ABSTRACT:
A jetting device and a method of jetting droplets of viscous medium onto a substrate. The jetting device includes a jetting outlet through which the droplets are jetted. The jetting device further includes a wall located at the jetting outlet, downstream of the jetting outlet seen in the jetting direction. The wall is provided with an orifice through which jetted droplets are permitted to pass through. A gaseous flow is provided within the space past the jetting outlet such that an adverse effect on the performance of the jetting device is prevented, the adverse effect resulting from the accumulation of viscous medium residue at the jetting outlet.
