Abstract:
Leadframe for a semiconductor package and manufacturing from such leadframe including a plurality of connection leads supported in a frame. Die mounting plate is centrally located in the leadframe and is supported by a plurality of support leads which are electrically connected to the die mounting pad and extending in a direction outwardly therefrom towards the frame. Each support lead is formed with a connection pad portion and a down set link portion. Each connection pad portion is spaced from the die mounting plate and is connected to a conductive bonding ground wire from a semiconductor device mounted on the die mounting plate. Each down set link portion is electrically connected to the die mounting pad and supports the die mounting pad in a spaced arrangement from the connection leads. The connection pad portion and the down set link portion overlap, in the direction of extension of the support lead.
