Abstract: A frame includes leadframe units arranged in a matrix. Each leadframe unit has a die pad and tie bars connected to and extending from the die pad. Each tie bar includes an internal tie bar portion and an external tie bar portion. The internal tie bar portion of at least one tie bar includes a cut separating a part of the internal tie bar portion from the external tie bar portion. An out-of-plane bend in that part forms a mold flow control structure.
