Abstract

The invention relates to the technical field of PCBs, and discloses a PCB and a manufacturing method thereof, and the PCB comprises a mother board provided with at least one inner-layer metal pattern, and a pattern assembly provided with an outer-layer metal pattern. The mother board comprises a top wall, a bottom wall and a side wall arranged between the top wall and the bottom wall in a surrounding mode, and the inner layer metal pattern part is exposed out of the side wall; and the pattern assembly is welded on the exposed area of the inner layer metal pattern on the side wall, so that the outer layer metal pattern of the pattern assembly is electrically connected with the inner layer metal pattern of the mother board. According to the PCB provided by the invention, the space of the side wall of the mother board is utilized, the pattern assembly with the outer-layer metal pattern is arranged on the side wall, and the pattern assembly is electrically connected with the inner-layer metal pattern of the mother board, so that the signal transmission function of the pattern assembly is realized. According to the PCB, the limited space is effectively expanded, the available space is expanded, and the wiring density or the element patch density is improved, so that the PCB meets the increasingly miniaturized and high-density development trend.

Description

technical field [0001] The present invention relates to the technical field of PCB (Printed Circuit Board, printed circuit board), in particular to a PCB and a manufacturing method thereof. Background technique [0002] In printed circuit boards, the pads are mainly divided into pin pads and surface mount pads. The pin pads have solder holes and are mainly used for soldering pin components, while the surface mount pads have no solder holes and are mainly used for surface mounting. paste components. With the miniaturization of semiconductor design, the density of components on the corresponding PCB substrate is getting higher and higher, and the pad setting area on the surface of traditional PCB is becoming more and more tense. Therefore, how to increase the mounting area of ​​PCB to meet the needs of terminal electronic products The miniaturization and high-density design requirements are urgent problems to be solved at present. Contents of the invention [0003] The obj...
