What are the steps in circuit board design?

Circuit board design usually includes the following steps:

Determine the specifications and objectives: clarify the functional requirements of the circuit board, including the required components, interfaces, size, weight, etc..

Prepare schematic diagrams: Use circuit design software to draw circuit schematic diagrams to clarify the connection relationship and functional role of each component.

Design Printed Circuit Board: According to the schematic diagram, use the software to generate the layout of the printed circuit board (PCB), and clarify the layout and connection of each component.

Audit and Simulation: Check whether the designed circuit board meets the design specifications, and verify whether the circuit functions correctly through simulation tests.

Board making and testing: The designed circuit board is handed over to the manufacturer for production and actual testing to verify whether the function and performance of the circuit board meet the design requirements.

Optimisation and Improvement: Based on the test results, the board is optimised and improved to enhance performance and stability.

Documentation: Prepare design documentation for the circuit board, recording component layout, alignment, interface definition, etc.

Sample Making and Confirmation: Make samples of the circuit boards for practical application testing and confirmation, so that they can be finally put into production.
