| Popis: | 104 Copper clad laminates (CCL) is the main raw material for Printed circuit board (PCB), and both of these are inseparable. Given the base material are gradually increasing in demand in recent years, in order to meet the cloud industry, smart phone and vehicle products’ requirements. To cater to the increasingly demanding challenges, from the raw materials for the base material, manufacturing processes, to research and development of CCL, this will have to be further improved, keeping the property and quality of material in stable conditions has also become major concern of CCL. CCL manufacturing is a foundation of material industry; the composite material is made of Resin, glass fiber and Copper foil. Thus, the performance of shrinkage and expansion of base material is drawing PCB manufacturers’ attention. In this study, to obtain the optimized parameters to solve this issue by method of Design of Experiment (DOE), the researcher means to find out the best condition and apply it to mass production. The purpose is to offer high quality products for PCB. This research focuses on two target levels to the CCL process variation of Warp and Fill dimensional stability (DS). According to eight effect factors, every factor was set as two levels, then used 28-3 partial factor design of experiment to find the optimal solution to the CCL process. This is to confirm whether the optimization parameter is appropriate or not in this study. According to the experimental results, temperature, flame retardants, Glass Transition Temperature (Tg) and glass type are the main influences of experimental factors. These tend to affect the dimensional changing of the base material. When the key factors will be expected to effectively control the variation of that for the plant; in addition, the expenses of troubleshooting and production scrap will be reduced. |
