What does the F A do in the electronics factory?

Of course, the electronics factory is a factory that mainly installs circuit boards, and the general electronics factory basically says, 5 days and 8 hours, or 6 days and 8 hours, and overtime is hourly or hourly. However, when you actually come in, you have to have 2 days off a month, and that's a blessing. The surrounding environment of the electronics factory is also relatively poor, it is a moderately polluting enterprise, and the work of women is more detailed, and they do light work, but it is difficult to say about men.

Most of them are dry handlers, that is, porters. The electronics factory basically includes food and housing. At the end of the year, it is a few days off for the New Year, and the others are basically working or in the factory.

There's no leisure time for you to walk around. If you don't work overtime, you will be deducted from your accommodation and meals, and you will be estimated to get less than 700 yuan a month. In general, female workers are better than male workers.

If you go in as a general worker, you will have to suffer for at least 3 to 5 years, and the factory will consider changing you to a better position, if you can't stick to it within 3 to 5 years, you will wait to fire the squid. However, there are also people who do not pay attention to their health, and when they come back from their part-time jobs, work in an electronics factory, and get sick from pollution, so that future claims are far away. You must pay attention to your health in the electronics factory, otherwise, you will exchange your future life, that is, your lifespan, for the thousands of dollars that seem to be not heavy in the electronics factory today.

Therefore, for the inability to enter the electronics factory? It's better to make your own decisions. Social security and medical insurance are generally considered for you only after you have worked for more than 1 year.

However, if you are dismissed, you will either have to pay for social security and health insurance yourself, or you will be discharged. Not very cost-effective. Those who enter the electronics factory are basically from the intermediary, introducing junior high school students or high school and technical secondary school students in the society, because they are anxious to find a job, after paying an intermediary fee of several hundred yuan, they are hired to the electronics factory as general workers.

They are poorly prepared for themselves. After working in the factory for a few years, when I went home to get married and work, I had a physical illness. Working in an electronics factory, especially a general worker on the front line, will have more physical injuries.

It's not an external injury, it's an internal injury, basically a contaminated lesion of the internal organs. And when I found out, it was a few years or more than ten years later, and very few people could hardly succeed in making a claim. Only I think I'm unlucky.

College students and undergraduates rarely enter the front line of the workshop, because many of them know that the damage to the body in the electronics factory is a chronic poison. To put it bluntly, it is to put the most polluted work in the electronics factory to those secondary school students, high school students and even junior high school students, they are young, they know that they want to pay the thousand dollars, and when they are sick and go home, the electronics factory can continue to recruit operators from the intermediary, because in China, there is no shortage of people. If you don't do it, someone else will do it.

There are a lot of people. But these people don't even think that they are gambling with their health.

Factory automation.

In our company, FA is mainly responsible for equipment data communication, server maintenance, etc. But there's more to the FA than that.

Electronic factory cutting oil is a kind of industrial liquid used in the process of metal cutting, cutting and grinding, used to cool and lubricate tools and processed parts, cutting fluid is made of a variety of super functional additives through scientific composite compatibility, and has good cooling performance, lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy dilution characteristics. It overcomes the problems of traditional soap-based emulsion that it is easy to smell in summer, difficult to dilute in winter, and has poor anti-rust effect, and has no adverse effect on lathe paint, and is suitable for cutting and grinding of ferrous metals, which is the most advanced grinding product at present. The cutting fluid is better than the saponified oil, it has the characteristics of good cooling, cleaning, rust prevention, etc., and has the characteristics of non-toxic, tasteless, no erosion of the human body, no corrosion of equipment, and no pollution to the environment.

The materials placed in the warehouse are placed in alphabetical order in English, so that they can be stored and shipped out of the warehouse (for example, area A is a diode, area B is a crystal oscillator or N, W, shelves are placed electronic chips in a constant temperature room, etc.) And most of the materials are also combined with English and numbers to form a simple name (for example, if you want to take an x54679 material, you don't know x, take the wrong one to hit the board, or send it out, that's not the end.) So, remembering letters is the most basic.

QA in the electronics factory generally does the following work:

1) Certification and improvement of relevant systems (ISO, GMP, CMMI, etc., different nature of enterprise requirements are different).

2) Be in charge of technical measures and technology, quality and safety disclosure.

3) General quality work.

4) Quality training.

5) Management, analysis and testing of products. The company's R&D progress, the formulation of standards in the early stage of product development and the later R&D of products all require the participation of QA, so the following work must be completed:

1.According to the internal requirements of engineering data, organize laboratory tests on relevant items of products in a timely manner.

2.Develop a quality plan.

3.Review the inspection standards of various materials and finished products.

4.Handle customer complaints and returns in a timely manner to ensure customer satisfaction.

5.Preside over weekly quality meetings and promote the quality improvement of relevant departments throughout the company.

6.Count and analyze each quality meeting, and promote the quality improvement of relevant departments of the company.

7.Collect statistics and analyze the defective quality of each stage, and promote the improvement of each department to achieve the goal.

8.Analyze and improve the poor material counseling.

9.Keep quality records for traceability.

10.Audit and evaluate the quotient, and make corresponding records.

11.Evaluate the performance of subordinates.

Newton's second law f = ma, where f denotes the resultant external force experienced by the object, m denotes the mass of the object, and a denotes the acceleration of the object. This theorem is a representation of Newton's second law at low velocities.

Newton's second law in collegiate physics is expressed in the form of f=dp dt, which is in differential form, where p=mv denotes the momentum of the object, which can be placed in front of the differential sign because at low velocity, m, is almost constant, and dv dt=a; It has become Newton's second law in high school and junior high school.

Newton's laws of motion include Newton's first law of motion, Newton's second law of motion, and Newton's third law of motion, which were summarized by Isaac Newton in his book Principia Mathematica of Natural Philosophy in 1687.

Among them, the first law states the meaning of force: force is what changes the state of motion of an object; The second law states the effect of force: force causes an object to gain acceleration; The third law reveals the nature of force: force is an interaction between objects.

The laws in Newton's laws of motion are independent of each other, and their internal logic is self-consistent. Its scope of application is the range of classical mechanics, and the applicable conditions are particles, inertial reference frames, and macroscopic and low-speed motion problems. Newton's laws of motion explain the complete system of Newtonian mechanics and the basic laws of motion in classical mechanics, which are widely used in various fields.

f = the resultant external force on the object.

m = mass of the object.

a = acceleration of the object The acceleration of the object is directly proportional to the resultant external force experienced and inversely proportional to the mass of the object. The direction of acceleration is the same as that of the resultant force.

Wave soldering, foot cutting machine, assembly line, exhaust fan, placement machine, and various fixtures are used for testing. Ultrasonic pressure machine, aging equipment.

a(a)=10 f(f)=15

Hexadecimal is a representation of data in a computer. The hexadecimal system still uses position notation, and the bit weight is a power of 16.

In order to distinguish the numbers represented by different number systems, the number system is usually represented by additional subscript numbers or letters in the right parentheses, decimal numbers are represented by d, binary are represented by b, hexadecimal numbers are represented by h, and octal numbers are represented by o.

In hexadecimal: a(a)=10 b(b)=11 c(c)=12 d(d)=13 e(e)=14 f(f)=15

a-f corresponds to 10-15

Binary to hexadecimal is from back to front, every 4 binary numbers are converted into the corresponding decimal number as a whole, and the corresponding hexadecimal number can be found according to this number, and the first insufficient bit is filled with 0

For example, 111011

The last 4 bits of 1011 correspond to 10 base system 11, and the hexadecimal system corresponding to 11 in front of b is less than 4 digits, and 0 is added from the front, that is, 0011, corresponding to 10 base system 3, and 3 corresponding to hexadecimal system is 3

So this binary number converted to a hexadecimal number is 3b

a-f stands for 11-15 in decimal (i.e., the numbers we usually count).

To convert binary to hexadecimal, simply separate the binary digits from right to left by one unit per four digits, and use the four-digit binary number to represent a hexadecimal. The conversion table is as follows, with hexadecimal in parentheses.

0110 （6） 0111 （7） 1000 （8） 1001 （9） 1010（a） 1011 （b）

1100 （c） 1101 （d） 1110 （e） 1111 （f）

For example, 10101011 is divided into 1010 1011 and ab according to the hexadecimal conversion table

a=10， b=11, c=12, d=13, e=14, f=15。

From right to left, in groups of four, read as hexadecimal. (Actually, inside the computer they are the same).

What do the v, a, f, on the multimeter mean? The old electrician taught you, a little bit thoroughly.

The v, a, and f in the multimeter are all used to measure: voltage, current, and capacitance.

Specifically: voltage measurement.

Including: V AC voltage, V - AC voltage.

Measure the current. Including: a AC current a—DC current: capacitance measurement.

A current v voltage f may be capacitance.

A-grade means it's good to add a little bit, you think about what it means.

If you score 100 points in the paper, A is 90 points or above.
