Understand the design requirements and develop a PCB board redesign plan
1. Read the schematic diagram carefully and understand the working conditions of the circuit.
Factors related to wiring requirements such as the operating frequency of analog circuits and the operating speed of digital circuits. Understand the basic function of the circuit, the role in the system and other related issues.
2. On the basis of full communication with the schematic designer, confirm the key networks on the board, such as power supply, clock, high-speed bus, etc., and understand their wiring requirements. Understand the high-speed devices on the board and their wiring requirements.
3. According to the requirements of the “Hardware Schematic Design Specification”, conduct a normative review of the extracted PCB schematic.
4. For the parts in the schematic diagram that do not conform to the hardware schematic design specifications, it is necessary to clearly point out and actively assist the schematic designer to modify it.
5. Develop a single board PCB design plan based on the communication with the schematic designer, fill in the design record form, and the plan should include schematic input, layout completion, wiring completion, signal integrity analysis, and light drawing completion during the design process Time requirements for waiting for key checkpoints. The design plan should be signed and approved by both the PCB designer and the schematic designer.
6. When necessary, the design plan should be approved by the superior
