were discussed in order to provide reference for optimizing the preparation process of alumina ceramic substrate.
