    • A semiconductor device of the SOP type packaged on a lead frame and separated individually is fed into a lead-forming position by a holder, and the distal ends of leads arrayed on one side of the semiconductor device are imaged by a camera. The image data from the camera is processed by a recognition unit, which outputs the actual position of the semiconductor device. If the recognized actual position is different from the position to start forming leads, then a controller actuates the holder to eliminate the positional error and to position the semiconductor accurately in the lead-forming position. Based on data corresponding to the type of the semiconductor device, the lead bases of the leads are held by a lead-fixing finger assembly, and the distal end portions of the leads are bent arcuately by a lead-forming finger assembly, thereby forming the leads to a predetermined shape. Then, the leads on the opposite side of the semiconductor device are similarly formed to shape after the semiconductor device has been turned 180.degree. by the holder. To form the leads arrayed on four sides of a semiconductor device of the QFP type, two arrays of leads are simultaneously formed to shape by lead-forming devices disposed one on each side of the lead-forming position, and then two other arrays of leads are simultaneously formed by the lead-forming assemblies. Therefore, the leads can be formed to shape in two cycles of operation.
    • 封装在引线框架上并分离单独分离的SOP型半导体器件通过保持器馈送到引线形成位置,并且通过相机对排列在半导体器件的一侧上的引线的远端进行成像。 来自相机的图像数据由识别单元处理,识别单元输出半导体器件的实际位置。 如果识别的实际位置不同于开始形成引线的位置,则控制器致动保持器以消除位置误差并将半导体准确地定位在引线形成位置。 基于与半导体器件的类型相对应的数据,引线的引线基座由引线固定指组件保持,并且引线的远端部分通过引线形成指状组件弯曲地弯曲,从而形成 导致预定的形状。 然后,半导体器件的相对侧的引线在半导体器件被保持器转过180度后类似地形成为形状。 为了形成排列在QFP型半导体器件的四侧的引线,通过在引线形成位置的每一侧上设置的引线形成器件同时形成两个引线阵列,然后形成两个引线阵列 由引线形成组件同时形成。 因此,可以将引线形成为在两个操作周期内成形。
