    摘要: A system of mold locks (28, 30) is formed on a heatsink (2) of a packaged semiconductor to prevent/mitigate delamination. The mold locks (4, 12) anchor a plastic mold compound (34) that forms the protective cover for the packaged semiconductor die. The mold locks (4, 12) are miniaturized to allow the positioning of them within the flag portion of the heatsink (2) and leadframe (24) such that a semiconductor die can be anchored above the mold locks (4, 12) formed within the flag portion of the heatsink/lead frame (2, 24). The miniaturized size of the said moldlocks (4, 12 do not detract from the purpose of the die attach solder (36).

    摘要: A method by which leads of a semiconductor component are bent into their final shape using a roll forming process to bend the leads into the desired shape before separation of the individual components. The roll forming process achieves a final form by passing a lead frame holding a plurality of the semiconductor components through a series of form rollers which progressively bend the leads into the final shape. The method can be designed to cut the components free from the lead frame as a final step, minimizing the individual handling of the miniaturized components.

    摘要: method for making a mount for at least two electronic devices forming a first mounting surface (210) from a material (240), and forming a second mounting surface (220) from the material (240). The first mounting surface (210) is connected to, but spaced from, the second mounting surface (220) by a mounting surface distance (250). The method further comprises reducing the mounting surface distance (250).

    摘要: A duo-cavity multigang pot molding assembly (10) for encapsulating semiconductor devices having an annular cavity (11) to form a molded carrier ring and an inner cavity (12) adapted to receive the item to be encapsulated. An outer mold pot (16) provides encapsulating material for the annular cavity (11) whereas a separate mold pot (17) provides encapsulating material for the inner cavity (12). Encapsulating material for the mold pots (16, 17) may be the same or in a preferred embodiment, different. Molding apparatus (10) promotes improved process control by delivering encapsulating material with a lower and more uniform viscosity to both the annular cavity (11) and the inner cavity (12). Further, use of separate mold pots (16, 17) allows cost savings because a less expensive encapsulating material may be used for molding the molded carrier ring since a high purity encapsulating material is not needed.
