The design of PCBs has its own standards and consists of several successive stages:
Study of the customer's technical specification (basic wiring diagram, operating parameters required, recommendations for basic and finishing materials, a list of structural elements);
Creating a list (library) of PCB's components and seats;
Preliminary layout, placement and fixation of the board elements (creation of a 3D model of the product);
PCB routing with a set number of layers, finishing layout, routing, optimized connections and calculated resistances;
Simulation of the board with analysis of thermal load, SI, PI and EMC;
Verification with duplicate control of technical accuracy and errors of the project.
After completing the entire cycle of work, the design of the printed circuit board with a package of design documentation is delivered to the customer.
