Electronic device contg. multi-layer printed circuit board

Abstract

The invention relates to an electronic device containing a plurality of printed circuit board layers, wherein a printed circuit board arrangement (10) is assembled from two stacked printed circuit boards (11a, 11b) separated by a gap (12). The connector (14) is arranged on the lower printed circuit board (11a). A through hole (15) is formed in the upper printed circuit board opposite the connector (14). The wire (16) passes through the through hole (15) and is connected to the connector (14).

Description

technical field [0001] The present invention relates to a printed circuit board assembly mounted in, for example, an electronic equipment housing, and an electronic equipment comprising a plurality of printed circuit boards stacked on top of each other and assembled in the housing. Background technique [0002] It is known that small-sized electronic devices are superior in portability, such as notebook-sized personal computers (notebook-sized PCs). In the housing of electronic equipment, batteries and electronic circuits are assembled, and printed circuit boards with a large number of electronic components are assembled in high density. [0003] Usually, two or three printed circuit boards are stacked on each other to form a printed circuit board assembly, and the space occupied by the printed circuit boards should be set as small as possible to miniaturize the electronic equipment. [0004] However, if Figure 4 As shown, in a conventional printed circuit board assembly f...

Problems solved by technology

[0005] Therefore, there is a problem that the space occupied by the printed circuit board assembly becomes larger and the size of the electronic device becomes larger

[0006] In addition, in order to facilitate the connection operation of the connector 4, it is necessary to arrange the connector 4 near the edge of the printed circuit board 1a, and there is a difficulty that the mounting position of the connector 4 and the electronic component 3 is limited.

[0007] Moreover, since the wire 5 needs to continue along the upper surface of the printed circuit board 1a with the electronic components 3 mounted thereon, the assembly wiring diagram of other electronic components arranged on the path of the wire 5 is unfavorably limited.

[0008] In addition, in the manufacturing process of the printed circuit board assembly, after the wire 5 is connected to the connector 4 of the printed circuit board 1a, another printed circuit board 1b needs to be attached, and another difficulty is that the assembly sequence is also limited.
