MLCC palladium silver internal electrode pasteIt is mainly composed of palladium silver powder, organic carrier, and inorganic additives The experiment shows that the palladium content in palladium silver powder determines the firing temperature and cost price of the slurry; The function of organic carriers is to provide certain rheological properties of the slurry to meet the process requirements of MLCC screen printing. The degree of thixotropy of organic carriers directly affects the quality of the slurry screen printing graphics; The function of inorganic additives is to suppress the rapid shrinkage of the slurry during the firing process. Choosing different inorganic additives can adjust the matching of the firing shrinkage rate between the electrode layer and the dielectric layer formed by the slurry during the firing process, avoiding quality problems such as electrode cracking caused by matching problems in MLCC products
A silver palladium powder with a palladium silver ratio of 5/95 was prepared, and a mixed system of ethyl cellulose and alkyd resin was used as the organic carrier. A small amount of glass powder was added to obtain a high-performance silver palladium powderInternal electrode silver palladium slurryCan be used on piezoelectric ceramic speakers
This slurry is suitable for external labeling and outer packaging of circuits and resistors, and can be used for substrates such as glass, ceramics, stainless steel, aluminum alloys, etc
The paste is suitable for marking thick film circuit and outside package, glass, ceramic, metal, etc.
