The piezoelectric ink jet technology becomes the best way to address specific markets in the printing industry like decoration, high quality label, packaging,….The technology is now mature and reliable and the inks used in the print head are more and more attractive. A digital ink jet print engine is now able to address the needs of many companies looking for high throughput, low printing cost and mainly flexibility.Starting from this point, some company coming from complete different world like semi-conductor, electronic, telecommunication are looking for the piezoelectric ink jet technology to use it not for jetting inks, but for jetting specific material like conductive, adhesive or insulation materials.One of the key of the success is to formulate and to adapt the rheology of these specific chemistry to make them compatible with the print engine.This paper will describe a complete module based on piezoelectric ink jet technology including different specific feature (like material re-circulation, specific high voltage pulse design,…) to facilitate and improve material jetting.The universal module for material jet application should help these new generation of piezoelectric ink jet users to be more efficient in the material definition and development. They only have to be concentrated on the chemical formulation dedicated to their need.IMPIKA thinks that one of the future of the industrial piezoelectric ink jet will be in the electronic field, and a good way to penetrate this market is to provide to this industry a simple, reliable and easy to use jetting module.
