Customer ServiceDesign of High-Voltage Film Capacitors Film capacitors are manufactured in the form of a winding using a capacitor winding machine, or in the form of a stack of dielectric films.

Mold compounds can be used to encapsulate a range of electronic packages, including capacitors, transistors, central processing units, and memory devices. In basic terms, the process can be considered in two stages. First, the components to be encapsulated are transferred into mold cavities.
Different technologies are used in high-voltage capacitor manufacturing process, and at all stages of this process polymeric films must be used, along with an encapsulating material, which can be either liquid, solid or gaseous. These materials play major roles in the lifespan and reliability of components.
The three key dielectric properties needed when choosing a good film material for a capacitor are the dielectric constant or the relative permittivity, the dissipation factor and the breakdown strength .
The first step in building a metallized film capacitor is physical vapor deposition under vacuum of a very thin layer (10 to 100 nm) of metal, such as aluminum, zinc or zinc–aluminum, on one side (evaporated to the surface) of a roll of polymer film . Sometimes, small amounts of other alloy metals are added to prevent corrosion.
The use of certain gases, oils and resins in capacitors increases the emission of greenhouse gases into the atmosphere, as well as the risk of explosion due to the exposure of agents to oils during production. The desire to reduce carbon emissions has led to the production of capacitors and high-voltage equipment meeting environmental regulations.
