Printed Circuit Board (PCB) is an indispensable basic component in all electronic devices and is known as the “mother of all electronic products”. Through the conductive wiring on the PCB, different electronic components can be tightly integrated to accomplish the tasks of signal transmission and power supply, thus realizing the overall function of the device. Nowadays, PCBs are widely used in information technology, communication equipment, consumer electronics, automotive electronics, aerospace and military, precision instruments and various industrial equipment.
The main flow of PCB layout design is as follows:
◕ Component Construction
Although the company already has a complete component database, brand new parts often need to be imported into new projects. Engineers need to build components according to MTK part specifications and original factory datasheets, and then conduct rigorous audits after building, and finally incorporated into the system database for subsequent use.
◕ Pre-design planning and communication
Before entering the design stage, we need to fully communicate with the system analysis (SA), research and development (RD) and hardware engineering (HW) teams. Discussions include design criteria, PCB materials and processes, mechanism configurations, critical signal paths, impedance design, and functional verification requirements.
◕ Component Placement and Preliminary Design
The first step in circuit design begins with component placement, which directly affects subsequent routing, heat dissipation, and overall performance. This stage requires consideration of various factors such as high-frequency interference, electromagnetic compatibility, and mechanical constraints, and is a critical step in ensuring design quality.
◕ Circuit Wiring Design
After completing the component placement, the wiring work begins. Special signals (e.g., high-speed data lines, high-frequency lines) are prioritized and special attention is paid to line width, line spacing, and alignment length, which are usually required to be less than 0.1mm to ensure signal integrity and transmission efficiency. In addition, power supply and general signal routing are also designed according to standardized sequences. For high-end designs, simulations and optimizations are performed in collaboration with the high-frequency and EMC teams to achieve the goals of low interference, low latency, and impedance consistency.
◕ After the final review and output of the manufacturing data
circuit layout is completed, we work with the SA, RD, and HW teams again to confirm that the functionality is fully compliant with the original design intent. Then, we follow the MTK specification to ensure that all the design details are up to standard, and finally export the layout file in the manufacturer’s specified format to formally complete the entire PCB design process.
