Test Systems repair electronic boards with/without CAD data.October 11, 2007 -
Models Aerial M2 and Aerial M4 automatic test systems detect continuity faults on electronic boards as well as stuck at type faults on active components, both analog and digital, via power on testing. Multi-frequency stimulus capability and analysis of results via integrated DSP technology and FFT data processing allows analog signature analysis. On-board software provides detailed fault diagnostics and indicates necessary repair actions.

The New Philosophy in Electronic Board Repair- The Seica Aerial Series
Salem, N.H.,- September 13th, 2007 - The repair of electronic boards coming
back from the field is managed in different ways by different companies. The
solutions adopted can range from expensive, customized, product-specific
test benches made up of a combination of external instruments, to low-cost
fault detection systems with limited capabilities.
A new, professional and innovative solution is now available in the form of
Seica's Aerial series of automatic test systems, which provide, at long
last, a cost effective and, at the same time, efficient solution for
repairing electronic boards.
Coming from years of experience in providing market-leading flying probe
test systems, the Aerial series (comprised of two models, the Aerial M2 and
Aerial M4) provide high speed testing combined with powerful automatic
programming tools, operating both with, or without CAD data. The
multi-probe architecture (2 or 4 probes) of the Aerial systems extends test
capabilities to the detection of continuity faults, such as broken tracks,
opens caused by cold solder joints, impedance problems on tracks caused by
oxidized joints or by thermal and mechanical board deformation. Analog
signature analysis on circuit nodes is enhanced by multi-frequency stimulus
capability and precise analysis of the results via integrated DSP technology
and FFT data processing. Additional bi or quadripolar measurements on
components, together with differential checks on IC junctions, generated
automatically, further expand fault coverage and diagnostic resolution.
One of the major advantages of the solution, and an innovative departure
from other test tools for repair, lies in test result interpretation. An
"expert" software environment processes test results and, on the basis of
predefined theoretical and practical rules, provides detailed fault
diagnostics. In addition, precise indications regarding the repair actions
to undertake are also determined reducing repair time and erroneous
component replacements.
As far as more complex boards are concerned, the Aerial system provides
innovative 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.
The cost-effectiveness achieved with the combination of simple, fast
fixtureless test generation, high level of fault detection, precise
diagnostics and repair indications enable the Aerial systems to set a new
standard for test solutions dedicated to electronic board repair.
