Abstract

A printing system for printing three-dimensionally shaped structures, in particular on substrates such as circuit boards, wafers, solar cells, carrier substrates, printing tables, carrier plates, sintering plates or the like, has at least one printing device with a printhead having a squeegee device and a screen receptacle associated with the squeegee device for receiving a printing screen. A screen provision device has at least one screen magazine for storing multiple printing screens and a conveying device for conveying a printing screen from the screen magazine to the screen receptacle and from the screen receptacle to the screen magazine.

Abstract

A screen unit for a printing device for printing three-dimensionally shaped structures, in particular on substrates, printed circuit boards, wafers, solar cells, carrier substrates, printing tables, carrier plates, sintering plates or the like, has a frame holding at least one printing screen and is designed to be accommodated in a screen receptacle of the printing device, to be filled with a printing compound and to be subjected to the action of a squeegee for carrying out a printing process. The screen unit has, in or on the frame, at least one holding device for the squeegee, which is in the form of an exchangeable squeegee.
