What Are The Key Functions of PCB Board 1
The PCB is made up of various components and complex technologies, with single-layer, double-layer, and multi-layer structures each requiring different production methods. It includes pads, vias, mounting holes, wires, connectors, filling, and electrical boundaries, each with specific functions. The three common layer structures are single-layer, double-layer, and multi-layer boards, with multiple working layers and connections through vias in the latter.
