There are many aspects of PCB design that need to take into account the safe spacing. It is classified into two categories: one is electrical related safety spacing and the other is non-electrical related safety spacing.
It is best not to use electrolytic capacitors, electrolytic capacitors are two layers of thin film rolled up, this rolled up structure at high frequency performance as inductance, the best use of bile capacitors or polycarbonate gestation capacitors.
In the actual design, the frequency, power rate and gain should be considered comprehensively to decide whether to add shielding plate.
The diode junction capacitance forms high-frequency attenuation oscillation, and the equivalent series inductance of the filter capacitor weakens the function of the filter.
The configuration of decoupling capacitance can suppress the noise caused by load changes, which is a common practice in the reliability design of printed circuit boards.
PCB ink quality is excellent, in principle can not be separated from the combination of the above major components. Ink quality is excellent, is the formula of science, advanced and environmental protection of the comprehensive embodiment.
This paper introduces various techniques of the three types of interconnect design, including device installation methods, wiring isolation and measures to reduce lead inductance.
In order to alleviate this design pressure, communication chip manufacturers have to choose to develop higher speed IC products to meet the needs of large capacity and small volume products.
The production process of high frequency and high speed PCB board is basically the same as that of ordinary PCB board.
The reasonable selection of printed board size can make full use of the intermediate layer to set the shield, realize the nearby grounding better, reduce the parasitic inductance and shorten the transmission length of the signal.
A standard PCB looks something like this. Bare Board (with no parts attached) is also often referred to as a "Printed Wiring Board (PWB)".
The development level of printed circuit board industry can reflect the development speed and technical level of electronic industry in a country or region to some extent.
