Abstract
The article surveys current state of the art and challenges in the
development of the electrical contact materials in the light of the EU
Directive on Restriction of Hazardous Substances (RoHS). The focus was placed
on widely used silver-cadmium alloys. According to this directive, as of July
1, 2006, use of six hazardous materials, including cadmium, are restricted
for applicable electrical and electronic products intended for the EU market.
In contrast, traditionally preferred material for production of electrical
contacts is Ag-CdO, due to its outstanding functional properties. These
conflicting interests result in present state where RoHS directive has not
yet been implemented in its original form and has undergone numerous
amendments and exceptions regarding the use of cadmium. Main reason for this
seems to be the unrealistic time frame imposed by legislation. Although,
significant effort has been put into research and development of alternative
materials, there are still cases where adequate replacement materials had not
been found. Therefore, importance of synchronicity between legislation and
technological progress i.e. communication between legislative administration
and industry and academia is brought to light as well as some common issues
that may arise with an introduction of new replacement materials or product
modification.
