Solid electrolytic capacitor article, solid electrolytic capacitor, lead frame and method for manufacturing solid electrolytic capacitor
Disclosed is a solid electrolytic capacitor article including a lead frame having at least a pair of an anode terminal and a cathode terminal, a capacitor element which is connected to the anode terminal and the cathode terminal, and a silicone resin layer that coats the anode terminal, the cathode terminal, and the exterior surface of the capacitor element connected thereto.
1. A method for manufacturing a solid electrolytic capacitor comprising:
a step of connecting a lead frame having at least a pair of an anode terminal and a cathode terminal, and a capacitor element,
a step of coating the anode terminal, the cathode terminal and an exterior surface of the capacitor element connected to the anode terminal and the cathode terminal with a silicone resin layer,
a step of performing resin sealing, with a resin that is different from the silicone resin, of a portion of the anode terminal and the cathode terminal that have been coated with the silicone resin layer, and the capacitor element connected to the terminals,
a step of removing the silicone resin layer from a portion of the anode terminal and the cathode terminal not sealed by the resin sealing, and
a step of forming a plating layer with a thickness greater than the silicone resin layer on the portion of the anode terminal and the cathode terminal from which the silicone resin layer has been removed.
2. The method for manufacturing a solid electrolytic capacitor according to claim 1 , further comprising, prior to the step of performing coating with the silicone resin layer, a step of dipping an integrated structure formed from the lead frame and the capacitor element in a solution containing a dissolved surfactant.
