The first stage: scheme design The engineer plans the basic modules of the circuit and draws the circuit diagram of the product according to the circuit site situation, market research or product innovation needs. This stage can be done without altium design software. Manuscripts and other office software generally meet the requirements. The following stages need to be applied to the altium design software.
The second stage: Schematic design According to the product circuit frame diagram, the specific schematic diagram is drawn to make the circuit system specific. The design at this stage will determine the circuit structure and the layout scale of the PCB board design.
The third stage: export the component netlist information to the pcb board design After drawing the schematic diagram, it is necessary to transfer the component package and component connection information to the pcb board design environment. The current adware can directly send the component netlist and component package information to the pcb board design environment with just one command, and has seamless docking and bidirectional synchronization functions.
The fourth stage: component layout After the component packaging is transferred to the pcb board design environment, it is necessary to carry out components according to the product's chassis shape, panel structure, electromagnetic compatibility specifications, reasonable requirements for electrical layout, and pcb board design stack structure. layout.
The fifth stage: pcb board design wiring After the components are laid out, the pre-drawn lines generated according to the netlist in the pcb board design are filled with solid lines. This filling line is a copper foil line on the finished circuit board, and the rationality of the circuit board wiring will directly affect the quality of the circuit board.
The sixth stage: computer-aided manufacturing processing and manufacturing Electronic engineers are required to output GERBER files for processing and manufacturing.
