Salem, N.H. Seica Inc. has introduced the Aerial series of automatic test systems targeted at circuit board repair. The flying probe test system series is comprised of the Aerial M2 and Aerial M4 models. These test systems provide high-speed testing with automatic programming tools, operating with or without CAD data.
The multi-probe architecture 2 or 4 probes extends test capabilities to the detection of continuity faults such as broken tracks, opens caused by cold solder joints, and impedance problems on tracks caused by oxidized joints or by thermal and mechanical board deformation, said Seica. Analog signature analysis on circuit nodes is enhanced by a multi-frequency stimulus capability and precise analysis of the results via integrated DSP technology and FFT data processing.
Additional bipolar or quadripolar measurements on components, together with differential checks on IC junctions, generated automatically, offer expanded fault coverage and diagnostic resolution. The test systems also provide detailed fault diagnostics, together with repair actions.
For more complex boards, the Aerial system provides solutions for detecting "stuck at" type faults on active components (both analog and digital) via power on testing. The software automatically generates a series of stimuli and measurements for on-board
nets, based on the technology of the components present and their interconnections (derived from CAD data or manually generated), which enables the identification of the most often recurring faults on ICs. There is no need for manual programming, libraries or autolearn of a golden board, said Seica.
