Abstract
A process control method is provided for a surface mount line including a solder printer for printing solder on a surface of a substrate, a solder print inspector for inspecting the printed solder and outputting printing quality data, a mounter for mounting components on the substrate with the solder printed, a mount inspector for inspecting a state of the mounted components and outputting mounting quality data, a reflow furnace for heating the solder to solder the components to the substrate, and a soldering inspector for inspecting a state of the soldering and outputting soldering pass/fail data. The process control method includes: retrieving the printing quality data, the mounting quality data, and the soldering pass/fail data from a primary recorder with the printing quality data, the mounting quality data, and the soldering pass/fail data recorded therein, calculating representative data for each said component from the printing quality data, and recording the representative data, the mounting quality data, and the soldering pass/fail data for each said component in a secondary recorder; and determining whether the solder printer and the mounter need adjustment by using the data of the components with the soldering pass/fail data indicating conforming among the data recorded in the secondary recorder.
