Capacitor assembly package structure having outermost reinforcement structures

Abstract

A capacitor assembly package structure includes a first bottom electrode structure, a second bottom electrode structure, a capacitor assembly and an insulating package body. The second bottom electrode structure is separate from the first bottom electrode structure. The capacitor assembly is disposed on the first bottom electrode structure and the second bottom electrode structure. The capacitor assembly includes a plurality of capacitor elements electrically connected to each other, and each capacitor element has a positive electrode portion electrically connected to the first bottom electrode structure and a negative electrode portion electrically connected to the second bottom electrode structure. The insulating package body is configured to cover the capacitor elements of the capacitor assembly. Each capacitor element has a raised protruding structure disposed on the positive electrode portion to reduce a shortest vertical distance between the positive electrode portion and the negative electrode portion of each capacitor element.
