1. A method, comprising:
providing a lead frame including a positive electrode end and a negative electrode end spaced from the positive electrode end, and a capacitor set including a plurality of stacked capacitor elements each having a positive electrode portion electrically connected to the positive electrode end and a negative electrode portion electrically connected to the negative electrode end; and
using a laser source emitting a laser beam to perform laser welding on the positive electrode end and the positive electrode portion to form a fusion connection therebetween to provide at least one laser welding area, wherein the positive electrode end of the lead frame has a first outer periphery, wherein the positive electrode portion of each capacitor elements has a second outer periphery, wherein the at least one laser welding area is formed on the first outer periphery and the second outer periphery, wherein a gap is formed between the first outer periphery and the second outer periphery, and wherein the gap is dip-coated in a fluoride anti-blushing agent at least three times.
