Abstract:
A semiconductor package includes a lead frame, a die, a discrete electrical component, and electrical connections. The lead frame includes leads and a die pad. Some of the leads include engraved regions that have recesses therein and the die pad may include an engraved region or multiple engraved regions. Each engraved region is formed to contain and confine a conductive adhesive from flowing over the edges of the engraved leads or the die pad. The boundary confines the conductive adhesive to the appropriate location on the engraved lead or the engraved die pad when being placed on the engraved regions. By utilizing a lead frame with engraved regions, the flow of the conductive adhesive or the wettability of the conductive adhesive can be contained and confined to the appropriate areas of the engraved lead or engraved die pad such that a conductive adhesive does not cause cross-talk between electrical components within a semiconductor package or short circuiting within a semiconductor package.
