Influence of the densification parameters on screen-printed component properties

Standard screen-printing is a very versatile technology for the elaboration of thick films and hybrid circuits. However, in order to obtain components with particular properties such as gas sensors, varistors, PZT-based pyroelectric sensors, super-thick copper pads, etc., a better control of the layer compacity is necessary. This has been made possible, thanks to the preparation of specific inks and thanks to the development of new fabrication processes. Most examples will be drawn from our own experience.
