摘要： Methods and apparatuses for providing leadless leadframes with dummy contact leads are disclosed. A leadframe is described that includes an enclosed frame having two lengthwise portions and two widthwise portions. The leadframe also includes a device area array with dummy contact leads formed on the peripheral edges of the device area array. Furthermore, dummy contact leads are positioned along a tie bar such that they are directly opposite corresponding contact leads. By cutting along the tie bar, dummy contact leads are separated from the device area array.

摘要： Leadframe based packages, such as leadless leadframe packages are described that include an orientation indicator that is integrally formed with the leadframe. In one aspect, the leadframe includes a die attach pad, a plurality of contact fingers, a tie bar extending from the die attach pad, and an indicator stem extending from the tie bar. An integrated circuit die is mounted on the die attach pad and electrically coupled bond to associated contact fingers. A protective cap encapsulates the connectors and covers at least a portion of the die and contact fingers while leaving at least a portion of a bottom surface area of the contact fingers exposed to form external electrical contacts for the package. The protective cap leaves an identifying end of the indicator stem exposed through the surface of the protective cap to facilitate identification of a particular contact or region of the package. The described leadless leadframes may be produced in panel form which facilitates panel based packaging. In some embodiments, the indicator stem extends perpendicularly upward from the tie bar such that the combined thickness of the indicator stem and the tie bar is substantially the same thickness as the thickness of the contact fingers. Such devices may be formed by selectively etching the tie bars during formation of the panels.
