A Relationship Between Product Quality and Body Information of Worker and Its Application to Improvement of Productivity

In this study, we analyzed a body information feature in the soldering process in order to develop an evaluative method of the worker skills. First, we found the three types body information features. The found features were the work position, the way to hold a soldering iron, and the effect of the dominant eye and the age. Using the features of the work position and the way to hold a soldering iron, we classified the work rank into four classes. As a result of evaluating operation time and the product quality for these classes, it was confirmed that operation time and the product quality were improved as the work rank improves.
