Computer‐Integrated Automatic PCBA Rework

Abstract

Despite continuous efforts in improving process reliability in printed‐circuit board assembly (PCBA), a zero‐defect situation is difficult to achieve because of the complexity of the process and the multitude of components involved. PCBA rework is necessary in many companies due to economic as well as commercial reasons. Presents the intermediate results of a research programme aimed to investigate the technical and economic feasibility of extending the use of a robotic assembly cell to perform single‐board rework. Outlines various manual rework practices and the equipment available. Examines the role of industrial robots and machine vision in PCBA and defines the objectives and overall boundary of the research programme in automatic rework. Describes individual equipment selected to assist the robot, the layout and the manner in which it is used in the cell. Concludes with the development of the cell controller and the methods of equipment integration.
