Claim 9:
10. A method for connecting at least one droplet jetting device of a print head to a controller,
wherein the print head includes:
a body holding the at least one droplet jetting device provided with an actuator for jetting a droplet of liquid from a nozzle of the at least one droplet jetting device, wherein the actuator is in electrical connection to a first contact pad structure positioned on an outer surface of the body,
a flexible electrical connection element having a second contact pad structure at one end, wherein the second contact pad structure is mounted onto the first contact pad structure, the first and second contact pad structures each have an interface surface, and the interface surface of one of the first and second contact pad structures contacts the interface surface of the other of the first and second contact pad structures to form an electrical connection, and
a non-conductive adhesive covering the first and second contact pad structures and securing them together,
wherein at least one of the first contact pad structure and the second contact pad structure respectively and/or each includes a recessed portion as compared to a wider portion positioned between the recessed portion and the interface surface,
the method comprising:
forming the first contact pad structure on a contact surface, such that at least one recess accessible in a direction parallel to the contact surface is formed in at least one side of the first contact pad structure;
positioning the second contact pad structure the first contact pad structure, wherein the first contact pad structure is provided on the body holding the at least one droplet jetting device and the second contact pad structure is provided at the one end of the flexible electrical connection element; and
applying the non-conductive adhesive to the first contact pad structure and/or to the second contact pad structure to secure them together, wherein adhesive flows into the at least one recess.
