Abstract: A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.

Abstract: A printing system for printing substrates, in particular printed circuit boards, includes a printing device having at least one printing table and a printing template assigned to the printing table. The printing system further includes a first pair of first slide elements and a second pair of second slide elements for aligning a substrate on the printing table. The first pair of first slide elements can be displaced counter to one another along a first axis.

The substrate can be fed resting on a transport device on two opposite side edge regions, can be first lifted from below for the purpose of processing through supports and pressed against corresponding hold-down pieces in the side edge regions, and can be clamped on the corresponding side edges of the substrate in this position, resting on the supports, between two clamping strips, whereupon the hold-down piece can be lowered to the side away from the substrate and the clamping strip and further below the region of the upper side of the substrate thus loaded, such that full-surface processing can take place.

Abstract: The present invention relates to a method for printing a substrate, in particular a printed circuit board, with a printing paste, in particular a solder paste, comprising the following steps: —applying a printing screen to the substrate, —printing the substrate using screen printing technology through openings in the printing screen so as to achieve at least one printed structure consisting of printing paste, —separating the printing screen and the substrate by lifting these parts off from one another, —inserting an optical inspection unit between the printing screen and the substrate, —checking the printed structure in terms of the printing paste thickness thereof by means of the inspection unit, —ending the printing when the result of the printing corresponds to at least one preset value. The invention furthermore relates to an inspection unit (1) and a printing device (2).
