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.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
