PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is a bridge that carries electronic components and connects circuits. As the "mother of electronic products", it is widely used in communications, consumer electronics, and computers. , automotive electronics, industrial control, medical equipment, national defense and aerospace and other fields, are indispensable electronic components in modern electronic information products.

　　It has been more than 80 years since PCB was invented in the mid-1930s. History shows that without circuit boards, without electronic circuits, 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, and semiconductor technology reflects a country's industrial modernization level and guides the development of the electronic information industry. The electrical interconnection and assembly of semiconductors (integrated circuits, ICs) must rely on PCBs.

　　It can be seen that there is no PCB and 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 suggestion:

　　1. Have confidence in yourself

　　We don’t have to say that we have to surpass anyone, but we can set the goal to surpass ourselves and make a little progress every day. This is the easiest way to cultivate our self-confidence, and it is also the most effective way to achieve sustainable development, and we can also get a lot of unexpected gains. It will make you less competitive, and it will also make you study more at ease, and it will also make you more happy. You can feel your progress over time, never doubt yourself, Just do it!

　　2. Take professional courses

　　If you are a student who is studying electronics in school, you must learn professional courses well and lay a solid foundation. Some seemingly useless courses may be encountered at work one day. Remember, don't memorize by rote, you must understand thoroughly.

　　3. The foundation of die and electricity should be laid well

　　The problems encountered by many new products now are die-electric problems. Although many people say that digital power will completely replace mold power, in fact, engineers who have actually done electronic development will probably know that any stable electronic product cannot be separated from mold power! At least there must be a power supply, a reasonable power supply design At least there must be filtering, anti-interference, and qualified EMI... Digital circuits must also have signal lines. Signal anti-interference and signal impedance matching are also analog and electrical... In fact, analog and electrical problems are often difficult to solve. The biggest and the most time consuming.

　　4. See more information on application circuit design

　　Although it may be difficult at the beginning, don't think that you are too stupid. Others can learn it because he is determined to take the time to gnaw this bone down. If you want to communicate with practice as quickly as possible, you should read more magazines and books on electronic design. Although it is difficult to start, it is definitely the most effective and the longest. Understanding and learning new things helps.

　　5. You can make some simple circuits at your own expense

　　Many company bosses have a headache. The fresh graduates they recruit do not know how to use EDA software, and even more than half of the fresh graduates don’t even know a few electronic components from DouDa. How can people spend money to hire people, people just want to make a few dollars to open a company... In fact, we can spend some money to make some simple circuits. The simplest is to spend dozens of dollars to make a timer board, or to make a power amplifier, which is tens of dollars. When looking for a job, carrying two or three boards made by yourself 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 certain foundation in PCB design or other electronic fields, it is recommended that you go deep into a certain industry. Computers, automobiles, home appliances, communications, industry, transportation, aviation, multimedia audio and video, medical, power supplies, and microelectronics are all in the process of intelligence, networking, wireless, and miniaturization. There are many high-end and extremely profitable companies in every industry. If you focus on an industry for a few years and master the core technology of the industry, your future will be brighter.
