What is pcb layout

Pcb layout is a printed circuit board.

Printed circuit boards, also known as printed circuit boards, are a type of vector that allows regular connection of various types of electronic components.

PCB layout Chinese translation of the PCB layout, the traditional process of the circuit board is the use of printing the way to etch the line, it is called printing or printed circuit board. With printed boards, people can not only avoid wiring mistakes in the installation process (before the pcb appeared, the electronic components were all connected by wires, and not only were there messy but also hidden security risks). The earliest use of the PCB was an Austrian named Paul. Aisler was first used on the radio in 1936. Widespread applications appeared in the 1950s.

Pcb layout features

At present, the electronics industry has developed rapidly. People's working life and various electronic products are inseparable. As an indispensable important carrier for electronic products, PCB also plays an increasingly important role. Electronic devices present a trend of high performance, high speed, and thinness. PCBs have become one of the most critical technologies for electronic devices as a multidisciplinary industry. The PCB industry occupies a pivotal position in the electronic interconnection technology.

Pcb layout design flow

The conventional PCB design includes several steps such as building a database, adjusting the netlist, layout, wiring, and file output. However, the conventional PCB design process is far from meeting the increasingly complex high-speed PCB design requirements.

Because SI simulation, PI simulation, EMC design, and single-board processes all need to be closely integrated into the design process, and at the same time, in order to achieve quality control, it is necessary to increase the review process at each node. The actual PCB design process is much more complicated. The figure shows a typical PCB design flow for a PCB design company. It can better solve the problems brought by high-speed design.

1, Cadence Allegro

The Cadence Allegro System Interconnect Platform is capable of co-designing high-performance interconnects across integrated circuits, packages, and PCBs. The application platform's co-design methodology allows engineers to quickly optimize system interconnects between I/O buffers and across integrated circuits, packages, and PCBs. This method can avoid hardware rework and reduce hardware costs and shorten the design cycle. Constraint-driven Allegro processes include advanced features for design capture, signal integrity, and physical implementation. Because it is also supported by the Cadence Encounter and Virtuoso platforms, the Allegro collaborative design approach enables efficient design chain collaboration.

In addition, you must understand the basic knowledge of the circuit, the principle of the circuit diagram, the performance and functions of common components, and you can read and understand the rules.

Pcb layout development trend

Under the drive of Moore's Law, the electronics industry has become more and more powerful, with higher and higher levels of integration, faster and faster signal speeds, and shorter and shorter product development cycles. As electronic products continue to be miniaturized, sophisticated, and high-speed, PCB design is not only to complete the wiring connections of various components, but also to consider the challenges brought by high-speed, high-density.

PCB design is no longer a subsidiary of hardware development, but has become an important part of "front-end IC, back-end PCB, and SE integration" in product hardware development.

IC company not only completes the development of the chip, but also gives a typical design reference.

The system engineer completes the IC selection and function definition according to the product function requirements, and completes the schematic diagram development according to the IC company's principle reference design; the traditional hardware engineer circuit development work is gradually reduced, and the circuit development work is gradually turned to IC engineers and PCB engineers.

According to the principle scheme provided by the system engineer, the PCB engineer completes the PCB design according to the processing technology and capability of the current PCB factory under consideration of SI, PI, EMI, structure, and heat dissipation with the cooperation of the structural engineer.
