Abstract
The present invention refers to a method and a device for jetting droplets of a viscous medium onto an electronic circuit board. According to the invention, the viscous medium is applied from a viscous medium supply container to an eject chamber through a tubular passage using a rotatable feed screw arranged within the tubular passage. The viscous medium is then jetted from the eject chamber through an eject nozzle by the rapid decreasing of the volume of the chamber.
