China Multilayer Fr-4 Blind Buried Hole Immersion Gold HDI PCB/Circuit Board PCB

China Multilayer Fr-4 Blind Buried Hole Immersion Gold HDI PCB/Circuit Board PCB

The first step is to get a PCB; it records the models, parameters, and position of all the elements on the paper, especially the diode, the direction of the three tubes, and the direction of the IC gap. It is best to take two photos of the location of the element with a digital camera.

PCB Knowledge:

The copper clad reduces the heating surface of copper and plays the role of electromagnetic shielding. But it should be pointed out that the grid is made up of interlaced lines, and we know that for circuits, the width of the wiring has a corresponding "electrical length" to the circuit board's working frequency, when the working frequency is not very high. Perhaps the effect of grid lines is not obvious, once the electrical length and frequency match, it is very bad. You will find that the circuit is simply not working properly and signals are being transmitted everywhere to interfere with the system's work. Therefore, for the use of the grid, it is suggested that the design of the circuit board can be selected according to the working situation.(multilayer pcb)
