Substrate

A substrate, comprising:

• a dielectric insulation layer;
• a first metallization layer arranged on a first surface of the dielectric insulation layer;
• and
• a second metallization layer arranged on a second surface of the dielectric insulation layer, opposite the first surface,
• wherein the dielectric insulation layer comprises an outer edge extending between the first surface and the second surface,
• wherein the outer edge of the dielectric insulation layer comprises a plurality of first sections and a plurality of second sections,
• wherein along each of the plurality of first sections, a difference between a first distance and a second distance has a first value,
• wherein along each of the plurality of second sections, the difference between the first distance and the second distance has a second value that is different from the first value, and
• wherein the first distance is a distance between the outer edge of the dielectric insulation layer and an outer edge of the first metallization layer, and the second distance is a distance between the outer edge of the dielectric insulation layer and an outer edge of the second metallization layer.
