After the layout of the RF PCB board components is basically completed, Printed Circuit Board Re-wiring should be started. The basic principle of rewiring is: when the assembly density permits, try to use low-density wiring PCB layout design, and the signal traces should be as thick and consistent as possible, which is beneficial to impedance matching.
For RF circuit board layout reverse engineering, the unreasonable design of the direction, width, and spacing of signal lines may cause cross-interference between signal transmission lines;
In addition, the system power supply itself also has noise interference, so it must be considered comprehensively when designing the RF circuit PCB, and reasonable wiring.
When rewiring electronic pcb board, all traces should be far away from the border of PCB board (about 2 mm), so as to avoid disconnection or hidden danger of electronic PCB card remanufacturing.
The power line should be as wide as possible to reduce the loop resistance, and at the same time, the direction of the power line and the ground line should be consistent with the direction of data transmission to improve the anti-interference ability. The signal lines should be as short as possible, and the number of vias should be reduced as much as possible;
The shorter the connection between the components, the better, to reduce the distribution parameters and electromagnetic interference between each other; for incompatible signal lines, try to stay away from each other as much as possible, and try to avoid parallel routing, and the signal lines on both sides should be perpendicular to each other: when wiring, the corner should be 135. The angle is appropriate, avoid turning right angles.
