In the realm of PCBA products for communication, high-precision circuit layout is achieved through advanced software to optimize circuit design, which shortens signal transmission paths, minimizes circuit crossovers and electromagnetic interference, and enhances signal transmission efficiency and stability. Meanwhile, high-frequency and high-speed materials with low dielectric constant (Dk) and low dielectric loss (Df) are typically employed to effectively reduce signal attenuation and distortion during transmission. Additionally, signal integrity design incorporates advanced design and simulation technologies: during the design phase, simulation software is utilized to analyze the signal transmission process, proactively predict and address potential issues like signal distortion, reflection, and crosstalk.
