Recently, along with the labour cost rising step by step, the development and the use of the automation mechanical has risen , hence the simple work is being replaced by the automation mechanical gradually, and so is the Printed circuit board. Circuit board is the important part in our life. This paper will analysis the PCB designs which is used mostly in Printed circuit board industry. This research is to analysis failure mode of the equipment in design process. The equipment is divided into frame group, transport group, sucker group, jacking group, aligner group, pneumatic control circuit group, and register group. Find out all of the equipment failure mode to calculate what Risk Priority Number is. After finding the Risk Priority Number, it can be used in prophase of the design planning. This research makes analysis according to six sigma, and uses define phase and measure phase to analysis in six sigma. Fishbone Diagram and FMEA in design process are used in this research to exclude the failure mode of the design in all the step, which can reduce the aging in design.
