Therefore the demands of flexible printed circuit (FPC) board used for the product is getting more important as the products are getting lighter. Also, the width of wire width on the FPC is getting smaller. The accuracy and reliability of electrical inspection equipment is required to be better for the FPC fabrication. The objective of this research is to combine 3-axis image processing, angle tuning precision displacement technology for servo control, electrical test software, and precision test fixture automation equipment. An automatic-alignment electrical testing equipment for FPC testing process is developed. There are 2 different parts to be evaluated in this research. The throughputs are 48 and 47 panels by using traditional manual equipment. The throughputs are 101 and 96 panels by using automatic equipment developed in this research. According to experiments, the productivity are increased by 104% and 110% and manual operation costs are reduced.
