based on many years' working experience, I give some suggestions and opinions to electronic enthusiasts. Every word is original. I respect the author.
1 What is the prospect of the electronic industry? How much is the profit of the products? Is it suitable for starting a business?
The electronic industry is generally moving forward, but the market is saturated. Just like our class entered the electronic industry for 81%, it can persist for 21% for several years, and finally less than 5% is left. Why is this happening because of the industry? Winning by quantity, high-end teamwork, technical division of labor, high product difficulty coefficient, and no advantage over traditional industries such as medical care, sales, hairdressing, catering, and supermarkets. Electronic products can't be consumed in time for a long time, and the profit of electronic products is not high, generally 5%-31%, which is similar to that of supermarkets. However, supermarket customers spend in time and have good continuity, catering can be around 51%, and the profit of medical industry can reach 111 at the beginning. You don't need too many theories to make a profit of more than 211%, so people don't want to choose the electronics industry. Look at the single-chip microcomputer development board of Taobao, and you will feel that technology is not valued. The price of the resource-rich development board on Taobao is about 56 yuan, and the price is more than 111, including ADC,DAC and digital tube driver chips. How do you think this price is wrong? < P > Take 2118 as an example, the market price of haircuts ranges from 21 to 51 yuan. This is still a casual haircut, not a haircut. If you sell an electronic product for 111 yuan, it will cost you about the same as a haircut profit. Moreover, if you are in the early stage of your business, you will use an electronic product for several years, and you will have to cut your hair every month. If you are in the early stage of your business, you may face a backlog of inventory and unsalable products, so the market cycle is too long. Even if you are creative, it will only be short-lived, because someone will copy you soon. Then it will be a price war.
Entrepreneurship with long return period of electronic products, large investment in venture capital and little capital is only suitable for industries that get quick results and consume in time.
2 Learn how difficult the electronic industry is, how much knowledge it involves, and how long it will take to become a great god.
Analog, digital, single-chip microcomputer, ARM,DSP,FPGA
analog, diode, triode, resistor and capacitor, operational amplifier circuit. Multi-state gate
single-chip microcomputer, eight-bit single-chip microcomputer, sixteen-bit
ARM 32-bit processor, upper operating system
DSP focusing on calculation
FPGA programmable logic hardware
It is impossible to know everything, two ways, high-end operating system
low-end direct operation register, it is not a day or two to become a great god skillfully, and electronics involve a wide range, many circuits, and memory response. What to learn directly to make money, and how old you can be? Can the online single-chip microcomputer development board be used in practical application?
The salary of junior level is not high 3,111 to 5,111, and the number of senior engineers is small. The salary of Beishangguang is higher, and the consumption level is also high.
More than ten years' experience tells me that unless the electronics industry is successful, it will be a hard journey, and many people will be dismissed at the age of 35. For example, Huawei has married as an old employee. On the grounds that your body can't keep up with the development intensity
You should either go on with strong perseverance or find another job
People have limited energy and are down-to-earth. Of course, it's not easy to do a good job in any industry at present
However, the electronic development industry involves too much, and the logic is too strong. A piece of code can lead to problems
Interest and hobby motivation can't always exist, and many ideas will change with time < Pay attention to sales, and think that technology can be bought with money. Engineers are craftsmen, and the market is the key, which leads to fewer people doing technology.
On the whole, technology can't make a fortune, but at most it can maintain a stable life. People who want to make a fortune should learn social common skills and interpersonal communication.
If you decide to take the road of electronic engineers, don't expect the Great God to take you, because the Great God is very busy, and you are not in the same position as him. The question you asked is too simple, and I don't want to tell you. All the knowledge has my own efforts to study
Remember that the medical and sales social service industries are lower than you at first, and then they will rise faster than you
How to judge whether your level has reached an advanced level, and make a project by yourself, from hardware to software, and transfer 11,111 lines of code, which shows that your logical thinking is very strong. Even if the enterprise is unwilling to pay you a high salary, it is not your problem
It's impossible to develop, because the actual development is multi-task execution at the same time, and the delay function can't be used, which is inefficient. < P > If you are in the electronics industry, forget I said anything. If you just have an idea or try your attitude, you should seriously consider what I said.
