Printed circuit board PCB, also known as printed circuit board PWB, PCB is a relatively broad name.
pcb: printed circuit board
pwb: printed wire board
A typical PCB is actually a bare board or bare board. The reason why it is called a light board is because there are no electronic components soldered on the board.
Printed circuit boards are often referred to as motherboards because PCBs can be used as carriers for soldering various electronic components. Almost every electronic device is inseparable from the PCB, because the PCB provides mechanical support for the fixed assembly of various electronic components, and realizes the required electrical characteristics through the layout of the PCB's wiring. The manufacturing quality of PCB directly affects the stability and service life of electronic products, and affects the overall competitiveness of system products, so it is known as the "mother of electronic products", referred to as the motherboard.
PCB is an indispensable component of electronic terminal equipment, so the development level of PCB industry to a certain extent reflects the speed and technical level of the development of electronic information industry in a country or region.
The above is a brief introduction of what PCB, I hope it will be helpful to you.
The following are several different types of PCBs from the network**, and the classification of PCBs will continue to be shared in the future, please stay tuned
