The lead-free material may make it easier and cheaper to make "stacked" chips with more computing power.
A new type of solder can be melted and shaped in three dimensions under the force of a weak magnetic field.
New Haven, Conn. — Yale University scientists have developed a magnetic solder that can be manipulated in three dimensions and selectively heated, and offers a more environmentally friendly alternative to today’s lead-based solders.
For decades, hydrogen has been touted as a fuel of the future, providing a cleaner, more sustainable energy source that could one day replace fossil fuels.
