Abstract: A printing table arrangement includes at least one printing device for printing of substrates, at least one printing table, a first transport device to transport the substrates being printed in a first plane, and a lifting device to move the first transport device with the first plane between a printing plane assigned to the printing device and a transport plane lying underneath. The printing table has a second transport device to transport substrates in a second plane beneath the first plane, in which the fixed spacing between the first plane and the second plane corresponds to the spacing between the printing plane and transport plane.

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).
