Therefore, SMT ( Surfance Mount Technology) plays an important role in production. There are three major stpes in SMT: (1) Screen printer (2) Component placement and (3) Reflow oven. Among the entire SMT production process, Screen Printer is the most important key at quality and stability of the entire production. This study does analysis on several process parameters with a little experiment data, adopted table orthogonal experimental design and simple ANOVA from Taguchi Methods to get the optimal height parameter A3B2C1D1 and the optimal area parameter A2B1C2D1, then brought the height and area results from Taguchi Methods into these in order to carry grey relation. It compared the situation and correlation from changes of two factors, and found the optimal print parameter, which is A2B2C1D1 ( printing pressure 80N, printing speed 100 mm/sec, printing snap-off distance 0.2mm and printing snap-off speed 2mm/sec). The results accord with those states from thories and also conform to the goal vales.
