What does PCB board mean? These definitions are easy to confuse
Many people have heard of PCB boards, but they don't know what PCB boards mean, and they may even confuse the definition of some names.
PCB board refers to a printed circuit board, which is a provider of electrical interconnection of electronic components. But it is not a general terminal product. Some people will confuse the motherboard in a personal computer with a circuit board. However, it is not the case. The motherboard is accurately called the motherboard. Although there is a circuit board in the motherboard, it is by definition They are different. In the evaluation, it can be said that the two are related but not the same. For example, an IC board with integrated circuit components mounted on a circuit board, although it is also related to the circuit board, cannot be called a PCB board directly.
PCB board The PCB board we often say is exactly a circuit board without any components on it, also called a bare board. Divided into: single-sided, double-sided, four-layer and higher-layer multi-layer PCB boards.
Let me introduce to you the structure of the PCB board:
Circuit and drawing surface: The circuit is used as a tool for the conduction between the originals. In the design, a large copper surface will be designed as a grounding and power layer. The route and the drawing are made at the same time.
Dielectric layer: also called the substrate, it is used to maintain the insulation between the circuit and each layer.
Hole: The function of the via hole is to allow the circuits of more than two layers to be connected to each other, the larger hole is used as a part plug-in, and some non-through holes (nPTH) are generally used for surface mount positioning and assembly When fixing screws are used.
The above is some simple knowledge of PCB board compiled by the editor, of course, there is more than that. If you are interested, you can look at the introduction of PCB board related knowledge on Baidu.
