Patent ID: 7867291

Claim:
A method of forming a solid electrolytic capacitor assembly, the method comprising: providing a solid electrolytic capacitor element comprising an anode body containing tantalum or niobium oxide, a dielectric layer overlying the anode body, and a conductive polymer layer overlying the dielectric layer, wherein an anode lead extends from a surface of the capacitor element; applying a light reflective layer to at least the surface of the capacitor element from which the anode lead extends, the light reflective layer overlying the conductive polymer layer, wherein the light reflective layer contains a plurality of reflective particles; providing a lead frame that defines a cathode termination and an anode termination; electrically connecting the conductive polymer layer to the cathode termination; laser welding the anode lead to the anode termination; and encapsulating the electrolytic capacitor element so that at least a portion of the anode termination and the cathode termination remain exposed.
