发明名称 I/O connection scheme for QFN leadframe and package structures
摘要 Methods, systems, and apparatuses for integrated circuit packages and lead frames are provided. A quad flat no-lead (QFN) package includes a plurality of peripherally positioned pins, a die-attach paddle, an integrated circuit die, and an encapsulating material. The die-attach paddle is positioned within a periphery formed by the pins. The die is attached to the die-attach paddle. The encapsulating material encapsulates the die on the die-attach paddle, encapsulates bond wires connected between the die and the pins, and fills a space between the pins and the die-attach paddle. One or more of the pins are extended. An extended pin may be elongated, L shaped, T shaped, or "wishbone" shaped. The extended pin(s) enable wire bonding of additional ground, power, and I/O (input/output) pads of the die in a manner that does not significantly increase QFN package cost.
