A circuit board arrangement includes a circuit board having two conductive material structures and a separating layer, where the structures are placed on opposite sides of the layer and the layer comprises includes a first graphene island stretching between a first area of a first of the structures and a second area of a second of the structures, which first graphene island is controllable to electrically interconnect the two areas or separate the two areas from each other. A method of communicating between a first and a second circuit via the structures comprises includes controlling the first graphene island to electrically interconnect the first and the second area and the first circuit communicating with the second circuit after the interconnection.
A circuit board arrangement comprising a circuit board, the circuit board comprising at least two conductive material structures and a separating layer, where the two conductive material structures are placed on opposite sides of the separating layer, said separating layer comprising a first graphene island stretching between a first area of a first of the conductive material structures and a second area of a second of the conductive material structures, said first graphene island being controllable to electrically interconnect the two areas or separate the two areas from each other, wherein the first graphene island is a controllable via running through the separating layer.
