Problems solved by technology

For example, in the case where the electronic component is an LED package, when the LED package is fixed obliquely, the LED package is misaligned with respect to another component such as a light guide plate, so that the brightness becomes uneven, thereby causing the display deterioration of quality

Embodiment Construction

[0032] Exemplary embodiments of the present invention will be described more fully hereinafter with reference to the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0033] In the drawings, the thickness of layers, films, panels, regions, etc., may be exaggerated for clarity. Throughout the specification, the same reference numerals may denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present.

[0034] A circuit board according to an exemplary embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] will refer to figure 1 A circuit board according to an exemplary embo...

Abstract

Provided are a circuit board, and a method of mounting an electronic component on the circuit board. The circuit board according to an exemplary embodiment of the present invention includes: a pad pattern including a basic pattern and one or more additional patterns connected to the basic pattern, in which the basic pattern includes a region in which a connection terminal of an electronic component is attached by solder, the one or more additional patterns include regions in which the connection terminal of the electronic component is not attached, and the basic pattern includes an exposed side or an exposed point capable of limiting a mounting position so as to prevent the electronic component from exceeding an alignment margin.

Description

technical field [0001] The present invention relates to a circuit board, and more particularly, to a circuit board and a method for mounting electronic components on the circuit board. Background technique [0002] An electronic device such as a display device includes a plurality of electronic components such as transistors, diodes, resistors, and IC chips. Generally, electronic components may be mounted on various circuit boards such as printed circuit boards by methods such as soldering. A printed circuit board is formed by printing a circuit pattern on an insulating substrate with a conductive material such as copper. The circuit patterns include connection patterns for connecting external electronic components. [0003] Electronic components can be mounted on circuit boards by surface mount technology (SMT) which is a form of soldering. Surface mount technology involves connecting a lead frame of an electronic component to a pad of a circuit board by printing solder ...
