Capacitor assembly package structure having outermost reinforcement structures

A capacitor assembly package structure, comprising:

• a first bottom electrode structure;
• a second bottom electrode structure separate from the first bottom electrode structure;
• a capacitor assembly disposed on the first bottom electrode structure and the second bottom electrode structure, wherein the capacitor assembly includes a plurality of capacitor elements electrically connected to each other, and each of the capacitor elements 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;
• and
• an insulating package body configured to cover the capacitor elements of the capacitor assembly;
• wherein each of the capacitor elements has a raised protruding structure disposed on the positive electrode portion, and the raised protruding structure of each capacitor element is configured to reduce a shortest vertical distance between the positive electrode portion and the negative electrode portion of each capacitor element;
• wherein the capacitor assembly package structure further comprises:
• a first inner conductive structure electrically contacting the positive electrode portion of each capacitor element, wherein the first inner conductive structure has a first bottom exposed side;
• a second inner conductive structure electrically contacting the negative electrode portion of each capacitor element, wherein the second inner conductive structure has a second bottom exposed side;
• a first outermost reinforcement structure adjacent to the first bottom electrode structure and disposed on a first side of the insulating package body;
• and
• a second outermost reinforcement structure adjacent to the second bottom electrode structure and disposed on a second side of the insulating package body.
