The PCB is composed of various components and complex process technologies. The structure of a PCB circuit board can be single-layer, double-layer, or multi-layer, each with different production methods. This article will detail the component names and uses of PCB boards, production methods for each layer structure, and the main functions of different types of work levels.
Firstly, a printed circuit board consists of pads, vias, mounting holes, wires, components, connectors, filling, and electrical boundaries. The main functions of each component are as follows:
– Pad: Metal hole for soldering component pins.
– Mounting Hole: Used to secure the PCB.
– Wire: Copper film for connecting component pins.
– Connectors: Used to connect circuit boards.
– Filling: Copper coating for ground wire network, reducing impedance.
– Electrical Boundary: Limits the size of the circuit board, ensuring components fit within it.
Next, there are three common layer structures for PCBs:
(1) Single-Layer Board: Copper on one side, no copper on the other. Components are placed on the non-copper side, and the copper side is used for wiring and soldering.
(2) Double-Layer Board: Copper on both sides, known as the top and bottom layers. The top layer is for component placement, and the bottom layer is for component soldering.
(3) Multi-Layer Board: Contains multiple working layers, including the top and bottom layers and several intermediate layers. Intermediate layers can serve as wire, signal, power, and ground layers, all insulated from each other with connections through vias.
