Patent ID: 8800440

Claim:
A screen print system built by coupling a first screen printer to a second screen printer, wherein the first screen printer positions a substrate having a plurality of first electrodes provided on respective bottom surfaces of a plurality of cavities formed in portions of an upper surface of a substrate main body and a plurality of second electrodes provided on the upper surface of the substrate body and brings into contact with the upper surface of the substrate a first mask having first pattern holes that correspond to the respective first electrodes and that are formed in each of a plurality of downwardly-protruding convex portions to be fit into the respective cavities of the substrate body, thereby subjecting the first electrodes to screen printing, and wherein the second screen printer positions the substrate subjected to screen printing by the first screen printer and brings a flat-plate-shaped second mask having second pattern holes corresponding to the respective second electrodes into contact with the upper surface of the substrate, thereby subjecting the second electrodes to screen printing, the screen print system further including a first cleaning unit and a second cleaning unit, wherein the first cleaning unit performs relative movement with respect to the first mask, thereby sequentially bringing a mask contact area, which is formed by stretching a paper member over an upper end of a paper member support section, into contact with lower surfaces of the respective convex portions of the first mask, thereby removing past adhering to the respective lower surfaces of the respective convex portions of the first mask, and wherein the second cleaning unit performs relative movement with respect to the second mask, thereby bringing the mask contact area, which is formed by stretching a paper member over an upper end of the paper member support section, into contact with a lower surface of the second mask, thereby removing the paste adhering to the lower surface of the second mask, and the first cleaning unit having a paper member winding-up unit that winds up the paper member after removal of the paste adhering to the lower surface of one of the convex portions of the first mask and before the paper member contacts a next convex portion to be subjected to removal of paste, to thus update the mask contact area, wherein the paper member is relatively fixed with respect to the paper member support section in a period during which the paste is removed, wherein the system further comprises a controller for actuating a movement of the first cleaning unit from the lower surface of the one of the convex portions to the lower surface of the next one of the convex portions after cleaning the lower surface of the one of the convex portions, wherein the controller actuates the paper member winding-up unit after removal of the paste adhering to the lower surface of the one of the convex portions of the first mask and before the paper member contacts the next one of the convex portions to be subjected to removal of paste.
