一、引言一个电子器件的设计最主要的内容应包括电参数设计、结构设计和热耗散设计三部份。作为电子器件所用的介质材料也必须保证这三方面设计的要求。即应具有良好的介电性能、机械性能和合适的热性能。 I. INTRODUCTION The main content of an electronic device design should include three parts of electrical parameter design, structural design and heat dissipation design. As a dielectric material used in electronic devices must also ensure that the design requirements of these three areas. That should have good dielectric properties, mechanical properties and appropriate thermal properties.
