The Ultrasonic Industry Association (UIA) routinely holds "Virtual Collaborations" which are interactive webinars hosted by industry professionals featuring varying topics related to ultrasound, ultrasonics, transducer manufacturing and tuning, piezo materials, etc.

The most recent Virtual Collaborations was presented by Rasmus Lou-Moeller and was titled "Lead-free Piezo Developments." This presentation contained information on the progress and comparisons of various lead-free piezoelectric materials and PZT compositions and the current status of lead containing materials in electronic components and systems related to the RoHS Directive, as we have been following. Mr. Lou-Moeller has also been involved directly with the “Umbrella Project”. (for more information on Umbrella Project please see the Newsletter Archive or follow THIS LINK to the February 2021 newsletter directly.)
Mr. Lou-Moeller’s Lead-free and RoHS update was quite extensive and included the following: 

  • A listing of products that were outside of the RoHS scope - some examples of which are military applications, space applications, transportation applications, and certain medical applications. (a complete list is widely available by internet search)

  • A discussion of the European/Japanese Electronics Industry’s “Umbrella Project” that presents supportive input to the RoHS Committee on hazardous material containing products. The Umbrella Project was initiated in 2013.

  • Mr. Lou-Moeller also presented data on PZT materials compared to a variety of lead-free materials and commented of the advantages and disadvantages of these materials.
 
The current status of Exemption 7c remains in flux. It has been confirmed through Mr. Lou-Moeller that the formal recommendation to the European Commission has been to EXTEND the 7c exemption. At this time, there is no reason to believe this recommendation will not be adopted, however it has not formally been announced that the exemption carries on.
