Abstract
The present invention relates to a control method for improving the productivity of a screen printer for an electronics-mounting machine. Thus, a screen printer according to this invention uses a recognition camera to inspect the results of printing of a circuit board concurrently with a cleaning operation of the rear surface of a screen, thereby enabling the effective use of time. This screen printer also enables cream solder to be automatically supplied to reduce the operation time by determining whether the next screen to be used is unused. During automatic screen replacement, this screen printer enables a desired screen stored in the corresponding stocker to be automatically specified in order to replace the current screen in response to a selected NC program.
