What is it about?
It is about the equipment selection of a fully automated and autonomous printed circuit board assembly (PCBA) (re) manufacturing cell using a robot. It also gives integration and interfacing details. It illustrates the importance of rework tool selection for a successful development of flexible (re) manufacturing cell.

Why is it important?
Despite the fact that FMS has emerged from machining and the traditional machine tool industry, flexible production method has been spreading to electro-mechanical assembly, test and inspection, welding, packaging, etc. This work is the first one to extend the application of flexible manufacturing cells (FMCs) to electronic assembly where both assembly and rework of defective electronic packages (components) are performed. It is important because; It provides important principles which should be the common interest of all parties involved in designing and implementing flexible production/manufacturing cells for reworking PCBAs. It presents the rework steps for standard surface mount (SM) and Through-Hole (TH) electronic components. It provides the selected equipment and devices that were used in developing world’s first autonomous robotic remanufacturing cell for reworking PCBAs populated with both SM and TH components. The equipment that was selected and used enabled batch size of one rework.
Perspectives
The design of most flexible manufacturing cells (FMCs) requires to deal in four interrelated design domains. These are (1)-Design of methods and procedures, (2)- Design and selection of mechanical systems, part, tools etc. (3)- Design of Cell Controller architecture, (4)- Designing integration and interfacing of tools, sensors etc. This paper concentrates on domain 2. It provides suitable tools and devices as a solution for developing world’s first autonomous robotic remanufacturing cell for reworking printed circuit board assemblies populated with both surface mount and through-hole components. As the designed system was manufactured and tested, the findings were also proven.
