Patent ID: 8584331

Claim:
A method for forming an ink jet print head, comprising: placing a jet stack subassembly comprising a plurality of piezoelectric elements into a press; aligning a plurality of flat, unembossed conductive pads of a flexible printed circuit (flex circuit) with the plurality of piezoelectric elements, wherein the plurality of flat, unembossed conductive pads are continuous with, and formed from a same conductor layer as, a plurality of flex circuit traces; and applying pressure to the flex circuit within the press to deform the plurality of flat, unembossed conductive pads into a plurality of contoured, embossed conductive pads wherein, during deformation of the plurality of flat, unembossed conductive pads within the press, electrical contact is established between the plurality of contoured, embossed conductive pads and the plurality of piezoelectric elements.
