Powered surface mount technology (SMT), the whole small -shaped , high-frequency continuous development , with a low equivalent series resistance (ESR), high Q value chip RF / microwave MLCC and chip RF / microwave film capacitors, because of its excellent RF power characteristics highly favor of mobile communications, radio and television , and satellite communications transmitter base station . And in a mobile phone, wireless local area network (W-LAN) and other wireless communication and information terminal product to be widely applied. The miniaturized chip microwave single-layer ceramic capacitors (SLC) show good prospects for the development . SLC is widely used in the microwave monolithic integrated circuit ( MMIC ) . : Oscillator , power amplifier , mixer , etc. , can achieve filtering , DC blocking , impedance matching , RF bypass coplanar waveguide functions . Miniaturization trends in order to adapt to the small volume of products , the localization requirements of the company according to the market demand and capacitor , issued a research and development project of the single-layer ceramic capacitors . Multilayer ceramic capacitor production , combined with sputtering , electroplating , lithography principle , discusses the single-layer ceramic capacitor from the design stage to the products put into use stage process . First introduced single-layer ceramic capacitors dynamics and development trends in the domestic and international research , followed by the introduction of the basic principles of electrode preparation , and capacitor design ideas are briefly described , Finally, according to the preparation process of the ceramic substrate and electrode problems and key technologies were discussed . This study the single-layer ceramic capacitor ceramic substrate to be processed based on the dielectric film casting method process and rolling membrane process design , the electrode is made ??of magnetron sputtering and electroplating molding . The test results show that the single-layer ceramic capacitor paper developed indicators meet the design requirements , design, process and test platform to meet production needs .
