Now only the reduced noise suppression is expressed:
It is well known to add decoupling capacitors between power and ground.
Try to widen the width of the power and ground wires, preferably the ground wire is wider than the power wire. 0.05～0.07mm, power cord is 1.2～2.5mm
For the PCB of the digital circuit, a wide ground wire can be used to form a loop, that is, a ground net can be used (the ground of the analog circuit cannot be used in this way)
Use a large-area copper layer as a ground wire, and connect the unused places on the printed board to the ground as a ground wire. Or make a multi-layer board, power supply, ground wire each occupy one layer.
