An electronic device may include: a flexible printed circuit board having a flexible region and a support region and configured to be deformable in the flexible region; an antenna module facing the support region of the flexible printed circuit board; a solder ball for connecting the antenna module to the flexible printed circuit board; an underfill resin filled between the flexible printed circuit board and the antenna module in a liquid state and then solidified; and a solder wall for connecting the antenna module to the flexible printed circuit board and placed between the solder ball and the flexible region to block the flow of the underfill from the support region toward the flexible region before the underfill resin is solidified, and the solder wall has a width equal to or greater than the width of the flexible region. Various other embodiments are possible.

Electronic device comprising solder wall

An electronic device and an operation method thereof are provided. The electronic device includes a connecting unit configured to connect to an external power supply device that provides power to the electronic device; a first power managing unit configured to drive the electronic device using power provided from a first external power supply device connected to the connecting unit; a second power managing unit configured to charge a battery contained in the electronic device using power provided from a second external power supply device connected to the connecting unit; and a switching module configured to connect the connecting unit to one of the first power managing unit and the second power managing unit. Also, connection pins are not configured redundantly and respectively for external power supply devices, but a connecting unit is unified through a single common wiring and is commonly used, and thus, a wiring and components for supplying power may be reduced.

Apparatus and method for managing power supplied to an electronic device

A method of controlling a clock frequency of an electronic device and an electronic device using the same is provided. The electronic device includes a check module that is configured to check a clock frequency of at least one Radio Frequency (RF) band, and a control module that is configured to shift a clock frequency of a high speed signal such that a noise generation clock frequency and the clock frequency of the at least one RF band checked by the check module are not identical, when an interface of the high speed signal is used.

Electronic device and method of controlling clock frequency of electronic device

An electronic device is provided. The electronic device includes a circuit board including multiple lands arranged on a surface, and an electrical receptacle including multiple contacts electrically connected to the multiple lands, the electrical receptacle being installed on the circuit board, where at least two contacts are connected to at least one land among the multiple lands.

Electronic device including connector

A method and an apparatus perform Mobile High-definition Link (MHL) signal filtering. The method of performing the Mobile High-definition Link (MHL) signal filtering in a terminal includes determining whether a transmission device for MHL signal transmission is connected; determining whether a call continues when the transmission device is connected; and determining whether to perform the MHL signal filtering in the terminal based on whether the call continues. Accordingly, there is an advantage of improving picture quality of an image output from a multimedia device by effectively removing a common mode noise even when an RF weak electric field is formed due to call generation.
