A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. A printed circuit board has pre-designed copper tracks on a conducting sheet. The pre-defined tracks reduce the wiring, thereby reducing the faults arising due to loose connections. One simply needs to place the components on the PCB and solder them.
- PCBs are the backbone of electronic devices.
- A PCB is a non-conductive board that holds all electronic components through a circuit embossed over it.
- PCBs are built to last for a wide range of industrial, commercial, and domestic applications.
- They can be customized to any specifications to users’ requirements.
Basic History of PCBs
- PCBs were first developed during World War II.
- The revolutionary invention was made by an Austrian engineer, Paul Eisler.
- Since 1929, PCBs have been mass produced for commercial applications.
- They were first used in transformers and capacitors.
