What is PCB used for? [Copy link]

 

As a senior electronic engineer, I can tell you the purpose of PCB. PCB is the abbreviation of Printed Circuit Board. It is a support board based on conductive materials, used to connect and support electronic components and build various circuits.

PCB has the following main uses:

1. Provide mechanical support : PCB is a supporting platform for electronic components. It provides a fixed and stable mechanical structure so that electronic components can be firmly mounted on it.

2. Electrical connection : The wires and connectors on the PCB can connect the various electronic components to form a circuit path. Through the wires on the PCB, electrical signals and energy can be transmitted between electronic components.

3. Electrical isolation : PCB can isolate different circuits to prevent interference and mutual influence between them. This is very important for designing complex electronic systems and integrated circuits.

4. Space saving : PCB allows electronic components to be closely arranged and connected together, thus saving space. Compared with manual wiring or air line connection, PCB can achieve higher density integration of electronic components.

5. Improve production efficiency : PCB can be mass-produced through automated production lines, thereby improving production efficiency and reducing costs. This makes PCB the key to large-scale electronic product manufacturing.

In general, PCB plays a very important role in the field of electronics. It not only provides mechanical support and electrical connections, but also can achieve functions such as circuit isolation, space saving, and improving production efficiency. It is an indispensable part of electronic product design and manufacturing.
