Developing effective and efficient
test methodologies
SRXGlobal’ Design for Testability
(DfT) process aims to develop an optimum
test strategy which ensures that an effective
and efficient test routine is in place
prior to commencement of full scale production.
The early detection of any potential issues
relating to component and process defects
is also an objective of this process.
Many
factors affect the selection of the optimum
set of test methodologies, including the
product group/technology, product volume,
product life, reliability requirements,
development cost and pay back. SRXGlobal' highly skilled
engineering team will be pleased to assist
you with the determination of the most
appropriate test methodologies for any
product.
Design for Testability analysis utilisting eMTestExpert
tools and Testability / Test Coverage reports for ICT are
offered to provide insight into the most suitable test strategy.
SRXGlobal utilises proven approaches
and techniques to ensure its various testable
systems. The company can provide you with
the following selection of test methodologies:
ICT: defects
in signal interconnections and component
placement identified using ICT test equipment,
Flying Probe, MDA testers and/or boundary scan technology,
as well as on-board chip programming capability;
AOI: A high resolution
Automated Optical Inspection system with line-scan technology
can check for presence; absence; shift/skew; misalignment;
tombstone; reverse polarity; bridging; insufficient solder and more;
Visual testing:
various product conformance criteria can
be determined visually using tools such
as magnification, cameras and templates;
Functional testing:
sub-circuit and complete design integrity
verified using manual, semi-manual and
fully automated functional testing equipment;
Integration testing:
designed to ensure that products interface
with one another in a fully configured
system using a range of manual and automated
procedures;
Heat soaking:
aims to determine product operational
thermal limits, to cause weak components
to be revealed and to verify the effectiveness
of product internal cooling/heating protection.
This is particularly important to a product
that will be exposed to changes in atmospheric
conditions. Passive or active humidity controlled
thermal cycling available.
