Claim 7:
8. A device, comprising:
a die including:
a substrate having a first surface;
a first conductive structure on the first surface, the first conductive structure extending away from the first surface and including:
a second surface spaced apart from the first surface by a first dimension extending between the first surface and the second surface;
an opening in the first conductive structure;
a first wall surrounding the opening; and
a first diameter; and

a second conductive structure on the first surface, the second conductive structure extending away from the first surface and including:
a third surface spaced apart from the first surface by a second dimension extending between the first surface and the third surface, the second dimension being substantially equal to the first dimension; and
a second diameter being less than the first diameter;

a first solder portion on the second surface of the first conductive structure, the first solder portion including:
a first point furthest away from the second surface; and
a third dimension extending from the second surface to the first point;

a second solder portion on the third surface of the second conductive structure, the second solder portion including:
a second point furthest away from the third surface; and
a fourth dimension extending from the third surface to the second point, the fourth dimension being substantially equal to the third dimension; and

an electrical component including:
a first contact having a fourth surface with a first area, the first contact coupled to the first solder portion; and
a second contact having a fifth surface with a second area, the second contact coupled to the second solder portion, the second area is less than the first area.
