The GRS550 flying probe test system, presented by Polar Instruments GmbH, advances from its forerunner, the GRS500, which is known for setting benchmarks in the electronics industry with its economical and user-friendly features. The new model showcases improved drive technology, which enhances test speeds and positioning accuracy, as per the manufacturer’s claims. Particularly effective in situations where adapter-based testing proves uneconomical, the GRS550 utilizes nodal impedance analysis and high-resolution imaging to compare a standard PCB with the one tested, facilitating effective fault diagnosis.

This system is tailored for prototype development, new product introductions, and small-batch production, where conventional in-circuit tests or multi-pin flying probers would incur high costs. It capitalizes on extensive CAD data and sophisticated fault diagnosis technologies to deliver comprehensive testing capabilities. With minimal setup time and lower costs, the system is designed for ease of use, allowing quick results without intricate programming. Its capability for rapid fault localization makes it a valuable tool in accelerating repairs of PCB assemblies and reducing the time to market for prototypes.

Equipped to manage all types of component technologies, the test system features a maximum fly height of 100 mm and dual live video cameras, ensuring a thorough fault analysis across SMT, PTH, and BGA components. This robust configuration enables precise and cost-effective troubleshooting, providing detailed coverage and reliability in fault detection across various PCB assemblies.

“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. “Fault analysis on complex electronic assemblies is not an easy task,” continues Reischer, adding: “The GRS550 was developed for rapid fault localization and thus enables fast and efficient repair of PCB assemblies. This saves the customer time and money and can reduce time-to-market, especially in prototype manufacturing.”
