Description

[TECHNICAL FIELD] The disclosure relates to an electronic device including a printed circuit board. [Background Art] The remarkable development of information and communication technology and semiconductor technology has rapidly increased the proliferation and use of various electronic devices. Electronic devices have been developed in recent years so that communication may be performed while the electronic devices are being carried. An electronic device may refer to a device that executes a specific function according to a loaded program, such as a home appliance, an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/audio device, a desktop/laptop computer, or a vehicle navigation device. For example, these electronic devices may output stored information as sound or an image. As the integration level of electronic devices increases and high-speed, large-capacity wireless communication becomes more common, a single electronic device such as a mobile communication terminal may be equipped with a various functions.
