Support for In-Circuit Testers and Flying Probes
The benefits of boundary-scan are noticeable during all phases
of a product life cycle. By coupling the power of ScanExpress
boundary-scan tools with that of other production test tools
such as In-Circuit Testers (ICT), Manufacturing Defect Analyzers
(MDA), and flying probe testers, a complete, integrated solution
is now available that offers the combined advantages of all test
technologies.
Boundary-scan operates as the perfect companion to ICT or flying
probe test systems. Boundary-scan is capable of testing areas of
a printed circuit board (PCB) that are difficult to access due
to physical space constraints and loss of physical access, often
due to fine pitch components such as Ball Grid Array (BGA)
devices. Conversely, the ICT is able to check the
non-boundary-scan compatible portion of the unit under test (UUT).
The combination provides greater test coverage and more
visibility when faults are detected.
Corelis ScanReuse™ Methodology
Corelis ScanReuse methodology allows production and
manufacturing departments to reuse all boundary-scan
test and programming files created during the design and
prototype product phases. This methodology conveniently
allows tests that were developed on a standalone
boundary-scan development station to be directly ported
into test equipment that the production and
manufacturing departments already owns or may decide to
purchase in the future.
Reuse of Boundary-Scan Tests and ISP
Corelis provides its customers with the means to reuse
all the boundary-scan test and programming files created
with the ScanExpress system with the following testers:
Corelis has partnered with high profile test equipment
manufacturers such as Agilent, Teradyne, CheckSum, Seica,
Digitaltest, and others to integrate the ScanExpress
boundary-scan tools within these test systems.
Design and test engineers often invest considerable
effort creating boundary-scan tests for initial
development and prototyping. When the design is released
to production, this effort is typically duplicated by
redeveloping the same boundary-scan tests from scratch
for use on an ICT, flying probe tester, functional
tester, or MDA. The integration of Corelis ScanExpress
boundary-scan tools was designed specifically to
eliminate this redundant effort and hence unify
boundary-scan test procedures across the complete
product life cycle, saving time, effort and ultimately
dollars. Additionally, a more thorough test can often be
achieved since the design engineer has unique insight
into the details of the design that can be transferred
directly to a more complete and robust test procedure.
The test procedures passed down from engineering are
often matured and refined from usage, making them much
more valuable to the repair technician for fault
detection and analysis.
Boundary-scan tests, created during development and
executed on bench-top systems, can now be applied
directly in these test systems. The seamless integration
utilizes the tester’s native software to present faults
that are detected by the boundary-scan portion of the
test. Specifically, the advanced diagnostic capability
of the ScanExpress boundary-scan software identifies the
cause of the fault down to the net and pin level.
