  Principles of anti-interference design for printed circuit boards Layout of power cord: 1. According to the current size, try to widen the wire routing as much as possible. 2. The direction of power and ground wires should be consistent with the direction of data transmission. 3. A decoupling capacitor of 10-100 μ F should be connected to the power input terminal of the printed circuit board. Layout of secondary ground wire: 1. Separate digital from analog. 2. The grounding wire should be thickened as much as possible, and at least 3 times the allowable current on the printed board should be passed, generally up to 2-3mm. 3. The grounding wire should form a dead loop as much as possible, which can reduce the potential difference of the grounding wire. Three decoupling capacitor configuration: 1. The input end of the printed circuit board power supply is connected to an electrolytic capacitor with a temperature of 10-100 μ F. It would be even better if it could be greater than 100...
