In a previous blog, I discussed some of the factors behind the growing incidences of counterfeiting within the electronics industry. As noted, the industry has been teaming up with experts to fight the scourge with some modest success, but obviously there's more that can be done at the individual enterprise level. In this concluding blog on the subject, I offer eight steps companies can take to avoid buying fake parts and what they can do if they discover counterfeits in their inventory. (See: Steps to Creating a Counterfeit-Free Supply Chain.)
Procurement (supplier selection):
As part of your supplier selection process, you should seriously consider the type of supplier you want on your approved vendor list. No source can claim to be 100 percent secure, but the different component sources also have varying levels of risks. The Cyclops Electronics guide offers a series of questions that we would encourage buyers to ask their prospecting component suppliers, to help in understanding their background and history of counterfeit detection.
Receiving, inspecting, and examining goods:
Step 2 introduces potential buyers to the methods of counterfeiting, which are known to us and the ways in which we may be able to visually identify suspected parts. What we look for are methods used to disguise the counterfeit components as genuine pieces. Counterfeits can be difficult to spot at first glance and may often require more inspection. However, there can be clues on the components or in the accompanying paperwork that might help you. Be on the lookout for impossible date codes, discolorations, and any corrosion or peeling on the parts.
Quality specifications:
The Cyclops Electronics guide gives an overview to some certifications that you should expect a supplier to have, such as ISO 9001:2008 or AS5553 accreditations. These are designed to be strict requirements that distributors must conform to in order to mitigate the chances of receiving counterfeits in the supply chain.
Traceability requirements:
To protect themselves and their customers, component distributors should be 100 percent honest about the origin of the parts that they sell. Records regarding procurement should be maintained and kept accurate according to quality standard procedures. This information should be made available to customers when requested.
Testing for counterfeits:
There are many tests that can be done to detect counterfeit parts, and any serious component distributor should offer these services to customers. This could include electrical testing, such as the ABI electrical Sentry testing machine, or x-ray inspection. Alternatively, other methods include scanning electron microscopy (SEM) and XRF analysis, which is used to determine the chemicals found in a component to identify the RoHS status.
Training and certification:
Companies should be proactive in developing their own quality procedures to help curb the number of counterfeits in the supply chain. There are many organizations that can help you develop staff training programs that will give them an advantage in counterfeit detection. These organizations include the IDEA (Independent Distributors of Electronics Association) and the UKEA (UK Electronics Alliance).
Planning, systems, and procedures:
Develop an obsolescence program to manage product life cycles and assess the availability of genuine parts. Look at all the "trusted suppliers" of the parts and keep an eye on the availability of the parts. This will help you plan for obsolescence issues and avoid having to rely on "unknown suppliers" that make unrealistic claims about the availability of the parts you are looking for.
Reporting counterfeit components:
As mentioned earlier, many incidents of counterfeit parts in the supply chain go unreported as companies are concerned about refunds and reputation. Have the parts impounded or destroyed in order to break the cycle of counterfeiting. There are several associations that you can report suspected counterfeits to, including the ERAI (Electronic Resellers Association International) and the IDEA (Independent Distributors Electronics Association).
Components buyers have a moral obligation to report counterfeits if they discover them. Similar fake parts may have gone undiscovered in other supply chains and may have been used in electronic manufacturing elsewhere. These tainted products may prove highly unreliable or even dangerous. By reporting the discovery of counterfeits to one of the associations mentioned, they can inform their members to take extra precautions when buying those parts.

Testing may also have to include test for a specific application. I recently heard a story where a defense contractor was testing a COTS part for a defense appication. The part kept burning out. So, as many of our readers point out here, making sure something works is only part of the solution.
The ABI system is based on a software library of parts for comparison generated by ABI and not the original semiconductor manufacturer. The comparison they are doing to what they think is a good enough set of characteristics. It may or may not be the extent to which the original product was tested. It is better than doing no electrical test and probably reasonable for simple devices, but it does not test for long-term reliability and handling issues and it is not what the original OCM did for testing the product.
There is no easy pill to swallow on genuinely doing full electrical testing, specifically for long-term reliability and handling issues.
This ABI system is a nice baby-step, but it does not cover all the electrical testing issues and certainly does not cover all parts.
DavidF, You are right and thanks for the clarification. I believe most experts on anti-counterfeiting would agree with the position that a quick and inexpensive test should first be carried out on suspected counterfeit parts before a more intense and likely expensive test is carried out. The most basic one is just to see if it works. If it doesn't work, it may be because of a variety of factors but at least it can be put aside for additional testing. This is also another way to isolate an entire batch for review.
Bolaji, I think we all agree that no one test alone is sufficient in all cases. I am just suggesting that one quick way to see if it is going to function is to plug it in and exercise it before spending the money for the other test methods whose capitol equipment costs are > 50k and often over 100K.
DavidF, People often regard warily any system or anyone that claims to be able to quickly test and confirm the authenticity of anything, not to mention parts. Some experts believe the component may even work as intended but does that mean it is genuinely from the vendor? There are counterfeits that are so well made they even fool the original manufacturer!
ddeisz, I think No. 4 question on your list is probably one of the most important ones the distribution market and customers are avoiding. Who's going to pay for tests and who will stand by the results of such tests. The component buyer isn't going to pay for tests because they believe they automatically should get authentic parts while the components suppliers will never admit to being used as the conduit for fake parts. Distributors too (unless they are shady ones) will not readily admit to being the source of fake parts entering the system. So, where does the buck stop?
I agree in order to minimise counterfeits entering the supply chain standard tests should be undertaken on electronic components by the distributor. Our in house electrical testing machine from ABI named the SENTRY counterfeit IC detector can help detect counterfeit components.
A wide range of packages can be tested including Dual In Line, SOIC, PLCC and BGA's. The machine allows us to measure the unique electrical signature of components allowing us to compare against known genuine components.
Also if we discover components that we believe need further verification, we will offer further analysis such as X Ray & X Ray Fluorescence testing, Destructive Analysis, Thermal Cycle Testing, Burn In and Fine Gross Leak.
The electrical testing is standard within the Cyclops quality procedures and as mentioned, once again, no test can guarantee 100% that a component is authentic. However, all measures should be taken to minimise the risk.

I know of a test dystem that verifies components fast and accurately to their Specs. No false positives or negatives. Liobrary of components is over 50K parts!!!

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.
While no one really can accurately predict the future, we can take guidance from another Drucker saying which is the best way to predict the future is to create it.
You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically.
Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions?
Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
