METHOD FOR ALIGNING SUBSTRATE FOR PASTE DISPENSER

摘要

A method for aligning substrates of a paste dispenser is provided to align the substrates accurately even though an application head support unit is distorted by any cause, thereby minimizing errors during application. A method for aligning substrates of a paste dispenser comprises the following steps of: aligning the substrate by reading align marks(301); detecting application head support unit errors representing a distortion degree of an application head support unit(307); and compensating the application head support unit errors(311). In the detection of the application head support unit errors, plural sample patterns are applied(305) and the application head support unit errors are detected from the application result.
