The power input end of the printed circuit board is connected to the electrolytic capacitor of about 100uF. If the volume allows, the capacitance is larger than that. 2. In principle, a 0.01uF chip capacitor should be placed next to each IC chip. If the gap of the circuit board copy board is too small to be placed, a tantalum capacitor of 1 ~ 10 can be placed every 10 chips or so. 3. For components with weak anti-interference ability and large current variation when switched off and memory components such as RAM and ROM, decoupling capacitors should be connected between the power line (Vcc) and ground. 4. The lead of the capacitor should not be too long, especially for the high-frequency bypass capacitor.

In terms of the layout of components, the components that are related to each other should be placed as close as possible. For example, the clock generator, crystal oscillator and the clock input end of the CPU are all prone to noise, so they should be placed close to each other. For those easy to produce noise devices, small current circuit, large current circuit switching circuit, etc., should try to make it far away from the MCU logic control circuit and memory circuit (ROM, RAM), if possible, these circuits can be made into circuit boards, so that is conducive to anti-interference, improve the reliability of the circuit work.
