Forming method for sheath of cylindrical solid electrolytic capacitor

Abstract

Abstract PURPOSE:To efficiently form a sheath by dropping and filling synthetic resin liquid having predetermined viscosity between a cathode electrode and an anode electrode while rotating a capacitor assembly at an anode lead as a rotating axis. CONSTITUTION:A capacitor assembly 10 is supplied by a dispenser nozzle 11 to an anode terminal 7 while rotating it at an anode lead 6 as a center, and resin liquid 12 is adhered in a crest state. The nozzle 11 is directed toward a cathode terminal 5, and the liquid 12 is supplied to the terminal 5 in a crest state. It is allowed to stand for a predetermined period of time while continuing the rotation of the assembly 10. The liquid 12 is cured by irradiating it with an ultraviolet ray, thereby forming a sheath 8 made of ultraviolet curable resin. Thus, the sheath 8 is efficiently formed.
