PCB Full Form - Printed circuit boards are PCBs in their complete form . A printed circuit board, or PCB for short, serves as the structure on which an electrical circuit is built. What is a printed circuit board ( PCB )? A printed circuit board ( PCB ) is a structure for assembling electronic components and their connections into a unified circuit that allows electrical current to pass between components. The PCB baseboard is typically made of a rigid nonconductive material, although it can also be built on a flexible base or on a base made up of both rigid and flexible materials. Electronic components such as diodes, inductors and transistors attach to the circuit board ... Conclusion PCB , or Printed Circuit Board, is like the backbone of electronic devices , that holds and connects all the important parts, like resistors and chips, which allows them to communicate with each other and make the device work properly. Without a PCB , electronic gadgets like phones or computers wouldn’t function. Let’s know everything about PCM, PCB and PCMB streams so that you will not have any confusion when choosing subjects in class 11 science.
