Abstract
(A1) Die Erfindung betrifft einen Aerosol-Drucker, der mindestens eine Zerstaeubungskammer und mindestens einen Druckkopf mit mindestens einer Duese aufweist, wobei diese unmittelbar oder ueber Verbindungsleitungen verbunden sind. Weiterhin weist der Aerosol-Drucker Prozessgas-, Transportgas- und Fokussiergasleitungen auf.

 

DE 102009007800 A1 UPAB: 20100825 NOVELTY - The printer has a sputtering chamber and a print head (6) with a nozzle that is connected directly or over connection lines. One of process gas, transport gas and focusing gas lines or the connection lines or the print head includes a gas or aerosol discharge reducing or increasing device e.g. pressure regulating valve, for interruption of aerosol transportation from the chamber to the nozzle. One connection line from the chamber to the nozzle is interrupted by a virtual impactor (4) for concentration of the aerosol. A vacuum pump is integrated over a suction line to suck the gas. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing line interruptions with a continuous aerosol printing method. USE - Aerosol printer for printing samples i.e. metal contacts, on a semiconductor i.e. solar cell (all claimed). ADVANTAGE - The process gas, transport gas and focusing gas line or the connection line or the print head includes the gas or aerosol discharge reducing or increasing device for interruption of aerosol transportation from the sputtering chamber to the nozzle in a short time, thus enabling production of the line interruptions, handling the printer in a simple manner, operating the printer in a disturbance-free manner, improving stability of the printer, and saving costs and resources of the printer.
