Getting to the roots of lethal hairs

Fine metal hairs, also called metal whiskers, on tin-plated copper cause short circuits in electronic components. An international team of researchers is finding out why they grow

05-Oct-2009

A short circuit can be quite hairy: satellites have failed, a NASA computer centre was repeatedly paralysed and the US public heath authority recalled thousands of pacemakers - all because tin whiskers caused a short circuit in the electronic components of these devices. A team of scientists from ...
