  • Laser-cut lead-frame for integrated circuit (IC) packages
    Patent number: 12224181
    Abstract: One example described herein includes a method for fabricating integrated circuit (IC) packages. The method includes fabricating a plurality of IC dies and providing a conductive metal material sheet. The method also includes laser-cutting the conductive metal material sheet to form a lead-frame sheet. The lead-frame sheet includes at least one of through-holes and three-dimensional locking features. The method further includes coupling the IC dies to the lead-frame sheet and coupling the lead-frame sheet and the IC dies to packaging material to form an IC package block comprising the IC packages.
