Zusammenfassung: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.

By cutting along the tie bar, dummy contact leads are separated from the device area array.
