摘要: A leadframe including a die pad, leads, an outer frame, connecting bars and grounding bars is provided. Each of the grounding bars is suspended between two connecting bars by being connected with branches of the two connecting bars, such that the grounding bars are spaced by the die pad. The leadframe and the chip package of the present invention can permit a great design variation.

摘要: A chip package structure includes a die pad of which at least a notch is formed on at least one side and opposite to a mold gate. The die pad contributes to accelerating the injection of an encapsulating material, so as to exhaust the air in the mold in time, before the encapsulating material solidifies during the molding step, thereby overcoming or at least improving the problem of defects such as air bubbles in the encapsulation.

摘要: A semiconductor package structure is disclosed. The structure comprises a die pad, a chip, leads, a recess, and an encapsulant. The chip is disposed on the die pad. The leads are disposed on a periphery of the die pad and electrically connected to the chip. The recess is formed on the top surface of at least one of the leads and extends to the outside surface thereof. The encapsulant is used for encapsulating the die pad, the chip, the leads, and the recess.

摘要: A Quad Flat No Leads (QFN) package includes a lead frame, a chip, an encapsulant, and a protective layer. The lead frame includes a plurality of leads. Each of the leads has a lower surface that is divided into a contact area and a non-contact area. The chip is configured on and electrically connected to the lead frame. The encapsulant encapsulates the chip and the leads and fills spaces between the leads. The contact areas and the non-contact areas of the leads are exposed by the encapsulant. The protective layer covers the non-contact areas of the leads.

摘要: Techniques are described for position source selection. In an implementation, an electronic device provides a variety of functionality including at least functionality to determine position. The electronic device may be further configured to select between a plurality of position sources to determine position based upon a variety of selection criteria. In an implementation, a last known position may be stored when position is being determined through the plurality of position sources. The last known position may be used as an alternative to determining position via the position sources when one or more of the position sources are unavailable. In another implementation, the last known position may be employed to automatically select one of the plurality of position sources to be used by the electronic device for determining position.
