Capacitor Working Principle
A capacitor consists of two conductive plates separated by a dielectric. The opposing surfaces of the two conductive plates can hold equal and opposite charges and create an electric field. The dielectric of Saifu's capacitors is polypropylene film, and the conductive plate is metallized layers (zinc-aluminum or pure aluminum layers) by physical vapor deposition (vacuum evaporation). For ease of use, two or more layers of metallized film with lengths of several meters to thousands of meters are wound into capacitor elements. Saifu's capacitors for sale are composed of single to hundreds of capacitor elements according to capacitor specifications.

Multilayer Ceramic Capacitor Manufacturing Process
The manufacturing process of multilayer ceramic capacitors (MLCCs) generally involves the following steps:

Mixing: The raw materials, which typically include ceramic powders, metal oxides, and binders, are mixed together in a ball mill to form a homogeneous slurry.

Forming: The slurry is then poured into a mold or cast onto a tape, which is then cut into individual chips of the desired size and shape.

Drying: The formed chips are dried in a drying oven to remove any remaining moisture from the slurry.

Firing: The dried chips are then fired in a high-temperature furnace to sinter the ceramic and metal oxide powders into a solid, crystalline structure. This process also burns off the organic binders, leaving behind a pure ceramic material.

Electrode deposition: Once the chips have been fired, metal electrodes are deposited onto the ceramic surface using a variety of techniques, such as screen printing or sputtering.

Stacking: The chips are then stacked on top of each other, with each layer separated by a thin layer of insulating material, typically made of ceramic or glass.
