  • Publication number: 20140001618
    Abstract: One embodiment is directed towards a method of manufacturing a packaged circuit. The method includes partially etching an internal surface of a lead frame at dividing lines between future sections of the lead frame as first partial etch. One or more dies are attached to the internal surface of the lead frame and encapsulated. The method also includes partially etching an external surface of the lead frame at the dividing lines to disconnect different sections of lead frame as a second partial etch, wherein the second partial etch removes a laterally wider portion of the lead frame than the first partial etch of the internal surface; and partially etching the external surface of the lead frame as a third partial etch, wherein the third partial etch overlaps a portion of the second partial etch and extends deeper into the lead frame than the second partial etch.
