What is the Full form of PCB?
The full form of PCB is Printed Circuit Board. PCBs are an electrical circuit constructed by a non-conductive material in the way of a thin board which entirely holds copper circuits such as plastics, fibreglass, fibreglass, composite epoxy, and so on. To connect various components, such as a transistor, resistors, IC (integrated circuits), and so on, it has conductive paths written on it. It offers mechanical support & a route for the current flow to its electronic parts.
PCBs have been used in all electronic & computing gadgets, like network cards, motherboards, graphics cards & internal hard drive circuit boards, including TV, digital cameras, laptops, mobile phones, and so on.
A brief history of PCB
- In 1936, Paul Eisler, an Austrian engineer, invented the printed circuit that was part of a radio set while he worked in the United Kingdom.
- They were later used by the United States in the 2nd World War to build proximity fuzes. The USA published the invention for commercial purposes after the 2nd World War.
- Year on year, they are updated and today they are found in several electronic pieces of equipment.
Features of PCB
- Its hall wall technology reinforces its potential
- Its surface mounted technology reduces the components and assembles them on both sides of the board.
- Its foundation or base are made of tough quality
- They consist of several layers and have their features for each layer.
Benefits of PCB
The advantages of the Printed Circuit Board are listed below.
- Avoids short circuits and tight connexions
- Low Noise in Electronics.
- Less expense.
- Simple repairs & diagnostics
- Increased span of life.
- The complexity of high circuits and Reliability.
Limitations of PCB
The disadvantages of Printed Circuit Board are listed below.
- For Fine Pitch, not great
- Thermal Shock Strike
- Few PCB surfaces are costly.
