Automatic troubleshooting on complex PCBs
Summary
This has enabled us to increase the test speed and positioning accuracy even more," says Hermann Reischer, Managing Director of Polar Instruments GmbH, explaining the additional benefits of the system. The flying probe test system compares the characteristics of a sample assembly with those of faulty boards using nodal impedance analysis. The new GRS550 is used for fault diagnosis in prototype construction, new product launches, small series and applications for which a traditional in-circuit test or multipin flying prober is too expensive. "This allows operators to easily generate important test results without having to carry out complex programming on fully automated systems, which are also usually oversized for these requirements," says Reischer. This enables the GRS550 to diagnose faults in all component technologies such as SMT, PTH, and BGA, with the system automatically positioning the test points on the accessible areas of the nets.
