Electrical component for surface-mounting, and method for its fabrication

摘要

The electrical component is, in particular, a chip capacitor in the form of a foil capacitor having metallised foils or - preferably, - of a tantalum capacitor having a solid electrolyte, with a casing produced from fluidised-bed coating powder in a fluidised-bed coating process, and with frontal front-contact (butting-contact) layers. In order to preclude soldering problems owing to the camber (crown) of the casing obtained in conventional fluidised-bed coating processes, the coating is pressed flat on at least one side to produce a planar face which runs parallel to the component axis, the front-contact layers which project axially beyond the casing terminating at said planar face or slightly projecting beyond it. Said pressing flat can be effected, after the fluidised-bed coating process, between heated cheek plates, after the fluidised-bed coating powder has been gelled on by a heat treatment.
