Cleaning device and method for silk-screen printing of plate elements for electronics or the like

A silk-screen printing station able to effect a silk-screen print, by means of a print paste, of impressions on silicon or alumina-based plate elements, such as of the type for electronics, or other types of plate for electronics, and comprising a net with incisions coherent with the impressions to be printed, through which the silk-screen print of the print paste is effected on said plate elements, said second station comprising a cleaning device that has removal means able to be positioned below the net so as to selectively remove the excess print paste from the net, wherein the removal means comprises at least a strip provided with at least an adhesive layer, wherein the strip is associated with unwinding means so as to unwind the strip in a controlled manner, and with means able to take the adhesive layer into contact, selectively, with at least part of the lower surface of the net.

An apparatus for loading, silk-screen printing and control of silicon or alumina-based plate elements, such as of the type for electronics, or other types of plate for electronics, comprising a first station to load the plate elements, a second station to effect a silk-screen print by means of a print paste, of impressions on the plate elements and comprising a net with incisions coherent with the impressions to be printed, through which the silk-screen print of the print paste is effected on the plate elements, and at least a third station to control the plate elements for electronics subjected to silk-screen printing, automated movement means being provided to move the plate elements between the first station, the second station and the third station, wherein the second station comprises a cleaning device that comprises removal means, able to be positioned below the net so as to selectively remove the excess print paste from the net, wherein the removal means comprises at least a strip provided with at least an adhesive layer, wherein the strip is associated with unwinding means so as to unwind the strip in a controlled manner, and with means able to take the adhesive layer into contact, selectively, with at least part of the lower surface of the net.
