Materials science. Electronics without lead.
In conventional consumer electronics such as cell phones, lead-containing interconnects provide the conductive path between different circuit elements. Environmental concerns have led to a search for lead-free alternatives. In their Perspective, Li et al. review these efforts, which have focused on lead-free alloys and electrically conductive adhesives. Both of these approaches are showing promise, but no one lead-free interconnect material can serve as a substitute for the conventional tin-lead solder in all devices.
