The full name of pcb is "Printed Circuit Board", which means printed circuit board. It is an important electronic component and a support for electronic components. It is mainly produced by electronic printing.

　　Printed circuit boards have certainly occupied a position of absolute control in the electronics industry. After the electronic equipment adopts the printed board, due to the consistency of the same type of printed board, the error of manual wiring is avoided, and the automatic insertion or mounting of electronic components, automatic soldering, and automatic detection can be realized, which ensures the quality of the electronic equipment. Improve labor productivity, reduce costs, and facilitate maintenance.

　　Printed boards have developed from single-layer to double-sided, multi-layer and flexible, and still maintain their respective development trends. Due to the continuous development in the direction of high precision, high density and high reliability, continuous reduction in size, cost reduction and performance improvement, the printed board still maintains a strong vitality in the development of electronic equipment in the future.

　　In which areas are PCBs used?

　　The full name of PCB in English is "printed circuit board", which is translated as "printed circuit board"

　　PCBs are used in electronic circuits in equipment to provide mechanical support and conductive paths for various electronic components. It is made by combining sheets of different non-conductive materials, such as fiberglass or plastic, to easily hold copper circuits. PCB is also known as Printed Wiring Board (PWB) or Etched Wiring Board (EWB).

　　A PCB works on a copper film/component/circuit placed inside it to provide a path for current flow. PCBs can hold a variety of electronic components that can be soldered without the use of visible wires.

　　1. What fields are PCBs used for?

　　PCBs are found in almost all electronic and computing devices, including motherboards, network cards and graphics cards, as well as hard drives and various household appliances.

　　2. Classification of PCBs

　　PCBs can be single-layer or multi-layer. In a single-layer PCB, all circuits and components are on the same surface. On the other hand, in a multilayer PCB, non-conductive (substrate) layers alternate with conductive circuits, creating a sort of sandwich effect.

　　PCBs used for very simple jobs (such as light switch panels) are typically single-layered, while PCBs used in complex work environments such as computers are multi-layered.

　　In addition, PCB is also divided into rigid and flexible. For example, in the current mobile phone, in order to make the LCD module and the battery fit better, the PCB in the middle of them is generally flexible.

　　Summary: Xiaobai Hardware Science: What does PCB mean?

　　Simply put, a PCB is a piece of non-conductive material that houses electronic components. This sheet is usually made of fiberglass or plastic and is "printed" or "etched" with the circuit, hence the name "circuit board". Copper circuits on a PCB connect electrical components, passing electrical signals back and forth.
