Scientists have expressed concern that removing lead from some electronic devices could lead to damaged goods. Lead has been shown to cause health problems, particularly in children. But electrical engineers have noted that low-lead solder has a tendency to grow unexplained, so-called "whiskers" of tin. These growths have at times extended out far enough to cause short circuits, ruining electronic equipment.
Last year, the European Union banned the problematic metal, along with others, from most electronic equipment to prevent it from being released to the environment through incineration and landfills. While there are exemptions allowed, manufacturers are finding it harder to find reliable materials.
