Beschreibung
Zusammenfassung:	A paste dispenser having detection sensor for wire breakings and/or short circuit of pattern is provided to measure the wire breakings and/or short circuits of the pattern formed on a substrate, and to again apply the paste to portions of the substrate with breakings and/or the short circuit in order to correct the portions, thereby minimizing production of inferior products. The paste dispenser includes: a substrate for forming paste pattern; a head unit(50) equipped with nozzle(51) for discharging the paste on the substrate; second measurement sensor(200) for determining whether there is wire breaking or short circuit in the coated paste pattern or not ; and a control part which again applies the paste to portions of the substrate with the breaking or the short circuit according to a result of the measurement by the second sensor. The dispenser further has a first supporter for fixing the head unit and a second supporter for fixing the second sensor. The second sensor is mounted on the head unit.
