  • Patent number: 5665296
    Abstract: A method for assembling a plastic integrated circuit package. The method includes placing an integrated circuit die and lead frame into a mold. The mold has a first gate that is in fluid communication with a first side of the lead frame and a second opposite gate which is in fluid communication with a second side of the lead frame. The lead frame also has a mold flow hole adjacent to the gates. A plastic encapsulant is injected into both gates and flows across each side of the lead frame. The mold flow opening allows encapsulant to flow between each side of the lead frame.
