Method of manufacturing leadless integrated circuit packages having electrically routed contacts
Abstract:
A method of manufacturing a leadless integrated circuit (IC) package comprising an IC chip mounted on a metal leadframe and a plurality of electrical contacts electrically coupled to the IC chip. The IC chip, the electrical contacts, and a portion of the metal leadframe are covered with an encapsulation compound, with portions of the electrical contacts exposed on a bottom surface of the encapsulation compound. The electrical contacts of the IC package having metal traces connecting bonding areas on a top surface thereof and contact areas on a bottom surface thereof, wherein at least some of the bonding areas are laterally disposed from the contact areas connected thereto.
