Circuit board with rigid portion and flexible portion having connecting end and electronic package using the same

A circuit board, comprising:

• a rigid board body, comprising a plurality of conductive layers and a plurality of dielectric layers located between the conductive layers;
• at least one bendable extension portion, wherein each of the at least one extension portion is connected to a side of the rigid board body and is formed by a plurality of layers of the conductive layers and at least one layer of the dielectric layers extending outside the rigid board body, and an end of each of the at least one extension portion is a connecting end;
• a plurality of connecting members, arranged on a surface of the connecting end and electrically connected to a signal layer of the conductive layers;
• and
• a plurality of shielding members, arranged on the surface of the connecting end and electrically connected to a ground layer of the conductive layers, wherein each of the shielding members is arranged around the corresponding connecting member, the connecting members and the shielding members protrude from the surface of the connecting end, and a height of the shielding members is lower than a height of the connecting members,
• wherein the at least one extension portion comprises two extension portions on a same side of the rigid board body, surfaces of connecting ends of the two extension portions are arranged opposite to each other to form a jack of a connector, and the connecting members and the shielding members are located in the jack.
