dc.description.abstractAros Electronics is a company that develops and produces printed circuit assemblies from printed circuit boards. Recently Aros has made a large investment in a new surface mounting line. To maximize usage of their investment, it is important to analyze and improve the manual work around the machine, in order to make sure that the productivity is high. This master thesis report aims to analyze and give suggestions to improve the productivity, at a surface mounting line, at Aros Electronics. Most of the gathered data came from a work sampling study of the operators at the line, and from machine logs. Besides the gathered data, observations were also done during the sampling. The data was then analyzed to find the major losses in the system, which were the changeovers, machine stoppages and the breaks. By connecting the observations with the analysis, it was possible to determine that the lack of standardization, was the largest reason to the losses. To increase the standardization of the changeovers, a division of the work tasks and standardized worksheets were created; in addition, a SMED analysis was done, together these changes reduced the theoretic changeover by 91 %. A work division was created for the manual work besides the changeovers as well, in order to reduce the machine stoppages; however, the impact these changes can only me measured if they are implemented. Therefore no quantified data is available for the improvements of the machine stoppages. By rearranging the breaks, it should be possible to remove their impact completely. By combining the improvement from the changeover and the breaks a theoretical production increase of 84 % was reached.
