Metallic packaging structurized chip-type tantalum capacitor and packaging method thereof

Abstract

The invention relates to a metallic packaging structurized chip-type tantalum capacitor and a packaging method thereof. With the adoption of a metallic packaging structure, a layer of bonding conductive glue wraps outside a tantalum chip, and then a layer of metal shell wraps outside the bonding conductive glue; and meanwhile, one head of the tantalum chip is connected with a tantalum filament, and the tantalum filament is led out of the metal shell through a tantalum filament leading-out line to form the metallic packaging structurized chip-type tantalum capacitor. The tantalum filament and the tantalum filament leading-out line are connected together by welding, a welding point of the tantalum filament and the tantalum filament leading-out line is arranged on the inner surface of the metal shell, an insulation block sleeves outside the welding point of the tantalum filament and the tantalum filament leading-out line, the bonding conductive glue wraps between the insulation block and the tantalum chip and also wraps outside the insulation block, and thus, the spaces among the tantalum chip, the tantalum filament, the tantalum filament leading-out line and the shell are relatively fixed.
