Here’s the summarized version in English: “This edited version introduces specialized PCB wiring techniques for three layout types: right-angle, differential, and serpentine routing. Right-angle routing impacts signal integrity through capacitive loads, impedance discontinuities, and EMI, critical in high-speed RF designs. Differential traces offer advantages in anti-interference capability, EMI suppression, and timing precision, crucial for low-amplitude signal circuits like LVDS. Serpentine traces adjust delays but require careful handling to minimize crosstalk and timing issues in high-speed designs.”
