    • A lead frame for manufacturing a semiconductor device has at least one set of substantially parallel leads having inner ends for connection to a semiconductor chip, outer ends for external connection and central portions therebetween and an outer tiebar interconnecting the outer ends and having an elongated guide hole therein, the longer dimension of the guide hole being parallel to the leads. A lead bending die has a locating pin respectively corresponding to and received in sliding engagement in each guide hole. The die maintains a center portion of them lead frame in a first plane and, with each locating pin remaining in sliding engagement within the respective, elongated guide hole, bends the central portions of the leads thereby to dispose the respective outer ends of the leads in a second plane, displaced from the first plane. The outer tiebar and the sliding engagement of the locating pin in the guide hole serve to prevent undesirable deformation of the leads as a result of the bending operation. The central surface portion of the die further includes a recess for receiving at least a part of a package which seals a semiconductor chip therewithin. The lead frame may include plural sets of substantially parallel leads with corresponding outer tiebars and associated guide holes extending from respective, plural edges of the package.
    • 用于制造半导体器件的引线框架具有至少一组基本上平行的引线,其具有用于连接到半导体芯片的内端,用于外部连接的外端和中间部分,以及连接外端并具有细长导向孔 其中,引导孔的较长尺寸平行于引线。 引导弯曲模具具有分别对应于每个引导孔中滑动接合并被接受的定位销。 模具将它们的引线框架的中心部分保持在第一平面中,并且每个定位销在相应的细长引导孔内保持滑动接合,使引线的中心部分弯曲,从而将引线的相应外端设置在 第二架飞机从第一架飞机上移开。 外拉杆和定位销在导向孔中的滑动接合用于防止由于弯曲操作引起的引线的不期望的变形。 模具的中心表面部分还包括用于接收密封其中的半导体芯片的封装的至少一部分的凹部。 引线框架可以包括多组基本上平行的引线,其具有对应的外拉杆和从封装的相应多个边缘延伸的相关联的引导孔。
