Abstract

A flexible printed circuit board comprises: a power wiring layer that transmits power; and a signal wiring layer that is insulated and stacked on the lower portion or the upper portion of the power wiring layer.

Description

technical field [0001] The present invention relates to a flexible printed circuit board (FPCB). In particular, the present invention relates to an FPCB capable of minimizing line loss and signal interference in a high frequency or ultra high frequency communication environment. Background technique [0002] Information processing devices such as smartphones, PDAs, and tablets receive text, graphics, and the like using various input devices such as keyboards and mice. [0003] Due to the rapid development of the information society, the range of use of information processing equipment is expanding. Following this trend, existing keyboards and mice for input have limitations in satisfying users' needs. Therefore, the demand for an input device that is easy to use and has less erroneous operations is increasing. [0004] A touch panel can be installed on the display surface of a display device such as an electronic notepad, LCD (Liquid Crystal Display), PDP (Plasma Display ...
