AI Technical Summary

Problems solved by technology

However, the characteristic impedance of the wiring in the traditional connection board structure cannot be controlled, which will make the signal transmission discontinuous, resulting in a large insertion loss during signal transmission, and the Smith chart (also known as the Smith chart) Divergent, difficult to debug convergence

Abstract

A connection board (3), a circuit board assembly (300) and electronic equipment (100), the connection board (3) comprising a board body (31), a signal transmission part (32) and a grounding part (33). The board (31) is provided with a signal transmission hole (311) and at least one grounding hole (312), and the signal transmission hole (311) extends from one end (314) of the board (31) to the other end (314) of the board (31). 315), the signal transmission part (32) is located in the signal transmission hole (311), at least one grounding hole (312) extends from one end (314) of the board body (31) to the other end (315) of the board body (31) , and the same as the extension path of the signal transmission hole (311), at least one ground hole (312) surrounds the signal transmission hole (311) and is spaced from the signal transmission hole (311), and the ground part (33) is arranged on at least one ground hole ( 312). The above connecting plate (3) can precisely control the characteristic impedance.

Description

technical field [0001] The present application relates to the field of electronic products, in particular to a connection board, a circuit board assembly and an electronic device. Background technique [0002] With the development of technology, consumers' demand for electronic products is getting higher and higher, and R&D personnel's demand for miniaturized printed circuit board (Printed Circuit Board, PCB) design is also becoming stronger and stronger. Multilayer printed circuit board stacking design System architecture is also more popular with developers. [0003] While this printed circuit board architecture brings miniaturization benefits, it also introduces some new problems. Among these problems, how to solve the signal connection between different printed circuit boards, especially the connection of radio frequency signals, is very critical . A multilayer printed circuit board connects two printed circuit boards using a connection board in which traces are used t...
