Evolution of Multilayer PCBsThe concept of PCBs dates back to the early 20th century, but it wasn’t until the 1960s that multilayer PCBs began to gain traction. The need for more complex and reliable electronic circuits drove the development of PCBs with multiple layers. These multilayer PCBs consist of several layers of conductive material separated by insulating layers, allowing for more intricate and compact designs.
Structure of Multilayer PCBsA multilayer PCB typically consists of three or more layers of conductive material, such as copper, laminated together with insulating materials like fiberglass or epoxy. The layers are interconnected through vias, which are small holes drilled through the board and filled with conductive material. This structure allows for a higher density of components and connections, enabling more complex circuitry in a smaller footprint.
