Difference between single-layer PCB and double-layer PCB

This article provides a detailed comparison of single-layer and double-layer PCBs, covering key differences in material structure, manufacturing processes, design considerations, and typical applications. Single-layer PCBs use a single-sided copper foil structure, offering low cost but limited design flexibility, while double-layer PCBs feature dual conductive layers and plated through-holes, supporting more complex circuits at a higher cost.
