Abstract:
1. A method for forming an electrolytic capacitor, the method comprising: positioning an anode lead of an electrolytic capacitor element adjacent to an anode termination, the electrolytic capacitor element comprising an anode, dielectric film, and electrolyte, wherein the anode lead extends outwardly from a surface of the anode; directing a laser beam through two or more refraction elements to laser weld the anode lead to the anode termination, wherein at least one of the refraction elements is oriented at an angle of from 0° C. to about 45° relative to an axis that is perpendicular to the direction of the beam; electrically connecting the capacitor element to a cathode termination; and encapsulating the capacitor element within a case so that at least a portion of the anode termination and cathode termination remain exposed.
