Abstract

Рассмотрены основы технологии изготовления многослойных керамических конденсаторов, используемая на предприятии АО "НИИ "Гириконд". Описаны возможные способы формирования внутренних электродов многослойных конденсаторов. Разработана технология приготовления электродных паст для металлизации керамических листов при формировании внутренних электродов методом трафаретной печати. Изготовление паст проводилось с использованием элекродных порошков разного типа: порошки твердого раствора 70 Ag – 30 Pd, плакированные порошки состава 70 Ag – 30 Pd + BaTiO3. Исследовано влияние разных составов электродных паст на качество изготавливаемых конденсаторов. Разработанная технология опробована при изготовлении многослойных конденсаторов на основе различных керамических материалов. Доработаны составы металлизационных паст, используемых для металлизации контактных площадок керамических конденсаторов высоковольтной группы. Исследовано влияние состава стеклообразующей добавки на качество формирования контактных узлов. Предложен состав пасты, характеризующися наилучшими параметрами получаемых контактных площадок.

The fundamentals of the technology for manufacturing multilayer ceramic capacitors, used at the "NII "GIRICOND" JS Co, are considered. Possible methods of forming the internal electrodes of multilayer capacitors are described. A technology has been developed for the electrode pastes preparation for the metallization of "green" ceramic during the formation of internal electrodes by screen printing. Production of pastes performed using powders of different types: silver-palladium solid solutions of composition Ag70Pd30 and Ag70Pd30 coated BaTiO3. The influence of different compositions of electrode pastes on the quality of manufactured capacitors has been investigated. The developed technology has been tested in the manufacture of multilayer capacitors based on various ceramic materials. The compositions of pastes for termination of high-voltage multilayer ceramic capacitors have been improved. The influence of the glass-forming composition on the quality of the MLCC termination is investigated. The composition of the paste with the best parameters of MLCC termination is proposed.
