Electron Beam Imaging enhancement through the application of thin film technology

Electron Beam Imaging (EBI) print heads use a multiplexed array of electron guns to produce a latent charge image on a dielectric receptor. This image is developed and transferred to the substrate. Print uniformity requires that the electron guns deliver currents within a narrow range, and high resolution printing requires the miniaturization electrode matrix. To meet these challenges Delphax has embarked on an aggressive program to develop heads based on thin film technology. Well-established photolithographic techniques and favourable aspect ratios enable superior uniformity and addressability to be achieved. Highly automated manufacturing improves process control and reduces unit costs. In combination with the robust nature of EBI print engines, this makes the Delphax technology a formidable competitor in the marketplace.
