PCB schematic and PCB design

time:Feb 18. 2022, 15:26:44 Views:158


 PCB schematic is a simple two-dimensional circuit design, showing the function and connectivity between different components. The PCB design is a three-dimensional layout, and the position of the components is marked after the circuit is guaranteed to work normally.

PCB schematic and PCB design(图1)

   Therefore, the PCB schematic is the first part of designing a printed circuit board. This is a graphical representation that uses agreed symbols to describe circuit connections, whether in written form or in data form. It also prompts the components to be used and how they are connected.

   As the name suggests, the PCB schematic is a plan and a blueprint. It does not indicate where the components will be specifically placed. Rather, the schematic outlines how the PCB will ultimately achieve connectivity and constitutes a key part of the planning process.

   After the blueprint is completed, the next step is the PCB design. The design is the layout or physical representation of the PCB schematic, including the layout of copper traces and holes. The PCB design shows the location of the above components and their connection to copper.

  PCB design is a stage related to performance. Engineers built real components on the basis of PCB design so that they can test whether the equipment is working properly. As we mentioned earlier, anyone should be able to understand the PCB schematic, but it is not easy to understand its function by looking at the prototype.

   After these two stages have been completed, and you are satisfied with the performance of the PCB, you need to implement it through the manufacturer.
