The single-sided printed circuit board is usually a single-sided copper-clad laminate, and the single-sided board has only one side of the circuit (the circuit layer is on one side, and the plug-in parts are on the other side).
Double-sided printed circuit boards are usually made of double-sided copper-clad laminates, with two-layer circuit patterns of Component Side and Solder Side. During the processing of the printed circuit board, the hole walls of the vias are electroplated with copper layers to make the upper and lower layers. Conduction, through the conductive hole through communication.
The multi-layer PCB is based on the double-sided board with the addition of the internal power layer and the ground layer. Power and ground nets are primarily routed on the power plane. A multi-layer board consists of at least three circuit layers or more circuit layers, each substrate layer on the PCB is conductive through vias, and the boards are bonded together using a lamination process, and each There is an insulating material between each circuit layer.
Therefore, the design of multi-layer PCB boards is basically the same as that of double-sided boards. The key is how to optimize the routing of the internal electrical layers to make the routing of the circuit board more reasonable. Multifunctional to develop large-capacity and small-volume products.
With the continuous development of electronic technology and the wide application of large-scale integrated circuits, multilayer PCBs are developing rapidly in the direction of high-density and high-precision digitization. More and more fine line width and line spacing and micro aperture penetration and blind buried via hole, HDI technology to meet market demand.
