The creation of a printed circuit board design consists of seven main stages. Let's look at each in more detail:
Optimization of wiring and silkscreen printing
Preparing a library of components and schemas. Preparing a separate package for components of a specific board.
Depending on the product purpose, its dimensions and type, a frame with outlined holes for future fasteners is created. The production requirements for the components placement should also be considered.
The responsible stage of design is the choice of the design layout. At this stage, all components of the future board are assembled and arranged on the substrate. They are chosen depending on the requirements and purposes of the project. It is important to arrange everything taking into account all the requirements and characteristics of materials. This is especially important when manufacturing high-speed boards, where the wiring diagram and each component affect the final impedance of the board.
Contacting the PCB manufacturer
This needs to be done before the PCB design project is completed. After that, the latest edits are made in cooperation with the PCB manufacturer that you plan to order the PCBs from.
DRC and structure control
It is difficult to complete this stage without the involvement of specialists, since it requires tests and checking whether all components are located correctly and whether there are any errors in the calculations.
