Abstract: The main cause of product defection chip inductorlies in that the accuracy of printing process does not accord with the norm. Improving the printing precision is the key of production management. In view of the fact that printing preciseness is caused by many factors, an orthogonal experiment can be used to find the importance degree and reasonable level of factors, which can improve the process capability of printing. Applying this method to the printing of chip inductor in D Company, it is found that the order and the rational level of four factors and it concluded that: 1) the orthogonal experiment is effective in searching for quality improvement; 2) with the orthogonal experiment, the different degree of the four factors influencing printing preciseness is found, and the order is drying temperature> net height> speed> pressure; 3) the method can get the optimal parameters for better printing accuracy on chip inductor. The production capability of the chip inductor is improved obviously by using the optimal parameters.
