PCB basic design process
prepare the component library of schematic SCH and the component library of PCB. Component library can use protel (many electronic veteran birds have protel at that time

Zheng Zhenyu 51 development board PCB real combat fast
The design of printed circuit board mainly refers to the layout design, which needs to consider the layout of external connections.
The surface treatment technology of PCB board and its advantages and disadvantages and application scenarios
The circuit board inside the line is mainly pure copper, that is, bare copper plate. Some people think that the gold color is copper, which is the protective layer on the copper.
Harm of PCB warping
On the automatic plug-in line, if the PCB is not smooth, it will cause inaccurate positioning, and the components cannot be inserted into the holes of the board and the surface mounting pad, and even crash the automatic plug-in machine.
The analog signal wiring area is distributed on both sides of the PCB board
provides circuit board design services, circuit board design education consulting, PCB quick proofing, small and medium-sized batch circuit board production and manufacturing services,
Pcb transmission line
For integrated circuits, due to the increase in edge speed, if no other measures, the length of the line is greatly shortened to maintain the integrity of the signal.
High frequency PCB board
Transmission delays on ground and interconnect lines in high-speed systems are also factors to be considered in system design.
Wiring arrangement and reasonable layout of the components of Fanyi PCB dispatched field engineers
In mixed-signal PCB design, there are special requirements for power wiring and the isolation of analog and digital noise from each other to avoid noise coupling, thus increasing the complexity of layout and wiring.
PCB design and production company multi-layer pcb circuit board proofing production process
PCB board is printed with solder paste, installed with electronic components, and then fixed by reflow welding.
PCB power supply system design
The Bonding line, C4 bump and solder ball connect the chip, package and PCB together. The whole power supply system should ensure that each integrated circuit device provides stable voltage within the normal range.
About the PCB design of the board and matters needing attention
Another technique is to lay a ground wire between the two lines. The ground wire is low impedance, and adding such another wire will weaken the electric field that causes the interference!
Component placement strategy in multilayer PCB system
There is a limit to how many circuits you can fit on a board. PCBS themselves have a size upper limit for manufacturing equipment and standard panel size reasons.
