Abstract

See full text

A circuit board, with inbuilt protection against incoming and outgoing electromagnetic interference (EMI), includes an insulating adhesive portion, a first signal line, and a second signal line. The first signal line and the second signal line are surrounded and separated by an electromagnetic shielding film against EMI. The insulating adhesive portion fills a gap between the first signal line and the electromagnetic shielding film and a gap between the second signal line and the electromagnetic shielding film. External interference with signals in the circuit board is reduced, mutual interference between the first signal line and the second signal line is reduced, and electromagnetic radiation of the circuit board is also reduced. A method for manufacturing the circuit board is also disclosed.
