Designing and Recycling Electrical and Electronic Equipment conference
The 5th ERA conference on Designing and Recycling Electrical and Electronic Equipment was held in London on 2nd and 3rd December. It is now clear that the WEEE and RoHS directives will be adopted and there were many papers discussing how government, manufacturers and recyclers will implement them. A review of the conference is published in RE⁴view or you can obtain the proceedings.

6th European Passive Components "CARTS" conference, Nice October 2002.

Dr. Paul Goodman from ERA's Reliability and Failure Analysis group presented a paper entitled "The RoHS Directive and Impact of Lead-free Solders on Passive Components". Lead-free soldering is a serious concern to passive component producers and users because lead-free solders have different properties to traditional lead-containing solders. In particular, they have higher melting temperatures. These differences affect how the solders are used and can impact on product reliability.

For assistance with changing production to lead-free solders or implementing the WEEE and RoHS directives, consult Paul Goodman +44 (0)1372 367221

IEEE advanced technology workshop on reliability

A paper on the impact of gaseous sulphides on electronics reliability was presented at this workshop on 25 November. For further information on this topic, please see the featured article.

Impact of gaseous sulphides on electronics reliability

Hydrogen sulphide and other gaseous sulphides represent a threat to electronic component reliability at very low concentrations, where it cannot be detected by odour and is difficult to measure quantitatively. Sources may be environmental or from within the structure or packaging of the device. Copper and silver are particularly at risk from sulphide corrosion.

Electric contacts and connectors - a comprehensive design and users guides

Contacts and connectors include switch and relay contacts, plug and socket connectors, crimp connections and circuit breakers. They are used to make electrical connections from a few micro-volts and micro-amps up to thousands of volts and amps, with numbers of operations varying from a few to 109. This report discusses the physics of electric contact and optimal choice of materials.
