No PCB, no electronics, a little advice for electronics beginners
Summary of content: 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, and medical treatment. Equipment, defense, aerospace and other fields are indispensable electronic components in modern electronic information products.
PCB has been invented in the mid-1930s for more than 80 years. History shows that there is no circuit board, no electronic circuit, flight, transportation, atomic energy, computers, aerospace, communications, home appliances ... all of this cannot be achieved.
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 in 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 PCBs is self-evident. For students who want to learn or are learning PCB or electronics, we have a few suggestions:
1. Have confidence in yourself
We don't have to exceed anyone, but we can set our goal to exceed ourselves. This is the easiest way to cultivate our self-confidence. It is also the most effective way to achieve sustainable development. We can also get a lot of unexpected gains. Letting you be less competitive and competitive will also allow you to learn more at ease, and will also make you more happy. As time goes by, you can feel your progress, never doubt yourself, Just do it!
2, see more information on application circuit design
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 knock this bone down. If you want to communicate with practice as quickly as possible, read more magazines and books on electronic design. Although it is difficult to start, it is definitely the most effective and the longest. You can understand a lot of new technologies, and for you in the future It helps to understand and learn new things.
3. Learn professional courses
If you are a student studying electronics at school, you must learn professional courses and lay a solid foundation. Some seemingly unused courses may be encountered at work someday. Remember, don't memorize, you must understand thoroughly.
4. The foundation of analogue electricity should be laid
Many new products are experiencing problems with analog electronics. Although many people will pass on the full replacement of analog power, in fact, engineers who have really done electronics development will probably realize that any stable electronic product cannot be separated from the analog power! At the very least, it must have a power supply. A reasonable power supply design must have at least filtering, anti-interference, and EMI compliance ... Digital circuits must also have signal lines. The anti-interference and signal impedance matching of signals are also analog. In fact, the problem of analogue electronics is often the most difficult and time-consuming to solve.
5.You can make some simple circuits by yourself
Many company bosses have a headache, and the fresh students they recruit will not use EDA software, and even more than half of the fresh students will not know a few of the large electronic components. How can people spend money to hire people, and people who start a company just want to earn a few dollars ... In fact, we can spend some money to make simple circuits. The simplest is to spend dozens of dollars to make a timer board, or to make a power amplifier, which is dozens of dollars. When I look for a job, I bring two or three boards made by myself, which is definitely better than a printed resume. EDA software recommends learning Orcad, Allegro, etc.
6.Deep into a certain industry
If you have a certain foundation in PCB design or other electronics fields, I suggest you go into a certain industry. Computers, automobiles, home appliances, communications, industry, transportation, aviation, multimedia audio and video, medical, power, and microelectronics. Each industry is intelligent, networked, wireless, and miniaturized. There are many high-end and extremely profitable companies in every industry. Focus on an industry for several years and master the core technology of the industry, your future will be broader.
