Lives at Risk

You raise a great point - a point that is often lost in the cacophony of lawmakers and industry discussing how to address the issue - that in the real world counterfeit components pose a real and immediate threat to the health and well-being of the men and women who rely on systems to perform.

I work for an independent distributor (Secure Components) who has aggressively pursued counterfeit avoidance certifications (we are AS6081 certified and DLA QTSL approved). We pursued these certifications because we care about doing the right thing, which in this case also happens to be good business. Too often buyers tell us they do not want to buy from us because they do not want to pay the cost of destructive testing.

They fail to understand that the cost of testing components procured from the secondary market is far less than the potential cost associated with incorporating a counterfeit part into their system, The risk of a counterfeit component infiltrating the supply chain outweighs the cost of confirming the authenticity of a part,

Although representing reused parts as new is illegal and can cause accidents, calling them "counterfeit" is misleading. I would recommend that terminology and infraction reporting distinguish between "counterfeit" (made by an unauthorized manufacturer), "used", and "misrepresented" (genuine component of a different grade or revision level) components. A clear understanding of the incidence of different categories of fraudulent parts could help direct corrective action. Better distribution channel controls, device authentication, and tamper evident features are all possibilities once we know what we need.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
