And the lack of mentioning that the min cost will be in the 10's if not 100's of thousands of $$ for the remanufacture !!. There are benefits to both !!.. Military and others need to make contigency for min 25-50% replacement (service) parts adn possibly even 100% relative to the cost of the product !!. Brokers will always have benefits but hte decision to use Broker (Grey Market) need to be made by experienced/educated decision makers not just the bottom of the run purchasing officer who does not understand the consequences of bad decisions !.

If you were in a helicopter that went down owing to a faulty counterfeit part, or the victim of a faulty counterfeit medical appliance, I'm sure you would see things differently. Sure, 2% doesn't sound like a lot to you... but it's a lot to the people it affects. And it's also just an estimate.

I would just compare to cost of protection and the loss of income (or sth) due to counterfeit.

No mention of the DLA's Generalized Emulation of Microcircuits (GEM) program which can provide a form, fit, and function replacement for non-available microcircuits using current design and processing technologies? The GEM contract was awarded to SRI International (Cage Code / 03652), perhaps an oversight ? With regard to "Some companies are working on developing sophisticated identification technologies that can be included in the production of components, but these are also extremely costly." That's hogwash. The DLA recently Mandated the use of botanical DNA marking for high risk chips. It works and it is not "extremely costly". All in all, a very self-serving article if you ask me.

"...it is estimated that 2 percent of all the semiconductors sold last year were counterfeit. That doesn’t sound too threatening.." Who with half a brain would think 2% counterfeit parts is not threatening?

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.
