| Summary: | 碩士 === 國立臺北科技大學 === 工業工程與管理系EMBA班 === 104 === In the modern society, public health has been improved. With the development of medicine, people now can live longer. The rapidly aging population has influences on family structures, works, lifestyles, and consumption patterns of people. Sound and complete medical care services are essential. Moreover, due to the changes in information technology, traditional medical care models have been transforming with improved medical technologies and instruments. And remote medical care has been rising.
The flexible measure sensor pad is a remote medical care product. It can detect a care receiver’s movements of lying on the bed or leaving the bed, and warning his caregiver through the device itself or the emergency calling device of the medical station.
The main part of the manufacturing process of the flexible measure sensor pad is to print circuits using the screen printing technology on the materials. Generally, the parameters for screen printing are determined using the trial-and-error method along with engineers’ experiences. However, there are a lot of parameters for screen printing to be set. Thus, different engineers may lead to different manufacturing process improvement results. This study aimed to propose a mechanism to determine the combination of parameters for screen printing. First of all, the research problem was defined through the discussions with the experts from the industry. Then the Delphi method and the hierarchical analysis method were applied to determine the important process factors. The levels of the parameters were determined based on the engineers’ experiences. Next, the Taguchi method was adopted for experimental design and the data of the experiments were collected to find the optimal solution. Using the mechanism proposed by this study, it was obtained that the L36 orthogonal array should be used for experimental design. By calculating the S/N ratios, the optimal combination of parameters was found. With this combination, the standard deviation of the film thickness reduced from 0.88255 to 0.65130.
