    Abstract: A semiconductor device has an element encapsulated in a resin mold. Metal leads protruding from the resin mold are solder plated except at the lead-tip end surfaces, and the exposed lead-tip end surfaces have an area less than half the cross-sectional area of the protruding metal leads. The semiconductor device is manufactured using a lead frame in which the metal leads are connected to a frame by plating bars having a thickness smaller than half the thickness of the metal leads. In another embodiment, the metal leads are connected to the frame by plating bars that extend sideways from the metal leads, and the end tips of the metal leads are entirely covered with plating to improve soldering wettability.

    Abstract: A contact tail for an electronic component compatible with surface mount manufacturing techniques. The contact tail is stamped, providing a relatively low manufacturing cost and high precision. High precision in the contact tails in turn provides more reliable solder joints across an array of contact tails in an electronic component. Further, the contact tail may be shaped to reduce the propensity for solder to wick from the attachment area during a reflow operation. Reducing the propensity of solder to wick reduces the chance that solder will interfere with the operation of the electronic component. Additionally, reducing the propensity for solder to wick allows pads to which the contact tail is attached to be positioned over vias, thereby increasing the density with which contacts may be attached to a substrate. The reliability with which electronic assemblies incorporating components using the contact tail is also increased when the contact tail is used in self-centering arrays.

    Abstract: The invention provides a shield structure that allows an easy installment of a shield case on a circuit board with more strength and firmness even if the shield case is warped or distorted. The proposed shield case comprises a frame member consisting of four sidewalls and a covermember covering a farther end of the frame member from the circuit board. The frame member comprises a supporting member for sustaining the frame member on the circuit board and end faces confronting the circuit board. The supporting member comprises three projections protruding from the end face toward the circuit board.
