How far has RoHS come?

Posted: 01 Oct 2007 ?? ?Print Version ?Bookmark and Share

Keywords:EU RoHS compliance? NWML RoHS implementation? RoHS WEEE scope changes?

The RoHS legislation's existence is unknown to most consumers, but it has had a huge effect on the electronics industry. The directive is being "policed" by an increasing number of EU RoHS enforcement bodies. The United Kingdom's enforcers, National Weights and Measure Laboratory (NWML), started work a year in advance, while other member states' bodies have only started work more recently.

Two approaches to enforcement are being used: by audit of documentation and selective analysis of purchased products. Some states' customs are also checking imports. NWML's experience shows that 90 percent of products are not fully compliant, most of them having one or two components with a restricted substance. Re-work of Pb-free soldered products is a particularly common problem. The use of obsolete components having Sn/Pb termination coatings and screws with hexavalent chromium passivation coatings are other common causes of non-compliance.
