Hongtai tells you, why are people in these developed countries so keen on mobile payment as a convenient payment method? Because in their view, the "cashless era" with full coverage of mobile payments hides the danger of many dark waves.
In the past, the panel was hailed as a sunset industry by the outside world. In this regard, International Data Information Corporation (IDC) said that it is still very optimistic about the development of the panel industry.
The term "plug hole" is not a new term for the printed circuit board industry.
The following five aspects are introduced to you: 1. Brief introduction of circuit board 2. Introduction of circuit board base materil 3. Basic stack structure of circuit board 4. Circuit board production process
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.
