A recent article in Circuits Assembly notes that the European Commission (EC) of the European Union will review measures in the RoHS directive. The goal is to take into account scientific evidence. The deadline for comments is May 22. In the announcement, the EC noted that Article 6 of the RoHS directive calls for a review of the directive’s measures, taking into account, as necessary, new scientific evidence, in particular with regard to the inclusion of two additional categories of equipment in the scope of RoHS – medical devices and control instruments.
The EC asks for studies and evaluations that will permit the commission to analyze the full costs or benefits of provisions and potential changes in the operation of the directive. The commission also wants to know about any additional topics that should be considered. The commission, however, does not want to receive position papers.
In the review process, the commission will also investigate other hazardous substances or materials used in electrical and electronic equipment. The commission and look at how those substances and materials are managed and whether they have a negative impact on the environment or human health.
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.
