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.

There is provided a screen printer including: a squeegee device for spreading a cream solder over a mask having formed thereon a printing pattern configured of a plurality of through holes to force the cream solder through the printing pattern; a clamping device for holding a board that is conveyed to be placed under the mask; and a lift device for disposing the board with respect to the mask in relation to a vertical direction, wherein the clamping device includes a pair of clamping portions for holding the board therebetween from a width direction, wherein the pair of clamping portions includes individually detachable clamping members that are brought into abutment with lateral end faces of the board, and wherein the clamping members individually have two or more clamping surfaces that are brought into abutment with the board in such a way that the clamping surfaces can be converted.
