Abstract: An ink jetting structure includes a substrate that has a first surface and a second surface. A heater chip is mounted to the second surface of the substrate, and includes a first set of electrical contacts. A printhead circuit member has a third surface, a fourth surface, and an opening configured to receive the heater chip with the first set of electrical contacts of the heater chip being exposed through the opening. The third surface is mounted to the second surface of the substrate. The fourth surface has a second set of electrical contacts attached by wire bonds to the first set of electrical contacts. The third surface has a third set of electrical contacts electrically coupled to the second set of electrical contacts, and electrically connected to a flexible cable for coupling to corresponding contacts on a printer.
