Abstract
A flexible circuit for use within a printhead assembly and to connect a printhead body to an external circuit includes a substantially planar portion having one or more layers of conductive material and having a top surface substantially parallel to a top surface of the printhead body. One or more integrated circuits can be mounted onto the planar portion. Multiple leads extend from each integrated circuit, the leads electrically connected to the printhead body. One or more arms are attached to, and substantially perpendicular to, the planar portion, each arm including one or more external connectors configured to connect to the external circuit.
Claims6
A circuit to connect a printhead body to an external circuit, the circuit comprising:
- a substantially planar portion including one or more layers of conductive material and having a top surface substantially parallel to a top surface of the printhead body, the planar portion including:
- a central portion;
- and
- two distal portions on either side of the central portion;
- where the two distal portions are attached to the top surface of the printhead body and the central portion is raised from and positioned directly over the top surface of the printhead body relative to the two distal portions;
- one or more integrated circuits mounted onto the planar portion;
- a plurality of leads extending from each integrated circuit, the plurality of leads configured to electrically connect to the printhead body;
- and
- one or more arms attached to the planar portion and each arm including a main portion substantially perpendicular to the planar portion and a distal end substantially parallel to the top surface of the planar portion, wherein each distal end extends toward a center of the planar portion such that the distal end is positioned over the substantially planar portion and over the printhead body, each distal end including one or more external connectors configured to connect to the external circuit.
