As of June 1, 2009, all European Union suppliers are required to comply with a raft of substance restrictions under the REACH regulation. According to an article in PCB007, the substance restrictions apply every time an article is supplied, including components, sub-assemblies and finished equipment. Enforcement action can be taken at any point in the supply chain. The substances restrictions also apply to distributors who resell components and sub-assemblies, and retailers who resell finished equipment.
The 53 substance restrictions are detailed in Annex XVII of the REACH regulation (as amended) and cover a very wide range of applications. In addition to substances already restricted under RoHS, there are an additional 19 REACH substances that can be relevant to electrical and electronic equipment and hardware products.
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.
