A print head includes a body, holding a droplet jetting device, a flexible electrical connection element, and an adhesive covering and securing first and second contact pad structures together. The droplet jetting device has an actuator for jetting a droplet of liquid from a nozzle of the droplet jetting device. The actuator is in electrical connection to the first contact pad structure. The flexible electrical connection element has, at one end, the second contact pad structure, which is mounted onto the first contact pad structure. The first and second contact pad structures each have an interface surface which contacts the interface surface of the other to form an electrical connection. At least one of the first contact pad structure and the second contact pad structure includes a recessed portion as compared to a wider portion positioned between the recessed portion and the interface surface.

A substrate plate is provided for at least one MEMS device to be mounted thereon. The MEMS device has a certain footprint on the substrate plate, and the substrate plate has a pattern of electrically conductive leads to be connected to electric components of the MEMS device. The pattern forms contact pads within the footprint of the MEMS device and includes at least one lead structure that extends on the substrate plate outside of the footprint of the MEMS device and connects a number of the contact pads to an extra contact pad. The lead structure is a shunt bar that interconnects a plurality of contact pads of the MEMS device and is arranged to be removed by means of a dicing cut separating the substrate plate into a plurality of chip-sized units. At least a major part of the extra contact pad is formed within the footprint of one of the MEMS devices.
