Abstract: In examples, a package comprises a semiconductor die having a device side and a bond pad on the device side, a conductive terminal exposed to an exterior of the package, and an electrical fuse. The electrical fuse comprises a conductive ball coupled to the bond pad, and a bond wire coupled to the conductive terminal. The bond wire is stitch-bonded to the conductive ball.
