Abstract: An electronic device having a substrate includes a substrate and at least one outer layer. The substrate has a plurality of first vias. The outer layer has a plurality of second vias. The outer layer is disposed on a side of the substrate. The first vias have a larger distribution density or quantity than the second vias so that a portion of the first vias are electrically connected to the second vias, and a portion of the first vias are electrically floating.

Abstract: A circuit board and an electronic package using the same are provided. The circuit board includes a rigid board body, at least one bendable extension portion, connecting members, and shielding members. The rigid board body includes conductive layers and dielectric layers therebetween. The extension portion is connected to a side of the rigid board body and formed by layers of the conductive layers and at least one layer of the dielectric layers extending outside the rigid board body. The connecting members are arranged on a connecting end of the extension portion and electrically connected to a signal layer of the conductive layers. The shielding members are arranged around the corresponding connecting members and electrically connected to a ground layer of the conductive layers. The connecting members and the shielding members protrude from the connecting end. A height of the shielding members is lower than a height of the connecting members.
