发明名称 Apparatus for shaping outboard terminals of surface-mountable circuit modules
摘要 The present invention is directed to a method and apparatus for bending and cutting outboard terminals, or leads, of surface mountable integrated modules applied to a carrier frame wherein slots are cut in the carrier frame so that retaining webs remain between the slots and the circuit modules. Each of the retaining webs interconnects the outboard terminals along one side of the circuit module to stabilize the terminals during a subsequent bending of the leads. A combination cutting and bending die is moved downward to cut the retaining webs free from one another and to bend the leads into their desired shape. The retaining webs and any excess length of the outboard terminals is then trimmed off, all while the circuit module is held in a hold-down part so that no stresses are transferred to the chip module during bending.
