Digitaltest: Integrated Test Systems
Condor III flying prober.
Stutensee, Germany — Digitaltest GmbH is unveiling a new flying probe solution — the Condor III Innovation Package. Two testers integrated into one hardware system provide users with increased flexibility and lower cost-of-ownership for application-specific test requirements. This new test solution gives customers even more flexibility in floor space requirements, configured to meet the individual requirements of each test job.

End-of-line test bottlenecks frequently appear on high-volume product lines where assembly beat rates are now faster than test rates. In addition, manufacturing engineering teams require techniques that can maintain test coverage and not increase the unit cost of test.

The new Condor System provides users more flexibility by integrating an MTS30 rack into a Flying Probe Condor III system. The portable rack can easily be removed to be used separately as a standalone test system.

Thus, the system can operate as a flying prober or as desktop test system. Users can choose between the adapterless, fixtureless flying probe test, a bed-of-nails test using a fixture, or a combination — all with the compact size of a 19-in. system. Fault diagnosis and maintenance of the test rig is now made even more simple and speedy; the new system provides a status display to inform the user about the system's condition.

The new "four-wire measurement" technique is now available in a hybrid MTS500 Condor test system. Four-wire measurements allow for measuring extremely low resistance values, independent of system-inherent contact resistances. However, to perform a true "four-wire" measurement, two separate test access points are required at both net nodes of the component-under-test. By means of an additional second test wire per flying probe head, a so called "simulated four-wire-measurement" can be performed, even if the board-under-test doesn't permit access on two points per node.

This allows for compensation of system-inherent resistance offsets. Only the contact resistance between test nail and DUT remains uncompensated. It can be taken into account by an optional software offset parameter value. The recognition of fiducial marks has been greatly enhanced by using an adaptive lighting intensity. Even the most difficult images of fiducials can now be recognized.

The company is also showing the one-touch fixture for the MTS 180, developed to reduce the handling time for fixture exchange. Digitaltest now offers Reverse Engineering Service, to help clients to recover the design of the board and be able to repair and/or re-manufacture the PCBs again. The company has developed a specific tool for reverse engineering called "Digitizer", and with its help, the board data is re-created. A CAD file for the board can then be generated that has all the board components and nets and that can be used in repair and/or re-manufacture. Furthermore the company can also provide clients with the board schematics.

A brand-new service being offered in which Digitaltest handles all board test needs. Services include applications, test program generation, debug and fixture build. The company can use any test programs and fixtures from all manufacturers such as GenRad, Teradyne, Agilent (HP) on all of its testers quickly and easily.
