Printed Circuit Board Design Guide 2021

Printed circuit boards or PCBs are currently a known name to all. Especially anyone who has a keen interest in electronics certainly knows what they are and their significance. But do you have in-depth knowledge about their designs? Anyone who is not a part of the PCB industry does not know the details, but having an overall idea helps a lot. Reading this will fetch you a decent idea of how the boards get designed and the systematic approach the service providers follow.


Key step – Determining the needs

Before getting into the details and technicalities of how the boards get designed, address the basics. Why do you require making the PCB? There should be a prime idea behind its making, right? Understanding the key idea is the first step, followed by the PCB design services. Consulting with the client and engineers to develop the motive of the design falls under this step. In this step, the needs of the project get cleared and create a base for the further process.

Step two – Cracking the schematic design

What is the schematic design? It is nothing but the blueprint for the manufacturers. Leading PCB design services like the GREATPCB SMT LIMITED pays major attention to this step as it determines the ultimate functionality of the PCB. Other than the overall functionality, the schematics also confirm the design traits and component placement on the board. Every essential facet related to the board hardware is crucial in this step.

  • Panel size: Determining the size of the panel to make it compatible with the equipment is a practical approach. With the successful implementation of this step, there is minimal wastage of space in the latter designing steps.
  • Correct grid: Grid spacing is another practical factor that can resolve spacing limitations. Selecting the right grid makes it compatible with other associated components.
  • Design rule check(DRC): Implementing DRC software runs assure flawlessness. In this step, the experts can eliminate the minor flaws in design and improvise it to make the unit workable. It saves time for the latter stages and proves cost-effective.

Step three – Bill of materials

Engineers develop BOM or bill of materials after confirming schematic design. The experts check the specifications and features to finalize the essential components for the project completion. They choose it by fitting the schematic design into budget lines and size parameters.


Step four – Placing them rightly

After zeroing on the components, the next part is to place them right. Every component has a specific and unique space allotment on the board to ensure workability. Finding the right placement junctures is a very tricky part. The right order that the engineers follow is –

  • Connectors
  • Power circuits
  • Sensitive and precision circuits
  • Critical circuit components
  • Rest of the components

Step five – The routing factor

Placing the components does not involve making connections. In the routing step, the engineers establish the connections so that they can work as a whole. The routing step requires a separate design approach to ensure the accuracy of working. The prime factors here are –

  • Power levels
  • Signal noise sensitivity
  • Signal noise generation
  • Routing capability and feasibility

Step six – Checking the overall design

The end step of the design has to be evaluation! Without checking the unit properly, you cannot be so sure about the overall working. It is certainly the most crucial step of all. It checks for the potential existing problems and defect and sends them for correction.


Find a service that covers it all diligently
