In a weird twist, some counterfeiters are passing off lead-free parts as though they are parts exempted from the RoHS directive. In a recent article in Components in Electronics, the compliance consulting firm, Design Chain Associates notes that some counterfeiters have re-labeled RoHS-compliant parts as containing tin/lead solder. Certain industries such as defense, aerospace and medical equipment are exempt from RoHS rules because tin whiskering in pure tin solder can cause problems in extended use of extreme environments.
Design Chain Associates notes that manufacturers can avoid much of the counterfeiting risk by sticking with known component manufacturers and known distributors, particularly franchised distributors.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
