Abstract:
1. A substrate, connected to another substrate, wherein the another substrate has two bonding portions which are insulated from each other, and the substrate comprises: a base having an upper surface, a lower surface and a through hole, wherein the through hole passes through the upper surface and the lower surface; a lower metal layer disposed on the lower surface of the base, wherein the lower metal layer has an insulation region, an electrical bonding portion and a strengthening bonding portion, wherein the electrical bonding portion and the strengthening bonding portion are electrically insulated from each other by the insulation region, and the strengthening bonding portion enhances the bonding strength between the substrate and the another substrate; a lower covering layer covering the lower metal layer and exposing the electrical bonding portion and the strengthening bonding portion for respectively bonding the electrical bonding portion and the strengthening bonding portion with the two bonding portions of the another substrate; an upper metal layer disposed on the upper surface of the base and electrically connected to the electrical bonding portion via the through hole; and an upper covering layer covering the upper metal layer; wherein the substrate has an edge to which the electrical bonding portion and the strengthening bonding portion are adjacent, a part of the substrate that is close to the edge overlaps the another substrate, another part of the substrate that is away from the edge extends away from the another substrate, and the electrical bonding portion is located between the edge and the strengthening bonding portion.
