Abstract

We have fabricated a unified Orifice Plate Assembly (OPA) for high-resolution inkjet printheads, which has orifices, ink flow channels, and reservoirs three-dimensionally in a single body, using single-step 3D photolithography followed by single-step electroplating. These three components are the core in inkjet printheads because they determine almost all of ink fluidics, especially the size and trajectory of an ink drop. Therefore, for high-resolution beyond 600dpi, a unified and high-precision orifice plate assembly is strongly needed.
