Purpose-built ink jet printheads are now recognized as useful tools in manufacturing where precision deposition is required. Piezoelectric drop-on-demand ink jet printheads offer the critical combination of high productivity, high reliability and jetting uniformity characteristics (drop volume consistency, velocity characteristics and jet straightness) for depositing a very wide range of materials dissolved or dispersed in organic or aqueous media. For example, ink jet printheads are key components in pilot production lines that manufacture RGB PLED displays for mobile phones. Even as ink jetting has gained a presence in display and electronics manufacturing, new opportunities are appearing that require smaller drops and increased productivity. Success with many of these new applications will require both process and fluid research and engineering.This paper describes Dimatix's approach to facilitate the development of manufacturing processes for both rigid and flexible substrates and development of new functional fluids.
