Here are some examples – manual welders, I have seen the so-called “strong welding apprentices with 2X experience”, and after getting in touch with them, I found…
I am a R&D staff with a salary of 10,000 yuan, and I am usually not idle. Even with a soldering iron, you can hand-solder 0.5mm pitch TQFP, DFN and other packaged ICs with just one soldering iron. In addition, I have tried hand-soldering BGA… But I have been soldering plug-ins all my life. Tell me: “Don’t use SMD in the future, it is not convenient for mass production.” I was speechless… From that day on, When I was developing all the devices, I used SMD (resistance and capacitance are always 0603 after all). A personal job like a “welder” exists for “processing”, and my design determines how the product can be used. The “labor cost of welders” is much more expensive and can be completed by just walking through the patch production line in the factory. I can negotiate directly with the factory for all “fertile details” and optimize my own based on their feedback. Design, if it’s a prototype, just do it yourself, so what’s the use of their “talent”? ! The same 3 welders, Ethiopia Sugar with 3 months/3 years/30 years of experience, also asked them to weld a row of SIP pins. Who can tell the difference? ! All I can say is – the tools for this position are too simple!
Similarly, for work such as treasury management, the company’s “full-time treasury management” mentality only stayed at – This shelf holds resistors and capacitors, that shelf holds ICs, etc… As for me, I would directly serialize all the devices and group them into the combination storage boxes, so that no matter how many devices there are, they will not be messed up, and the rest will be in that library. In my eyes, there is no difference between [MAX232CSE] and [MAX232CSE+]! ! ! I really have no concept of RoHS at all… At least my small warehouse of R&D samples is much more advanced than the old man’s.
Therefore, from the perspective of a migrant worker, I think the “difficulty” of an individual’s work is the real difference between “a good person and a bad person”! The reason why R&D is so awesome is because there are so many tools to learn (here we are referring to R&D talents in the true sense)! Without a foundation in advanced mathematics, you will not be able to learn the basics of electronics well, and naturally you will not be able to learn the underlying series of specialized research courses well.
Ethiopians Escort Nowadays, there are too many people who think they are awesome because they can program microcontrollers. Ask them if they can use it. What should I do with the knowledge I have learned about microcontrollers… The general answer is that I think 9.9 Chengdu is a “microcontroller development board”! I have been studying “delay”, “jitter elimination”, “assembly and C” all day long.”Is it better?”, “Which one is better, 51 or ARM?” and wasting time repeatedly! Treating the efforts of future generations as nothing, and constantly reinventing tires!
Ethiopians Escort I just have time to talk a few words today——
“Delay” and “anti-bounce”——delayms(X); and while(internal) are often used in the main loop of an OS product program. event); If you feel that this approach is not good, but do not know how to correct it, suggest to learn the OS practices and state machine program architecture; if you feel that this is enough and not too troublesome, then you are not worthy of doing research and development!
“Which one is better, assembly or C?” – I still hold on to the 51 assembly, and think that assembly is “fast” and “controllable”, and I believe that some unscrupulous authorities so-called “real masters are pure assembly” “, as far as the barking sound is concerned, you will always be just a “skilled worker”! In this area, except for those ultra-large quantities of low-cost 4-bit microcontrollers that require ET Escorts In addition to assembly, even AT89C2051 can be programmed in C. So C, as a “tool that is convenient for people”, is left alone and needs to be used in assembly to show that one is an expert. That is, The true portrayal of many “barking” people!
My opinion on most so-called “assembly masters” – most people have no idea about memory management and use registers absolutely. The global variables named by address renaming are used everywhere (maybe many are just temporary variables). They are said to be high efficiency and small space. The final result is that the code size and memory usage are much larger than that of the C program. Among the various modules of the program, The ultra-high coupling between spaces and the difficulty of transplantation. Then I was so proud of the assembly program I wrote for dozens of A4 sheets and felt how great I was… Finally, I encountered a problem that took me N times the programming time. .
Ethiopians Escort “Which is better, 51 or ARM” – another topic of debate, but since the current Cortex core MCU Under the low-cost offensive of ET Escorts, the balance has tilted a lot. A few years later, the debate about “Which one is better, XX or ET EscortsXX” will definitely come back again. Will develop, people who are obsessed with this problem will inevitably become “skilled workers” as they grow up (I don’t mean to be disdainful, but from the perspective of workers, everyone should be aware of the difference in income)
There is another point of view –
Those who do R&D need to work as operators for several years before they can makeGood products cannot be developed directly at once
Many small companies agree very much with this point of view, which is indeed the point they are most opposed to! At least I have been engaged in research and development since my sophomore year and have never been an operator for a day. Time for young people is also time! Many foreign companies do not have the pressure to survive. Some companies in Japan initially adopted a “lifetime contract system”. Their income would not be a penny a year at least and they would not be able to afford a bathroom!
As far as I am concerned, this may be the true portrayal of many young engineers – living with their parents, getting married, buying a house, etc. without a penny from home, and without a girlfriend.
So, what do we have? Motivation for further study! Young hard work! As the so-called “first job determines the industry”, the first few years are also the most important learning period! But this is the key point, to be an operator, haha~~ It can be said that the improvement of skills is not to advance but to retreat! “Operators can use their spare time to study” is basically a joke! At least this is the case for ET Escorts small companies in our country, so naturally after “a few years”, I really became a “research and development staff”, You’re just an assistant. How old are you at this time? Buy a house? marry? Please… Unless you have family support, the “Brother Guangbo” mentioned in my signature post is 27 years old and can’t even survive the probation period with an income of 2,000. Want to get married in Shanghai? Want to buy a house? Want a future? ? ? Haha…
My thirst for knowledge has always been very strong, so I never miss any opportunity to learn. When I need to determine the devices used in the project, I will directly run SEG and go around. Looking for “seclusion” masters, you can often learn a lot of details that you usually don’t pay attention to from those masters. It is the most basic capacitor, and there are a bunch of…ceramic, monolithic, CBB, polyester, tantalum, niobium, solid state, super, etc… And ceramics are divided into C0G, X5R, Y5V, etc… All the characteristics, manufacturers, supplies, parasitic parameters, lifespan, cost-effectiveness, etc. were all clearly understood. These are just the results of the conversation in two afternoons, and then I naturally searched onlineET Escorts The relevant information is more stable for the rational and internal affairs… The improvement in this way is much more intuitive than looking at pictures every day, Even how Murata’s EMI filter was used and the actual application results in mass products can be clearly understood… The same is true for processing. When I go to the patch processing plant to communicate related matters, I always go to someone else. Chatting with the boss… From where he came, IThey have learned a lot about manufacturing, such as how to optimize their own designs, so that they can better help detect and improve product yields, because they undertake a large number of wireless projects (the boss himself is very healthyEthiopia Sugar (a hardware engineer with 2X years of experience), I have viewed many PCBs of batch RF products, and have improved many high-frequency PCB layouts. The experience of running wires through antennas…
The more I learn, the more I feel the importance of theory, and I feel quite uncomfortable when I think of someone else’s point of view –
Practice is of no use, the most important thing is to practice it
I don’t understand why such a fallacy is accepted by so many people? ! The ego thinks – reality is the boss! This is not going from one extreme to another! If you don’t even understand the scope of the test results before implementation, and just design a design that says “this works, but I don’t understand why it works”, this is not a good project! It’s about playing art! Many people ignore reality. The fact is that they don’t understand it! Take a switching power supply transformer as an example. What do you think of a power frequency transformer? How many times do you go around the low level, how many times do you go around the secondary level and are you done? ! Copper Ethiopians Escort loss, iron loss, air gap, primary inductance, what magnetic core to use, etc. The basic situation is completely “random” Next, I randomly took the resources at hand and found out that it worked. After that, I was so happy that I used it and called it an experience! Of course, if you can’t use it, just replace Ethiopia Sugar Daddy with some resources at hand, and keep adding and subtracting until you can finally make it work. After using it, you will definitely be more ecstatic and call it a hard-won experience! Then Ethiopia Sugar Daddy then the Chinese people’s trick appeared, trying their best to keep it secret and add a sense of mystery to it, I wish I could put a seal on it and write it “Family experience”!
And the so-called “reality” itself is also the integration and sorting out of the experiences of later generationsEthiopia Sugar, which highlights its Importance!
For software, practical knowledge is equally important! Like “software engineering”, it’s also a signatureThe cupEthiopians Escort tool company mentioned in the file link, I didn’t expect BUEthiopians SugardaddyG continues to burst out, and the boss is now depressed. He has no fish to catch. He is working on DEBUG every day. A program that is not bound by standards cannot be coordinated by many people. The original intention of many engineers may be mixed with some selfishness, and they want to write a program that “only they can understand”. As a result, they use a lot of inexplicable styles and structures, which ultimately leads to a slightly larger program size, such as more than 100,000 lines. You can’t control it yourself. In a highly coupled state, the program itself is like a big coffee table. In the end, everyone’s time is wasted, and the gain and loss are equal! In addition, as mentioned below, “Which one is better, assembly or C?”, the most common mistake made by people struggling with this is to pursue the simplification of individual statements and call it “program optimization” to save several machine cycles. Then he started cheering and jumping for joy! And this may have buried considerable hidden dangers in the program. In fact, the so-called “program optimization” personally believes that the most important thing is-the optimization of the algorithm! It is the soul of the program, and the program language is just its carrier. The biggest reason why I use C is that it is efficient and can save the processing of a lot of details in the assembly Ethiopians Escort can put its research and development focus entirely on the algorithm, coupled with the software layering approach, so Ethiopia Sugar DaddyAt least for me, no matter 51, ARM or any other MCU, it is nothing more than establishing an interface to the MCU and building a minimum software architecture. The underlying algorithm can be used directly without modification. Of course, Needing to change a language and re-encode Ethiopia Sugar Daddy is naturally a “transplantation”, after all, its “soul” remains unchanged.
So back to the bottom, the so-called “no pain, no gain”, the majority of engineers, many of them study continuously all day long, while the majority of workers who give birth to children mechanically repeat the same labor all day long, which one is more important? Which one is weak? I feel:
The lower the technical content, the higher its replaceability, and the higher the replaceability, the lower its natural importance! Understand the situation and the faces of countless small bosses——
You can’t just get out, there are many workers inside
The higher the technical content, the lower its replaceability, and the more difficult it is to hand over the shift, and the correspondingThe higher the salary and benefits, the higher their importance.
Many bosses always have to consider the “fairness” among employees and always like to make “everyone happy”, such as the cup company… A few days after I left, they gave everyone a 10% salary increase , and some people boasted to me… saying that I shouldn’t leave, that I would be at a huge loss, etc…Ethiopians Sugardaddy. On the contrary, I feel that he is very unfortunate and admire their ability to survive in difficult situations…
The so-called “there is no honor or distinction in personal work, and it is impossible to be the best in everything”. Otherwise, why is there a difference in income? The higher the salary, the more it can illustrate the importance of talents. Let me quote one last point:
Salary is not important at the beginning, it is important to learn something
This view is also the motto of many small bosses. In fact, in order to reduce employment costs, they want to find cheap “labor force” with independent research and development capabilities. “That’s all… Then after 1 to 2 years, the newcomers’ comrades became stiff and jumped out. They shouted and cursed at his power, which made him faint… He didn’t understand either. ET EscortsFind the reason from yourself! It is indeed common to work overtime for free, and even when you go home, you will not continue to arrange responsibilitiesEthiopia SugarEthiopians Escort, treats women as men and men as animals! ! ! The remuneration given has been unfortunately low and there has been no salary increase. They also feed hollow glutinous rice balls to employees every day: “Now our company has become stronger ET EscortsET Escorts, you are the veterans, we will give you rooms and cars”… As a result, the company has become really powerful, and these are the first people to be lost. There are many examples…
And the starting salary Companies with high salaries often have complete welfare systems. The higher the salary, the greater the responsibilities. The things you learn will naturally increase exponentially compared to before, so you will naturally work harder, want to make more contributions to the company, and ultimately make progress. Benign reincarnation is a win-win situationpotential.
Of course, when it comes to “money paths”, politics comes first, economics comes second, and technology comes third. Only by dealing with people can you really make big money. Knowing these but not developing in this direction is mainly because of hobby. , I believe that many people who have carried out the technology to the end are also in this situation…
It’s too late… I remembered something when I went to bed. I will make up for it today… Health is very important. If you seek medical advice before the age of 30, you will be sick at the age of 30. I’m looking for you when I get sick. If I don’t want to open a special drawer to store medicine, I just insist on going to bed early and getting up early… Good night everyone.
