In High Speed Circuit Board Layout Scheme Cloning, decoupling capacitors play an important role, and its placement location is also very important, since it will greatly improve the performance of printed circuit board after copy its gerber file.

This is because when the power supply provide power charge to the load for a short period of time, the stored charge in the capacitor can prevent the voltage from falling. If the capacitor is placed in an improper position, the line impedance may be too large and affect the power supply.

At the same time, the capacitor can filter out high-frequency noise during high-speed switching of the device. Regarding the placement of decoupling capacitors, we know that improper placement will increase line impedance, reduce its resonance frequency and affect power supply. Small value capacitors have a short decoupling path, so they are generally placed close to the IC, otherwise the decoupling effect will not be achieved; large value capacitors have a long decoupling path and relatively loose placement. Therefore, the input power generally passes through a large capacitor first, then a small capacitor, and then enters the IC chip.
