PCB boards are laminated layers of conductors and insulators. They provide a base for electronic components, allowing them to work together and provide the desired outcome. Instead of wires, there are traces of copper etched on the surface to let current travel from one point to another. The components can be placed anywhere on the board with designers usually aiming for the smallest footprint possible. Wired circuits have mostly given way to PCBs over the years because of the latter’s multiple advantages:
1. Reproducibility
PCBs are now easier to design thanks to computer software. Once a layout has been completed, the file can simply be sent to a manufacturer for creation of the physical circuit. All of the parameters are there so making it should be a breeze. If there is a need to produce another batch, then they can open up the same file and do it all over again with the exact same results. The file may even be sent to another manufacturer without any issues. As long as they follow the specifications, the new boards will function in the same way as the old ones.
2. Consistency
Wiring often requires manual labor. When you introduce human intervention, you also create space of variability. Even experienced workers can make errors or provide inconsistent results. Even small deviations from the norm can lead to unexpected consequences such as circuit noise and the like. With PCB boards, everything is incredibly precise. Manual creation is possible but machines usually take over to ensure the consistency of trace widths, component placement, label printing, and so on. This lessens the likelihood of errors.
3. Density
The components have been shrinking as engineers find ways to pack more transistors into smaller packages. Individual capacitors, resistors, inductors, and diodes are also getting tinier. It would be difficult to use wires to connect these because of their size. They are more suited to being soldered into a board and connected via flat copper traces on the surface. With PCB design, components can be arranged densely in any given area. This leads to the further miniaturization of devices which consumers appreciate.
4. Economy
Since manufacturing is mechanized, it is easier to scale up or down depending on the need. This makes PCB boards more economical for companies that have to produce the circuits on a massive scale. Instead of hiring more workers and training them, they can simply make the machines run longer and ensure a steady supply of materials. Small businesses can take advantage of this as well since they can outsource the production to PCB manufacturers even for small orders at reasonable costs.
5. Repairability
PCB boards look much cleaner without so many wiring crowding the surface. Since the traces are clearly visible with their orderly lines on the surface, it is easier to test them for quality control before they are sent out into the world. Errors can be found more readily with this process usually automated as well. High-speed cameras are used for inspection to find manufacturing defects and increase confidence in the outputs.
