Abstract

In mobile industry, using a metal frame of devices is rapidly increased for thin and stylish designs. However, fabricating metal is one of the difficult processes because the sophisticated control of equipment is required during the whole machining time. In this study, we present an efficient multivariate monitoring procedure for the metal frame process in mobile device manufacturing. The effectiveness of the proposed procedure is demonstrated by real data from the mobile plant in one of the leading mobile companies in South Korea.
