The European Union is considering new exemptions to RoHS. Some industry engineers want solder exempted. Yes, you read that correctly. Solder.
John Burke, the maverick engineer who launched the PushBack website, challenges the science in RoHS laws. So he has called for an exemption to solder on the basis that the lead-free alternatives to solder are more dangerous to the environment that the small amount of lead contained in conventional solder. You’ll find a more thorough discussion on Burke’s argument in our article, “Pushback: Where’s the science in RoHS.”
Burke submitted his exemption request to the European Commission members decided to consider the request.
Burke is looking for notes and letters of support for his proposed exemption. You can sign up at PushBack. He hopes to gather 1,000 letters of support to turn over to the European Union by the January 10 deadline for comments.
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.
