Abstract
A printed circuit board includes circuit lines having different transmission characteristics. In the printed circuit board, mounted components are connected to each other at a plurality of points by an anisotropic conductive film (ACF) adhesion by using a flexible circuit board (FPC) which includes transmission lines formed of circuit line patterns having transmission characteristics optimal to signals. This structure enables the printed circuit board to be easily designed, and be also made smaller.
Claims8
A printed circuit board comprising:
- a board;
- a plurality of components mounted on the board;
- transmission lines which have different transmission characteristics, which are located between associated components included in the plurality of components to electrically connect the associated components, and which permit various kinds of signals to be transmitted through the transmission lines;
- and
- a flexible cable in which transmission lines are formed for those signals of the various kinds of signals which drive desired components included in the associated components, and cause two or more of the desired components to be electrically connected to each other by an anisotropic conductive film adhesion.
