    Abstract: An electronic device according to an embodiment may include: a Printed Circuit Board (PCB) including a first face and a second face; a semiconductor chip mounted on the second face; a conductive pad disposed on the second face; a solder resist layer disposed on the second face and including an aperture; an arc-shaped opening having an inner diameter and an outer diameter, disposed along an outer periphery of the conductive pad and in the aperture; and at least one external terminal disposed on the semiconductor chip and bonded to the conductive pad. The conductive pad may include: a first region having a smaller diameter than the outer diameter; and at least one second region extending from the first region in a first outer circumferential direction, and located at least in part between both ends of the opening. In addition, various embodiments recognized through the specification may also be possible.
