Quality management and workflow control in printed circuit board production at the TU Budapest

Production of printed circuit boards (PCBs) is a very complicated process. There are many checkpoints and phases during the whole production, where application of quality management functions is necessary and the occurrence of faults is rather high. Following the path of a faultless work piece can be easy, but it is more difficult if a defect occurs at a given checkpoint. The appropriate action should be determined: the piece can be discarded or repaired. Investigating how repairing influences the quality of the final product is also required. Modeling of the process helps in making these decisions and gives the solution for the given worker, who is not even aware of printed circuit production technology and its planning. This paper presents a multi-leveled process model of printed circuit production. The model is created with the Architecture of Integrated Systems (ARIS) tool.
