A print head includes a substrate having a hole, a circuit on the substrate, the circuit having traces and a hole corresponding to the hole in the substrate, the hole forming a fluid path, and a raised structure on the substrate around the fluid path, the raised structure positioned to seal the circuit from the fluid path.

A printhead for a printer and methods for making the printhead. The printhead may include a driver module on a jetstack. The jetstack may include a plurality of holes formed therethrough. A first adhesive layer may be disposed on the jetstack. A diaphragm plate may be disposed on the first adhesive layer. A piezoelectric layer may be disposed on the diaphragm plate. A second adhesive layer may be disposed on the piezoelectric layer. A chip on flex may be disposed on the second adhesive layer.

Modular printhead sub-assembly

A flex circuit board provides islands of electrically isolated material surrounding openings in the flex circuit board to preserve fluid integrity of passageways passing through an electrically insulating layer of the flex circuit board. The electrically isolated islands surround exits of the passageways through the electrically insulating material and extend the passageways through an electrically conductive layer of the flex circuit board. Consequently, fluid passing through the passageways and electrically isolated islands in the flex circuit board is not subjected to electrical current.
