Ceramic capacitor manufacturing process
💥Silver Paste Spraying
👉Silver Paste Spraying is one of the methods for coating electrodes in ceramic, glass, mica and other inorganic dielectric capacitors. Its working principle is through spray paint, which uses 4 to 5 atmospheres of compressed air to spray silver paste on the surface of the medium covered with the template. The silver paste coated in this way is uniform and smooth.
💥Screen Printing of Silver Paste
👉Screen Printing of Silver Paste is one of the methods for coating silver electrodes such as ceramic capacitors, mica capacitors, glass and glass glaze capacitors. The pattern of the missing paste on the screen can be made by methods such as photolithography and film sticking. When printing, place the media under the screen, and then use a squeegee silver paste to print on the media. The advantages of this method are high efficiency, saving raw materials, and good consistency of electrode shape and size.
👉Silver Pastebrushing is one of the methods of coating the silver layer. It uses a silver-coated pen or other tools to apply silver paste to the surface of the medium that needs to be coated with silver. Silver coating machines include tube type and disc type.
👉Silver Pastepring is similar to stamping. The end of the “stamp” printed with silver is generally made of materials such as mud, foam, etc., which are easy to absorb silver paste and have a certain degree of flexibility.
💥Silver Electrode Firing
👉Silver Electrode Firing is the common name for burned silver electrode. The silver paste coated on the surface of ceramics, glass or mica must be fired. During this process, the silver paste reacts to form a continuous, dense and firmly bonded metal silver layer with the surface of ceramics. There are two types of silver burning equipment: tunnel furnace and box furnace. Generally, the burning temperature of silver is +500~+900℃, but the burning temperature of mica flakes must be below +600℃ (because mica will lose crystal water above +600℃, which will deteriorate the performance).
👉Silver Ink is a paste for making silver electrodes. It is formulated with silver or its compounds, fluxes, adhesives and diluents. According to the existence form of silver, it can be divided into oxidized silver paste, carbonate silver paste, and molecular silver paste. According to the burning temperature, it can be divided into high temperature silver paste and low temperature silver paste. According to the coating method, it is divided into printing silver paste, spraying silver paste and so on.
