摘要：
A printhead assembly for an inkjet-printing device includes a printhead die and a flexible circuit connected to the printhead die. The printhead die includes a substrate, a first ground network electrically connected to the substrate, a device layer, and a second ground network electrically connected to the device layer. The first ground network and the second ground network are electrically isolated from one another within the printhead die. The first ground network and the second ground network are electrically connected to one another at the flexible circuit.
