Method for manufacturing a solid electrolytic capacitor

摘要

Cathode and anode sides of a plurality of solid electrolytic capacitors are connected by simultaneous electric welding. The welding step is effected to connect an anode lead of a lead frame to the anode electrode of a capacitor body and simultaneously connect a cathode lead of the lead frame to the cathode conductor layer of an adjacent capacitor body. The welding electrode for the cathode lead exerts moderate force to the capacitor bodies using a spring function of the capacitor lead. The simultaneous welding for the adjacent capacitor bodies and the moderate force prevent electrical and mechanical damages of the insulator layer of the solid electrolytic capacitors during the welding.
