1. Concept Design

The first step we need to determine the purpose of designing the PCB, which we call the conceptual design of the board. At this stage, we need to define what functions the PCB will have, what features it will have, the interconnection with other circuits, the approximate size, and its The location where it will be placed in the final product, and its working environment also needs to be considered, including approximate temperature, humidity, etc.

2. Draw a circuit schematic

When we finalize the final concept design, we will move on to the next stage: draw the schematic diagram of the circuit. The schematic diagram includes all the information needed for the electrical components of the circuit board to function properly, including component names, values, ratings, etc. At the same time , you should also create a Bill of Materials (brilliantly) with very detailed information such as part number, reference designator, description, quantity, package, etc., and keep these two documents updated every time you change your PCB design.

3. Create a board-level block diagram

In the third step, we need to create a board-level block diagram, which refers to a drawing that describes the precise final dimensions of the printed circuit board. Each area on the diagram should be clearly labeled as Blocks, Components, and Constraints.

4. Determine component placement

At this stage, we will decide where each component will be placed on the board. During this process, you may go through many stages of work until you make a final decision, which is quite normal. Because we need to make sure that each component is Placed in the correct location to maximize PCB quality and performance.

5. Create circuit routing

Now that the location of each component has been determined, we now need to establish circuit routing to determine the routing and routing priority of the circuit.

6. test

In the last step, we need to do a series of tests to make sure that the design can meet all our needs. If the design is well tested, then we can go to the manufacturing process, if not, we need to make adjustments based on the original PCB design.
