As per the PCB GLOBAL DESIGN the basic idea of a PCB is multiple wires arranged in a manner to perform electrical connections on the board. PCB provide main role while component assembly process. PCB stands for "Printed Circuit Board" where the wires are arranged on a different type of board (material used for the board: woven glass or cotton paper and epoxy) and those wires provide an electrical connection for an electronic component. That means on a PCB there are not only wires, but there is also space for wires, electronic components, holes, vias, designators (text of the component name), etc.
The first question that comes to mind after reading the preceding paragraph is, "Why are there wires on the board if we can connect them without board?" The answer is, there are key benefits to having the wire on board, as follows:
- Reduce the complexity of a connected wire compared to a separate wired connection.
- Save space.
- Reduce errors on connections.
- Easiness of tracking errors on connections
- Open and short tests can be easily tested.
- Mechanically support electronic components and wire.
- Easy to move.
- Provide electric safety.
These are the primary advantages of PCBs, however there are other benefits as well. During PCB assembly, PCBs make it simple to add components on the board. In a subsequent blog, we'll go through each benefit of PCB in further depth.
