    摘要: Electrolytic capacitors may use a canister and a lid to confine an electrolyte and prevent the electrolyte from evaporating during use, and an improved seal between the canister and the lid may be achieved by increasing the surface area of the seal. For example, the surface area of the seal may be increased by changing the shape and/or thickness of the canister edge. For example, the surface area of the seal may be increased by changing the shape of an elastomer layer of the lid and/or adding an annular protuberance at the circumference of the lid. For example, the surface area of the seal may be changed by changing the process for forming the edge during the capacitor sealing.

    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.

    摘要: A capacitor manufacturing method is disclosed herein that includes a process for the isolation of electrode tabs attached to the capacitors' electrodes from other elements in the capacitor. An isolation patch or layer may be deposited over the tabs by a machine or a device after the tab is attached and before the electrodes are wound into a cylindrical internal element of a capacitor. The device may coat the tabs and surrounding regions with an isolating material. Electrode tabs may be provided with an isolating material pre-deposited at least in part over the tabs.
