Radio frequency and band-shaped wire interface assembly method

Abstract

The invention discloses a radio frequency and band-shaped wire interface assembly method, which is high in transmission efficiency, small in loss, reliable in performance and high in integration interconnection density. The radio frequency and band shape wire interface assembly method can be realized through steps of integrating a high frequency signal member and a low frequency member through a broadband microwave backboard to form a motherboard, and placing a high frequency connector and an LAM connector on a same plane of a same plane layer, expanding into a stack of layers of a three-dimensional circuit toward a z direction through interlayer vertical interconnection by the planar circuit printed with the circuit graphs, in a radio frequency portion, adopting signals between Rogers RO6002 core board layers and performing radio frequency connection through metalized hole interconnection structure between the stack layers of the core plates, realizing signal transmission between the radio frequency layers through the layer pressure, realizing electric communication by a high frequency connector 2 and a high frequency connector 5 through a surface welding disc of a broadband microwave backboard 1 and manufacturing a three-dimensional non-interfering high density circuit through a corresponding prepreg sheet lamination layer.

Description

technical field [0001] The invention relates to an assembly method for transmitting a high-speed and high-frequency signal interface using a strip line. Background technique [0002] Against the background of scientific and technological progress and huge market demand, communication technology is developing rapidly, from single function to multi-functional integration, from low frequency band to high frequency band, from single frequency band to multi-band comprehensive application, gradually covering Civilian and military equipment; due to the development of communication functions in the direction of diversification, integration, high frequency band, and high speed, this further increases the requirements for information transmission and communication. At present, the traditional network construction method of transmitting high-frequency and high-speed signals through physical connections formed by high-frequency cables can no longer meet the needs of communication networ...

The shortcomings of this document are that it is limited to theoretical analysis, it is impossible to know the design method of theory and objects, and it does not have the realizability of a complete function.

This paper introduces the basic characteristics of high-frequency substrate materials and three kinds of high-frequency substrate physical properties, analyzes the way to avoid the transmission effect of high-speed circuits, summarizes the key points of wiring design of high-speed printed circuit boards, and puts forward wiring improvement actions and preventive measures. The insufficiency of the literature is that it only summarizes from the perspective of production, does not combine design with production, and does not design high-speed signal interface design, which has no reference value for interface design

Introduced the basic theory of signal integrity and the signal integrity simulation process based on the simulation software Hyperlynx, focused on how to use the high-speed PCB design method to ensure the signal integrity of the high-speed data acquisition module, and analyzed the circuit board designed under this method IBIS model simulation was carried out for the key network of the project. The shortcoming of this document is that it is not systematic. It only briefly describes it from the perspective of wiring. It does not give a complete design method combined with a product object, and there is no description of the input and output interface design. Achievability without a complete function

[0006] All in all, traditional high-frequency cables transmit high-frequency and high-speed signals. Under the conditions of modern communication signals, it is required to meet the requirements of small size and light weight of equipment. How to realize multiple high-frequency and high-speed signals in a limited space The interconnection of communication equipment ensures the long-term, reliable and high-performance work of communication equipment. At present, there is no definite technical solution
