AI Technical Summary
Technical Problem
Fluctuations in mask tension cause misalignment of solder during printing, leading to reduced print quality, and this impact varies by printing direction.
Method used
A print quality control system that includes an acquisition unit to measure deviations of solder from the target printing position and a correction unit to adjust the relative position of the mask and substrate for each printing direction before misalignment occurs, using a second threshold value smaller than the misalignment threshold.
Benefits of technology
The system effectively corrects the relative positions of the mask and substrate, reducing misalignment and improving print quality by addressing mask tension fluctuations.

Abstract
To provide a print quality control system that can correct a relative position of a mask and a substrate for each printing direction before the deviation of solder printed on the substrate from a target printing position reaches a threshold value for determining solder misalignment.SOLUTION: A print quality control system includes an acquisition unit and a correction unit. The acquisition unit acquires, for each printing direction, a deviation of solder printed on a substrate through an opening in the mask by a squeegee sliding over the mask from a target printing position. When the deviation acquired by the acquisition unit exceeds a second threshold set smaller than a first threshold for determining misalignment of the solder, the correction unit corrects a relative position of the mask and the substrate for each printing direction to reduce the deviation.SELECTED DRAWING: Figure 3
