发明名称 IC leadframe processing system
摘要 An IC leadframe processing system for use in an IC manufacturing system, whereby IC leadframes of different types can be subjected to various lead machining processes by a single processing system without a need of various types of cutting and bending dies. The topmost leadframe is separated by a separating device one by one from a stack of leadframes stored, each having a plurality of IC chips connected thereto. The leadframe is cut into each individual packaged IC by a leadframe cutting device. Lead wires of each packaged IC are subjected to pinch cutting, dam cutting and end cutting by a cutting die and then bent into a Z shape by a bending machine.
