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!
The crystal oscillator, as we often say, is the quartz crystal oscillator and the quartz crystal resonator.
Generally speaking, many engineers pay more attention to forward crosstalk, but this is the wrong thinking.
Isolation - Ensure that each circuit of power is kept power and control separate. If you must connect them together in the PCB, make sure it is as close to the end of the power path as possible.
It is essential to use high dielectric strength materials that can resist higher voltages before breakdown.
When PCB size is too large, the printed line is long, the impedance increases, the anti-noise ability decreases, and the cost increases. Too small, the heat dissipation is not good, and the adjacent lines are susceptible to interference.
The role of PCB board is not only to combine scattered components, but also to ensure the regularity of circuit design, a good way to avoid the chaos and error caused by manual wiring and wiring.
Considering the performance and processing efficiency of PCB, the preferred process sequence is as follows: 1. If the component surface is mounted on one side, it is formed by reflow welding; 2. 2. If the component surface patch and plug-in are mixed: one
The PCB process design requirements are introduced in detail: 1, test point addition, 2, optical location point, 3, add working edge, 4, film file output, 5, plate rules, 6, board information annotation
PCB design impedance matching: PCB design impedance matching refers to a suitable collocation between the signal source or transmission line and the load. According to the access mode PCB design impedance matching has serial and parallel two ways; Accordi
Preliminary work to be done before PCB design :1, determine the number of PCB layers, 2, PCB design rules and restrictions, 3, component layout
Spacing is more important in high voltage designs because the voltage across the board components makes arcing between the two conducting components more likely to occur on your PCB. Any electric arcs that do occur pose a higher risk to both the product a
