Novel 3-D MEMS Approach to Digital Printing Electronics

摘要

An industry push to increase display pixel resolution, demand for improved jetability of complex fluids, and requirement for longer ink jet service life has mandated the advancement of new technologies to meet these demands. Digital technology is being explored as a route to improving manufacturing flexibility, decreasing manufacturing cost and reducing waste of expensive materials. Spectra is responding to new manufacturing challenges by continuous improvement in current ink jets and by designing ink jet modules with single crystal silicon Micro-Electro-Mechanical (MEMS) manufacturing processes. As a result the SX-128 has improved drop placement accuracy, jetting operability, and chemical resistance. Recent developments with MEMS processes are enabling the efficient development of a new ink jet product family capable of servicing a broad range of dispensing applications. This presentation will describe the results of improvements to the SX-128 as well as initial results with our new M-class~(tm) dispensing modules.
