Lead frame

Leadframe for a QFP package

Lead frames are the metal structure inside a chip package that carry signals from the die to the outside.

The die inside the package is typically glued to the lead frame, and then bond wires attach the die pads to the leads. In the last stage of the manufacturing process, the lead frame is moulded in a plastic case, and outside of the lead frame is cut-off, separating all leads.
