How to Master Fast PCB Design Skills in PCB Design

The design of printed circuit board is based on the circuit schematic diagram to realize the functions required by the circuit designer. The design of printed circuit board mainly refers to layout design, which needs to consider the layout of external connections. The optimal layout of internal electronic components, the optimal layout of metal wiring and through-hole, electromagnetic protection, heat dissipation and other factors. Excellent layout design can save production costs and achieve good circuit performance and heat dissipation. Simple layout design can be realized by hand, while complex layout design needs to be realized by computer aided design (CAD)

1、 Organize demand

At the beginning of the design, the whole project should be planned and the circuit design should be carried out according to the requirements. With the target circuit board as the core, the input and output signals are sorted out. Be sure to understand what signals, how many circuits, details of external power supply, use environment, etc. are available. If it is powered by lithium battery, the standby time should also be considered, so the low power consumption design must be used.

2、 Modular design

Modular design, divide the circuit into several parts according to certain criteria, and carry out block design. This is particularly important in complex circuits. Most circuits can be divided into two parts: power supply and functional circuit. According to the signal type, it can be divided into digital signal and analog signal. According to the function, it can be divided into camera, communication, voice, acquisition, pulse output, etc.

3、 Prepare schematic package and pcb package

Preparing complete schematic diagrams and PCB packaging files in advance can save a lot of PCB design time, which requires the accumulation of previous projects. If there is no encapsulation, you can also download the completed encapsulation from the website that the supplier wants or responds to.

4、 Analog circuit

In the design process, if you have uncertain circuits, you can consider using simulation software to simulate local circuits. Especially for some analog circuits, the feasibility of the scheme can be verified in the simulation software. If your test environment is good, you can also consider building circuits

5、 Recommended circuit

For some ICs or MCUs that you have not used, you can take a look at the recommended circuits in the datasheet. If there is no recommended circuit, you can also go online to find out if there is any information about this chip circuit. You must be careful when reading datasheets, especially when it comes to analog circuits. You need to filter the power supply, isolate the ground, and so on.

Conclusion: This is all about fast PCB design. PCB design is a profession that has become more popular with more years of experience, because the longer the time, the richer the experience, and the stronger the ability to solve problems. If you are a relevant practitioner, it is recommended that you take more notes or records at ordinary times. I work in a PCB design company.
