Abstract

System, jetting assembly and method for jetting viscous medium onto a substrate. The system comprises a plurality of ejector devices for jetting individual droplets of viscous medium onto the substrate, a plurality of viscous medium containers for holding and providing the viscous medium to be jetted, at least one holder for holding containers and ejector devices in a jetting machine, and a jetting machine.

Claims

1. A system for jetting viscous medium onto a substrate, comprising:

a plurality of ejector devices for jetting individual droplets of viscous medium onto the substrate,

a plurality of viscous medium containers for holding and providing the viscous medium to be jetted,

a receptacle for receiving and collecting viscous medium residue produced during said jetting of individual droplets,

at least one holder for holding containers and ejector devices in a jetting machine, and

a jetting machine.

2. An assembly for jetting viscous medium onto a substrate, comprising:

an ejector device for jetting individual droplets of viscous medium onto the substrate,

a viscous medium container for holding and providing the viscous medium to be jetted,

a receptacle for receiving and collecting viscous medium residue produced during said jetting of individual droplets, and

a holder for holding said ejector device, viscous medium container and receptacle as one aggregate unit.

3. A method of jetting viscous medium onto a substrate, comprising the steps of:

providing an ejector device for jetting individual droplets of viscous medium onto the substrate,

providing a viscous medium container for holding and providing the viscous medium to be jetted,

providing a receptacle for receiving and collecting viscous medium residue produced during said jetting of individual droplets,

providing a holder for holding said ejector device, viscous medium container and receptacle as one aggregate unit,

assembling said aggregate unit,

mounting said unit in a jetting machine, and

jetting droplets of viscous medium onto a substrate.
