Question

What's this black material?? ​

Answer 1

The insulating fibreglass board now has a pattern of copper tracks on each side that will form the circuit's interconnections. This assembly is called a core. However, motherboards have a multilayer construction, which means they have more than two copper layers.

Answer 2

A British company has produced a "strange, alien" material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the "super black" coating made of carbon nanotubes – each 10,000 times thinner than a human hair – is an odd experience
