Low cost piezo printhead based on microfluidics in printed circuit board and screen-printed piezoelectrics

摘要

A printhead includes a printed circuit board (16) having at least one base layer, with at least one electrical trace (18), at least one fluidic passage (22) and at least one fluidic chamber (20) as part of the printed circuit board. The at least one electrical trace, fluidic passage and fluidic chamber are formed using printed circuit board manufacturing processes. An integrated circuit control chip (32) is attached to the printed circuit board using known printed circuit board techniques. At least one fluidic actuator (26) arrangement and aperture plate (34) are attached to the printed circuit board using known PCB attachment processes.
