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.

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.
Transmission delays on ground and interconnect lines in high-speed systems are also factors to be considered in system design.
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 board is printed with solder paste, installed with electronic components, and then fixed by reflow welding.
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.
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!
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.
The rapid development of the electronics industry, the increasing demand for PCB (printed circuit board) manufacturing industry, including the rising board layer, the increasing tracking density and the thinning inner layer, all of which are leading to th
The default value is 16MB, which is defined in the network driver. The master device is responsible for allocating shared storage areas to other processors and for memory mapping.
Only when the digital signal is routed on top of the analog portion of the circuit board or the analog signal is routed on top of the digital portion of the circuit board will the interference of the digital signal to the analog signal occur.
