摘要： A capacitor manufacturing method described herein includes a process for the isolation of edges of electrode foils in an electrolytic capacitor after slitting the electrode foils from a mother foil. For example, a coating process may be incorporated into the capacitor manufacturing so that the edges of the electrode foils may undergo isolation with a deposition of a layer of epoxy or resin. A manufacturing machine that incorporates a resin coating process may be positioned in the manufacturing line, such that the edges of the slit electrode foils undergo a deposition of a coating of an electrical isolator, such as a polymer, an epoxy, a resin, a ceramic, and/or an oxide layer. As another example, a combined foil with interleaving conducting bands and isolating strips may also be used to form the electrode foils with isolated edges.
