The process of making ceramic capacitors involves many steps. Ceramic powder is mixed with binder and solvents to create the slurry, this makes it easy to process the material. The slurry is poured onto a conveyor belt inside a drying oven, resulting in the dry ceramic tape. This is then cut into square pieces called sheets. The thickness of the sheet determines the voltage rating of the capacitor. The electrode ink is made from a metal powder that is mixed with solvents and ceramic material. The electrodes are now printed onto the ceramic sheets using a screen printing process. This is similar to a t-shirt printing process. After that, the sheets are stacked to create a multilayer structure. Pressure is applied to the stack to fuse all the separate layers, creating a monolithic structure. This is called a bar. The bar is cut into all the separate capacitors. The parts are now in what is called a ‘green’ state. The smaller the size, the more parts there are in a bar.
