The term "plug hole" is not a new term for the printed circuit board industry.
A printed circuit board (PCB) is used to carry electronic components and provide a master circuit for connecting the components to the circuit. From the structural point of view, PCB is divided into single panel, double panel and multilayer board. But most people can't tell the difference, so what are the three differences?
Faced with the increasingly high integration of hardware platforms and more and more complex electronic systems, the PCB layout should have a modular thinking, which requires the use of modularity in the design of hardware schematics and PCB wiring. , Structured design method. As a hardware engineer, on the premise of understanding the overall architecture of the system, first of all, we should consciously merge modular design ideas in the schematic diagram and PCB wiring design, combined with the actual situation of the PCB, plan the basic idea of PCB layout.
Set the size of the board and frame according to the structural drawing, arrange the mounting holes, connectors and other devices that need to be positioned according to the structural elements, and give these devices non-movable attributes. Dimension the size according to the requirements of the process design specifications.
The US Government Accountability Office (GAO) released a technology assessment and analysis report entitled "5G Wireless Technology" (hereinafter "Report"), which outlines the basic situation of 5G, summarizes the opportunities that 5G can bring, and finally analyzes the United States. Challenges in deploying 5G.
