A printed circuit board, in which two or more copper clad laminates (CCLs) are laminated vertically from an uppermost circuit layer to a lowermost circuit layer, includes a non-destructive testing area, mislamination identifying portions in the non-destructive testing area, the mislamination identifying portions being in the CCLs, respectively, through-via holes vertically exposing the mislamination identifying portions, respectively, in the non-destructive testing area, the through-via holes being spaced apart from each other by a first interval, and a probe via extending vertically and being in contact with an end portion of each of the mislamination identifying portions on a same side. A length of the mislamination identifying portion in an N-th (N is an integer of 1 to K) layer CCL in a horizontal direction is longer than a length of the mislamination identifying positioned in an (N−1)-th layer CCL in the horizontal direction.

An electronic device is provided, including a housing, a side member, a display, a printed circuit board (PCB), and a communication device. The housing includes a first plate facing a first direction and a second plate facing a second direction opposite to the first direction, forming a space between the first and second plates. The side member surrounds at least part of the space. The communication device is disposed in the housing and connected with the PCB. The side member includes a first antenna unit disposed on one side of the electronic device, electrically connected with a radio frequency (RF) module, and having a first metal frame. The housing further includes a board-type antenna which includes a second antenna unit electrically connected with a WiFi module, an antenna connector configured to electrically connect the first and second antenna units, and a third antenna unit electrically connected with the antenna connector.

The present invention provides a mobile terminal and a control method using an intuitive gesture as an input to perform a function. Specifically, the present invention provides a mobile terminal including a sensing unit for sensing movement of the mobile terminal, a wireless communication unit for transmitting/receiving a radio signal to/from an external terminal and a control unit for sensing a distance from the mobile terminal to the external terminal based on the strength of the received radio signal, and performing a specific function when the sensed movement corresponds to specific movement and the sensed distance is within a specific range.
