Abstract:
An electronic device, a lead frame, and a method, including providing a lead frame with a Y-shaped feature having branch portions connected to a dam bar in a prospective gap in an equally spaced repeating lead pitch pattern, and a set of first leads extending parallel to one another along a first direction and spaced apart from one another along a second direction in lead locations of the repeating lead pitch pattern, attaching a semiconductor die to a die attach pad of the lead frame, attaching bond wires between bond pads of the semiconductor die, and the first leads, enclosing first portions of the first leads, the die attach pad, and a portion of the semiconductor die in a package structure, and performing a dam bar cut process that cuts through portions of the dam bar between the lead locations of the repeating lead pitch pattern.
