Method and a device for the production of electrical components, in particular laminated capacitors

Claim 1

Apparatus for producing electrical components which have at least one metal coating and at least one polymer coating carried one on top of another on a carrier, comprising: a rotatable drum including a peripheral surface and a plurality of recesses in said surface; retaining means for retaining a plurality of carriers in said recesses; said drum adapted for connection to one pole of an a.c. voltage source; a counter electrode spaced from and extending about a first portion of said drum defining a polymerization chamber, said counterelectrode adapted for connection to another pole of the a.c. voltage source and including first supply means communicating with the space between said counterelectrode and said drum for attachment to a monomer gas supply, said polymerization chamber operable to apply a polymer coating on the electrical component structure traveling therethrough; first and second air-locks at respective circumferential ends of said counterelectrode, each of said air-locks including a port communicating with said polymerization chamber for the evacuation of residual monomer gas; a metallization chamber extending circumferentially about a portion of said drum between said first and second air-locks; and metallization means in said metallization chamber for applying a metal coating to the electrical component structure traveling therethrough.
