The EventManager tool for the Flying Scorpion helps to bridge the gap between low and high-volume testing. For the latter, in-circuit testers were applied due to the higher throughput requirements that flying probes cannot meet. The bed-of-nails test, however, is clumsy and may provide limited access to the board, and changes to the fixture cannot be provided in short-term. The Flying Scorpion with the EventManager automatically adjusts the required test coverage to the situation and therefore keeps cycle times short. After a product changeover or during a start-up, the entire test program is executed. Once a manufacturing process is stable, the tool provides real-time ability to react to events in manufacturing. So components will be tested selectively depending upon the events having taken place on a board. Such an event can be the replacement of a feeder/reel at a placement system; and component verification helps to ensure product quality. The flying prober tests all relevant components on the affected boards only. The placer or a shop-floor management system forwards the process data to the tester to initiate an event which is described by board type and variant, serial number, details of the PCB, etc. The LoadManager, integrated into the tool, recognizes product changes in the line and automatically creates and loads the appropriate test program. All necessary adjustments to the flying prober are also made. Besides the automated mode for in-line manufacturing, there is also the capability of testing boards manually and selectively for analysis or repair. The operator uses a graphics to choose the board and the components based upon part number or reference designator and then starts the procedure. Test results and parameters can be transferred to a quality-management or tracking system, becoming the basis for reports and statistical analyses. For a comprehensive test strategy, the flying prober can be combined with AOI and AXI systems. The tool can be retrofitted to existing Flying Scorpions.
