On the Work Process Organization of Surface Mounted Component Printing

The arrangement of operations in a production line for mounting the surface components on a printed circuit board is discussed. The production environment has a wide range of di erent products, which causes frequent set-up operations. The overall productivity of the line depends heavily on how the printing operations are organized. Set-ups cause delays which can be cut down by selecting carefully the feeders for the components and by solving a suitable sequence for the products. Algorithms which solve both of these problems are presented along with a discussion of the mathematical 0/1 integer programming approach. The revision of the production planning system has had a major impact on productivity. An increase of ca. 58 percent in the number of component insertions per hour is observed.
