The application relates to a doctoring unit for a printing apparatus for printing flat substrates, in particular circuit boards, wafers, or solar cells, comprising two doctor blades, which extend parallel to one another and are pivotably mounted. It is provided that the doctor blades are operatively connected to a gearing, which is formed in a self-locking manner and can be coupled or is coupled to a drive device.

Doctoring unit for a printing apparatus

A printing machine for printing on planar substrates, in particular circuit boards. The printing machine includes a printing table which extends in a horizontal plane and on which at least one substrate to be printed on can be arranged and at least one printing device assigned to the printing table. The printing device has a screen holder for an interchangeable printing screen and a doctor device assigned to the screen holder, wherein, by means of the doctor device, a printing material can be applied onto the substrate to be printed on through the printing screen. A screen magazine is assigned to the doctor device for storing at least one printing screen for the doctor device.

Printing machine and printing system having screen magazine for printing on planar substrates

A printing system for printing substrates, in particular circuit boards, such as wafer and solar cells, has a printing device, with a printing table on which the substrate can be positioned and a print head associated with the printing table for printing the substrates positioned on the printing table, has a feed device for feeding the substrates to be printed to the printing device, a discharge device for discharging the printed substrates from the printing device, and a plurality of substrate supports on which each of the plurality of substrates can be supported. The feed device, printing device and discharge device convey the substrate supports with the substrates located thereon. The feed device collects plurality of substrate supports and feeds them to the printing device. The printing device prints the substrates on the collected substrate supports, and the discharge device separates and discharges these collected substrate supports.

Printing system for printing substrates, method for operating the printing system

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.

Printing table assembly, method for operating a printing table assembly

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: &#x2014;applying a printing screen to the substrate, &#x2014;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, &#x2014;separating the printing screen and the substrate by lifting these parts off from one another, &#x2014;inserting an optical inspection unit between the printing screen and the substrate, &#x2014;checking the printed structure in terms of the printing paste thickness thereof by means of the inspection unit, &#x2014;ending the printing when the result of the printing corresponds to at least one preset value. The invention furthermore relates to an inspection unit () and a printing device ().
