Abstract: A substrate includes a dielectric layer, a first metal bar, a plurality of first traces, a plurality of first openings, a second metal bar, and at least one second opening. The dielectric layer has a first major surface and a second major surface opposite to the first major surface. The first metal bar is on the first major surface. The plurality of first traces are on the first major surface. Each first trace is connected at one end to the first metal bar. The plurality of first openings expose the dielectric layer on the first major surface and intersect a first trace. The second metal bar is on the second major surface. The at least one second opening exposes the dielectric layer on the second major surface and intersects the second metal bar. The first openings are laterally offset with respect to the at least one second opening.
