Abstract: A ring structure on a package substrate is divided into at least four different components, including a plurality of first pieces and a plurality of second pieces. By dividing the ring structure into at least four different components, the ring structure reduces flexibility of the package substrate, which thus reduces stress on a molding compound (e.g., in a range from approximately 1% to approximately 10%). As a result, molding cracking is reduced, which reduces defect rates and increases yield. Accordingly, raw materials, power, and processing resources are conserved that would otherwise be consumed with manufacturing additional packages when defect rates are higher.
