Printed Circuit Board (PCB) is a bridge that carries electronic components and connects circuits. As the “mother of electronic products”, it is widely used in communications, consumer electronics, computers, automotive electronics, industrial control, medical devices, and defense. And aerospace and other fields, is an indispensable electronic component in modern electronic information products.
PCB has been invented for more than 80 years since the 20th century in the mid-1930s. History shows that there is no circuit board, no electronic circuits, flight, transportation, atomic energy, computers, aerospace, communications, home appliances… all this is impossible.
The reason is easy to understand: chips, ICs, and integrated circuits are the food of the electronic information industry. Semiconductor technology reflects the level of industrial modernization of a country and guides the development of the electronic information industry. The electrical interconnection and assembly of semiconductors (integrated circuits, ICs) must rely on PCBs.
Visible, no PCB, no electronics.
For electronics, the importance of PCB is self-evident. For students who want to learn or are learning PCB or electronics, we have a little advice:
1. Have confidence in yourself
We don’t have to overtake anyone, but we can set our goal to be more than ourselves, so that it is easiest to cultivate our own self-confidence. It is also the most effective way to achieve sustainable development, and we can get a lot of unexpected gains. Letting you have less eagerness to win, you will be able to learn more peace of mind, and you will be able to get more happiness. You can feel your progress after a long time, never doubt yourself, Just do it!
2, look at the application circuit design information
Although it may be difficult at first, don’t feel that you are too stupid. Others can learn because he is determined to take the time to get rid of this bone. If you want to communicate with practice the fastest, look at magazines and books on electronic design. Although it is very difficult to start, it is definitely the most effective and the longest. You can learn a lot of new technologies and you will be in the future. It will be helpful to understand and learn new things.
3. Learn professional courses
If you are a student who is going to school to study electronics, you must learn professional courses and lay a solid foundation. Some seemingly inexperienced courses may be encountered someday in the work. Remember, don’t memorize it, you must understand it thoroughly.
4, the basics of the mold should be laid
Nowadays, many new products encounter problems that are modular. Although many people will pass the digital power to replace the model power, in fact, engineers who have actually done electronic development will probably have experience, and any stable electronic product can not be separated from the mold opening! At the very least, there must be a power supply. A reasonable power supply design must have at least filtering. It must have anti-interference and EMI. The digital circuit must also have a signal line. The anti-jamming of the signal and the matching of the signal impedance are also modes. In fact, the problem of mode power is often the most difficult and time-consuming to solve.
5, you can spend some money to do some simple circuits
Many company bosses have a headache. The recruits will not use EDA software, and even more than half of the new electronic components of the new students will not know a few. How do people spend money to hire people, people open a company and want to earn a few dollars… In fact, we can spend some money to do simple circuits. The easiest way to spend tens of dollars on a board of timers, or to make a power amplifier, is tens of dollars. Looking for a job with two or three boards made by myself is definitely better than a printed resume. EDA software recommends learning Orcad, Allegro, etc.
6, go deep into a certain industry
If you have a foundation in PCB design or other electronics, it is recommended that you go deep into a certain industry. Computers, automobiles, home appliances, communications, industrial, transportation, aviation, multimedia audio and video, medical, power, microelectronics are all intelligent, networked, wireless, and miniaturized. In every industry, there are many outstanding companies that are high-end and extremely profitable. Focusing on a few years in an industry and mastering the core technologies of the industry, your future will be broader.
