Seica marries flying-probe and boundary-scan test methods
The FlyScan module combines flying-probe and boundary-scan capabilities in a single test program.

Seica, in partnership with Temento Systems, has developed the FlyScan module to enable the integration of boundary-scan testing with flying-probe test systems. According to the company, FlyScan exploits the specific benefits of flying-probe and boundary-scan testers, creating a single test program that uses the full capabilities of both—not as two entities working independently, but in a fully integrated system.
The FlyScan module, which is available on all of Seica's Pilot and Aerial flying-probe systems, offers the following capabilities:
- Automatic generation of the test program in one software environment, Seica VIVA;
- Automatic creation of the boundary-scan program, including nets that are not of the JTAG type, using the extended-test function and the flying probes to transform them into JTAG-testable nets;
- Automatic elimination of test redundancies;
- Automatic fault diagnostics, with real-time generation of additional tests executed by the flying probes for the specific identification of the faulty component;
- Generation of a single test report in the VIVA environment; and
- Management of the faults detected by the boundary-scan test in the Seica Repair Station environment.
Compared to the conventional approach of subjecting a board
first to a standard flying-probe test and then to a boundary-scan test on a
separate test station, the core interaction between the worlds of flying-probe
and boundary-scan test enabled by the FlyScan module provides improved test
results, easily measurable in terms of speed, throughput, and fault coverage.
