Abstract
In this paper we consider the complexity problem in electronics production process. Particularly, we investigate the ways to reduce sensitivity of transmission line characteristics to their parameter variations. The reduction is shown for the per‐unit‐length delay and characteristic impedance of several modifications of microstrip transmission lines. It can be obtained by means of making an optimal choice of parameter values, enabling proper electric field redistribution in the air and the substrate. To achieve this aim we used an effective simulation technique and software tools. Taken together, for the first time, they have allowed formulating general approach which is relevant to solve a wide range of similar tasks.
Highlights
Electronics is more and more widely used in human life
Complexity of electronics is continuously increasing. It results in increasing the number of electronics parameters
The aim of this paper is to propose a general approach to solving the complexity problem in electronics production process based on the summary of the recent studies devoted to minimizing the sensitivity of microstrip-like lines characteristics to variations of their parameters
Summary
It results in increasing the number of electronics parameters. To treat the problem we can consider two main parts of the problem: concerning electronic components and supporting structures for their packaging. As for components, their nomenclature is very wide. The most popular structure is a PCB, while an IC and a chip can be considered as dedicated to electronic components, especially due to the recent trends of system-in-package (SiP) and system-on-chip (SoC) designs. One can see that a PCB line impedance value, for example, calculated as 55 Ω can really be 45 Ω or 65 Ω. Proper tools for multiple, but quick and accurate, calculations of the characteristics are necessary
