Counterfeit electronics are a prevailing supply chain issue, which have continued to become more widespread
in recent years.
Critical systems have long life cycles and diminishing manufacturing source issues, making them a prime
for economically motivated counterfeiters. Counterfeit electronics create risks and life-threating issues,
when incorporated into such critical systems. Since most of the chips in the market today are not equipped
mechanisms to aid in counterfeit detection, physical inspection is the most relied upon approach. During
inspection, defects related to the exterior, interior, and material composition are extracted from the
under test, and these anomalies are used to determine if it is counterfeit. Physical inspection does not

There are many longstanding challenges associated with physical inspection. First and foremost, in
order to evade detection
counterfeiters evolve and improve their methods over time. This can result in new defects and/or
in the frequency of the defects found in counterfeit parts. There are few (if any) initiatives aimed at
such changes, making it difficult to develop accurate assessment of risk. Second, counterfeit testing
typically performed by subject matter experts (SMEs), which is time consuming, results in
results, and is difficult to adapt. Automated approaches that could relieve these issues need to be
Third, there are a diverse set of counterfeit IC types within the supply chain, all of which have their
unique defects that require a gamut of expensive tests/equipment to detect. Any research that could
the time and cost associated with physical inspection would be an immense help.
The main barrier towards overcoming the above challenges is a lack of data. Developing and
detection through physical inspection requires images and measurements from a variety of counterfeit

The defects that this website seeks to highlight are those commonly specified in
counterfeit standards (e.g., AS6171).
We refer to them as ‘counterfeit defects’ in the text below. Please note the following:
Although some of the counterfeit defects shown here may overlap with manufacturing and packaging
(e.g., those related to reliability, yield, serviceability, and ship-product-quality-levels), this
is in no way meant to track such defects. Manufacturing and packaging defects are already well
and such information is often kept proprietary (with good reason).
The appearance of any single counterfeit defect does not necessarily indicate that a component is
Similarly, it is impossible to determine if any components have been modified maliciously or
either at the foundry or while in the supply chain. The Counterfeit-IC.org Management team cannot
does not draw any conclusions relating to such questions on this website. We simply report the
defects that we (or other registered users) have found on components readily obtained in the
