Boundary-scan boost for Huntron robotic probers

Last month Huntron and JTAG Technologies announced the integration of their test methods within Huntron’s range of prober enhanced analog signature products.

Huntron Tracker is synonymous with PCB fault detection using the technique known as analog signature analysis. Now users of this technology can take advantage of advancements made in the digital world that allow PCBs to be tested using built in logic circuits known as boundary-scan or JTAG, present in ICs such as FPGAs, CPLDs DSPs, and microprocessors.

By enhancing a Huntron system in a way that utilizes their robotic probe technology with boundary-scan capability, you can now further enhance the test coverage achieved with these iconic test systems.

It works by synchronizing the stimulus/measurement probe of the Huntron with a, JTAG Technologies generated, boundary-scan test vector. One example of how it works would be in testing the continuity of a PCB track from a JTAG/boundary-scan compliant part to an edge connector. Without a sense probe on the edge connector, you would be unable to detect an open circuit condition. The Huntron Robotic prober adds this facility in a flexible and low-cost manner.

Users will thus enjoy greater test coverage while maintaining fixtureless test access.
