This application is a National Phase Entry of PCT International Application No. PCT/KR2016/006484 which was filed on Jun. 17, 2016, and claims priority to Korean Patent Application No. 10-2015-0124480, which was filed on Sep. 2, 2015, the content of each of which is incorporated herein by reference.
Various embodiments of the present invention relate to signal wiring and device arrangement on a printed circuit board.
Various tests and calibration works for radio frequency (RF) performance may be conducted to develop/mass-produce electronic devices having a network function. RF connectors may be used for product development, but may not be used for mass production. Alternatively, in the case of producing various functional products by using the same printed circuit board in common, RF connectors may or may not be used depending on product specifications. As described above, in the related art, a separate bypass route is configured for processing depending on whether RF connectors are used or not.
Accordingly, the electronic devices may require an additional space, a bypass line, and the like on a printed circuit board to configure the bypass route. Furthermore, due to the detour of signal wiring, output of a signal applied to the signal wiring may be attenuated, or it may be necessary to additionally mount a passive element to compensate for the signal attenuation.
Various embodiments provide a printed circuit board device for effectively providing signal wiring and an electronic device including the same.
An electronic device according to various embodiments of the present invention includes a housing, a printed circuit board disposed inside the housing, a communication circuit disposed on the printed circuit board, a first conductive pattern and a second conductive pattern electrically connected with the communication circuit, a conductive material electrically connected between the first conductive pattern and the second conductive pattern, a third conductive pattern spaced apart from the first conductive pattern and/or the second conductive pattern in a first direction, and a fourth conductive pattern spaced apart from the first conductive pattern and/or the second conductive pattern in a second direction opposite to the first direction. The first conductive pattern and the second conductive pattern each include a first part having a first width and a second part having a second width greater than the first width, and at least a part of the conductive material is disposed on the second part of the first conductive pattern and the second part of the second conductive pattern.
Other aspects, advantages, and salient features of the invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the present invention.
According to various embodiments of the present invention, it is possible to provide the shortest path in a signal operating process of a specified processor and to reduce the consequential signal loss.
In addition, the present invention may provide various effects derived through the present specification.
Hereinafter, various embodiments of the present invention may be described with reference to accompanying drawings. Accordingly, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the present invention. With regard to description of drawings, similar elements may be marked by similar reference numerals.
In this invention, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., elements such as numeric values, functions, operations, or components) but do not exclude presence of additional features.
In this invention, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.
The terms, such as “first”, “second”, and the like used in this invention may be used to refer to various elements regardless of the order and/or the priority and to distinguish the relevant elements from other elements, but do not limit the elements. For example, “a first user device” and “a second user device” indicate different user devices regardless of the order or priority. For example, without departing the scope of the present invention, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.
It will be understood that when an element (e.g., a first element) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element), it may be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present. In contrast, when an element (e.g., a first element) is referred to as being “directly coupled with/to” or “directly connected to” another element (e.g., a second element), it should be understood that there are no intervening element (e.g., a third element).
According to the situation, the expression “configured to” used in this invention may be used as, for example, the expression “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of”. The term “configured to” must not mean only “specifically designed to” in hardware. Instead, the expression “a device configured to” may mean that the device is “capable of” operating together with another device or other components. For example, a “processor configured to (or set to) perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which performs corresponding operations by executing one or more software programs which are stored in a memory device.
Terms used in this invention are used to describe specified embodiments and are not intended to limit the scope of the present invention. The terms of a singular form may include plural forms unless otherwise specified. All the terms used herein, which include technical or scientific terms, may have the same meaning that is generally understood by a person skilled in the art. It will be further understood that terms, which are defined in a dictionary and commonly used, should also be interpreted as is customary in the relevant related art and not in an idealized or overly formal unless expressly so defined in various embodiments of this invention. In some cases, even if terms are terms which are defined in this invention, they may not be interpreted to exclude embodiments of this invention.

According to various embodiments of the present invention, the RF connector 110 may be mounted on the connector connecting part 150 and may be electrically connected to the processor 120. For example, an antenna may be connected to the RF connector 110. According to an embodiment, the RF connector 110 may radiate an electrical signal of the processor 120 through the connected antenna or may forward an external signal received by the connected antenna to the processor 120. According to an embodiment, the RF connector 110 may be removed from the printed circuit board 102. If the RF connector 110 is removed, the connector connecting part 150 may be exposed.

According to various embodiments, as in a state <13>, the electronic device 100 may have a state in which the RF connector 110 is removed. As described in the state <11>, the electronic device 100, from which the RF connector 110 is removed, may include the printed circuit board device 160 and the housing 101, but the RF connector 110 may be excluded from the printed circuit board device 160.

In the above-described structure, a signal output from the processor 120 may be transmitted through the second pattern 153, the conductive material 159, the first pattern 151, and the contact part 130. Furthermore, a signal received by the contact part 130 may be transmitted to the processor 120 through the first pattern 151, the conductive material 159, and the second pattern 153. As illustrated in the drawing, the signal path 170 may directly connect the processor 120 and the contact part 130 to decrease an interconnection wiring loss and reduce the consequential signal distortion.
