Various types of screwdrivers, screwdrivers, ammeters, air guns, welding pens, monitors and other test equipment, installed software (including GHOST system) and computer accessories that can be sold, as well as brushes, (dust removal) and fault diagnosis cards (ISA interface and PCI interface are integrated). Especially in the process of maintenance, more boards should be prepared for troubleshooting. As for the software, it is necessary to prepare more system installation CDs and various drivers.

Software: antivirus, hardware inspection, hard disk inspection and repair, common system drivers and application software.

Instruments: diagnostic cards, electronic tools (multimeter, soldering iron, etc. ) test bench, etc. Spare parts and common tools.

Need common antivirus software, system disk (maintenance technology universal pre-installed system 4.0), hardware detection software, 3dmark200 1, common listening to music, watching movies, chatting tools, etc.

You also need motherboard detection cards, DVD engravers, welding tools, and circuit detection tools, such as screwdrivers and brushes. ...

There is also the need to understand the market of computer accessories.

3DMark is a professional hardware testing software, which is mainly used to test graphics cards. Why didn't anyone say anything about chip readers and oscilloscopes?

There are also a large number of capacitors, crystal oscillators and other electronic parts.

It is also necessary! That's what I do. The landlord had better hire two employees, even the three of you. The equipment is 1, three oscilloscopes, six multimeter digits, three pointers, three fault diagnosis cards, a screwdriver for disassembly tool (including the inner hexagon) and an electric soldering iron 20W 30W 50W, all of which should be matched with solder thickness to help welding. Hot air gun, cooling fan, several computers, 1-2 sets of software, that 3dmark needs anti-virus software, and needless to say, the rest are all electronic components, which need to be repaired for a period of time and bought in large quantities. There are still many things to say. It is suggested that if you are interested in opening a shop, learn a PC, a switch, a network cable & a net clip & a crystal head, a screwdriver and other hardware tools. Multimeter, multifunctional socket, soldering iron, rosin, solder, adapter card, motherboard diagnostic card, fan, power supply, various drivers.

Basic multimeter, soldering iron, brush, industrial alcohol, eraser, silicone grease, solder, rosin, you can find a wave meter, mounter and the like.

Ask me to repair the machine, bring a test card, instructions, a magnet screwdriver, an eraser, my tool burning disc and alcohol. I think these are generally enough ~ ~ ~ Most household computers don't need an electric soldering iron to repair ~ ~ ~ (Most of the time! The first is technology: only with good technology can we gain a firm foothold in this industry and have better development.

The second is the market: only by choosing the right market can we do business.

Suppliers should be easy to find, but be careful not to consider only the cost and not the quality. The principle of quality first is to find suppliers. What you should pay attention to in business is interpersonal relationship. Good interpersonal relationships will bring you many good results.

What is needed for hardware maintenance?

1。 Tools, the least tools are: welding tools, measuring tools, etc. Also have the skills to use tools;

2。 Basic knowledge, minimum electronic knowledge, knowledge of motherboard components and functions;

3。 The number of pins on the board should be mastered, and the key pins must be remembered.

4。 Information, collecting information is very important, but to learn, you should know how to collect information and how to use online search;

Beginners should have an actual normal motherboard and complete information corresponding to the motherboard: instructions, data sheets of chips on the board, data sheets of cpu, values of test points, etc. There are many kinds of motherboards, and it is unrealistic to collect all of them completely, but it is possible to collect all the information of an ordinary motherboard.

5。 Collect some bad board exercises; It's best to collect a few boards that are the same as or close to your good ones, which will be of great help to your study.

With the above preparations, you can start learning. Be careful not to break the good board for reference, and the rest will be handled by you.

It seems to be added that novices should learn to stand on their own feet, otherwise they will never be able to solve problems independently. Because you will be independent sooner or later, you must force yourself to learn this rule.

Both idioms "draw inferences from one instance" or "know everything" illustrate the importance of understanding one.

There is something incomplete, please add and modify it.

Motherboard maintenance tools: soldering iron (required, 15 yuan), multimeter (required, 40 yuan), hot air soldering station (required, 200 yuan), programmer (required, 300- 1500 yuan), test card (required, 40 yuan), oscilloscope (optional, second-hand 6544). ...

What software should I bring as a computer maintenance master? 98/ME 2K/XP and a set of system installation disks in 2003 (a set of GHOST would be better), its patches and a 3.5 startup disk. If possible, you can get a USB optical drive with a universal drive disk. If you want to be professional, you should also bring some common software such as OFFICE 2K/2003. If the maintenance user is a family, it is recommended to bring some latest versions of QQ and MSN. Finally, the most important thing is the anti-virus software disk ~ it is best to have more than five kinds of anti-virus software disks around, suitable for all kinds of people.

Other tools: a screwdriver and ten screwdrivers (you can buy a toolbox if necessary)

Hardware maintenance engineers should also have "hardware test cards"

If the conditions are superior, it is best to have a notebook and a mobile hard disk.

If you want to build a network, you should bring a network cable tester, network cable pliers, dial pliers, spare network cable and a pack of crystal heads. Now with the 98-XP system disk chost disk main detection card antivirus screwdriver, there is no need for screws. If the hardware is broken now, it will be replaced, so the maintenance is reasonable.

Upstairs is very comprehensive. I'm a computer maintenance master, and I have everything you said. Of course, if it can't be repaired, I need to move his case to the company for a comprehensive overhaul. If possible, it is necessary to equip a welding gun (hot air gun), an electric soldering iron, a bios programmer, a magnifying glass and a diagnostic card.

According to years of maintenance experience, we believe that the higher the maintenance tools, the better, and the more expensive they are, the easier they are to use. Mainly depends on whether they are suitable for themselves. Among the tool items listed above, those marked "(essential)" must be available, and the rest are optional, which will be more efficient. Whether to prepare or not depends on the business volume. If the business volume is large, you can equip yourself with some useful tools. If the business volume is not large enough, you can use the existing tools to try to solve the problem. If you can't solve it, you can give it to us.

What is the price of your circuit board repair kit? I want it.

The kit uses high-precision needle bed, data acquisition system and high-performance computer software system. Due to the high price of testing equipment such as needle bed and the heavy workload of software system debugging (it takes two to three days), this suite is only suitable for large-scale maintenance business at present. These toolkits are customized. According to the complexity of the circuit board, the average cost of each kit is 1-65438+ ten thousand yuan. Information about suites is often asked. Again, if your business volume is small, you should not share a suite.

I want to carry out hard disk maintenance business. Do I need to buy a PC3000?

Not necessarily. We have a set of PC3000, because it is more expensive. Most students here don't buy PC3000, so they have to use PC3000 to repair the hard disk. Students often send hard disks to our company, and then send them back after being repaired, so as to maximize the enjoyment of resources and reduce the burden on students.

I repair motherboards and monitors. Is it necessary to use a constant temperature anti-static soldering iron?

Our company has more than a dozen maintenance engineers. Most of them use ordinary anti-static soldering irons, and only the master who repairs notebooks uses constant temperature anti-static soldering irons. People have different views on whether it is necessary to use a constant temperature anti-static soldering iron. With this question, I also read a lot of books and periodicals. Contrary to our habit, the almost unanimous opinion in the data is that we must use a constant temperature anti-static soldering iron. The main reason is that the temperature of the constant temperature anti-static soldering iron is well controlled and will not burn the chip. Another reason is that the constant temperature anti-static soldering iron can prevent static electricity from damaging the chip. Is that really the case? With this problem in mind, we did an experiment (in 2002), in which the resistors, capacitors, inductors, field effect tubes, exhaust tubes and integrated blocks on a completely good monitor and a normal motherboard were replaced by an ordinary anti-static soldering iron, which was operated for ten times respectively. As a result, we found that the motherboard and monitor can still work normally. The anti-static soldering iron used in the experiment is the most common electric anti-static soldering iron, and its value is 10 RMB. From then on, I decided that the performance of ordinary anti-static soldering iron was not much worse than that of constant temperature anti-static soldering iron.

What model is better for ten thousand watches?

There are many brands and models of multimeters, some tens of dollars, some hundreds of dollars. Digital multimeters are generally used to repair motherboards, hard disks, notebooks, etc. Mechanical watches are generally used to repair analog circuits such as monitors. My own digital multimeter is 40 yuan's 9205. Forty yuan is enough for low-grade mechanical watches, and some high-grade mechanical watches with shock-proof function need several hundred yuan.

What is the 850 welding platform like?

The welding table we are using now is generally Gaudi or Ber 850, which uses 220V alternating current, the maximum power is 270W W W, the air pump is diaphragm type, and the air volume is 0.2-242m/min, which is infinitely adjustable. The power of water pump is 45W, the heating element is 250W W, and the hot air can be adjusted infinitely between 100-420 degrees. Comes with four vents. 240 yuan each, air pump warranty for one year, heating core warranty. In fact, there are many brands of 850 welding platform, among which Japanese white light 850 is more expensive and the quality is better.

What kind of programmer is better?

There are many brand models of programmers, from the price point of view, the cheap one is only 200 yuan, and the expensive one is 7,000 yuan or 8,000 yuan. The difference is mainly in the chip model that can be written. There are many chips that low-level programmers can't brush, and high-level programmers can take various sizes. If it is only used for mainboard maintenance, 1000 yuan is more appropriate. The programmers we use are RF- 1800 and 1000 RMB.

Do you need an oscilloscope for maintenance? How much will it cost?

Oscilloscope is one of the commonly used maintenance tools, which is mainly used to test the waveform signal of equipment. Divided into digital oscilloscope, analog oscilloscope and virtual oscilloscope. Among them, the virtual oscilloscope is the product of the combination of computer software and electronic hardware, and the current genuine price is not cheap. The most important parameter of oscilloscope is frequency. At present, the oscilloscope used for mainboard and notebook maintenance needs about 200M, and the minimum should not be less than1000 m. Some friends can make do with an old oscilloscope of 20M or 40M plus a frequency meter, but the effect is a bit poor. A 200M new oscilloscope costs 6000-30000 yuan. Now some of our students buy used oscilloscopes. 100M or 200M second-hand oscilloscopes are relatively cheap, ranging from 500-3000 yuan depending on the brand, color and frequency. In addition, through statistics, we found that 60% of computer and related equipment maintenance technicians do not use oscilloscopes, while 99% of mobile phone maintenance technicians use oscilloscopes. The difference in this figure is mainly due to the fact that a large proportion of computers and related products can be repaired even without oscilloscopes. So if you are short of money, you don't have to rush to buy an oscilloscope.

What's with the resistance card?

Resistance card is used to repair accessories with standard connectors, and can be used for resistance and signal measurement. The jam is designed and processed by ourselves according to the maintenance needs. At present, the success rate of small and medium-sized maintenance departments in the electronic market is generally less than 60%, mainly because they only fix some problems that are easy to solve, and generally do not repair bus faults. The maintenance success rate of the after-sales service department of the manufacturer is generally above 98%, which requires them to repair the bus even if there is a problem. At this time, the resistance card will be used. There are two kinds of resistance cards, one is manual and the other is automatic. The manual resistance card is very simple, and the address, data and control bus are clearly marked on it. During maintenance, it is only necessary to measure the signals of relevant points directly with oscilloscope or multimeter, which improves the work efficiency and saves the trouble of looking up data. On the basis of manual resistance card, automatic resistance card adds digital-to-analog converter, data acquisition circuit, interface circuit and software system, so that relevant data signals can be processed by computer, and the efficiency can be improved a lot. Automatic card blocking has the function of data acquisition, that is, we can often call it "learning" function, which can collect the signal of a good motherboard into a computer as a record of a database, and then collect the relevant data of a faulty motherboard for comparison during maintenance, so as to find out the fault point. A set of automatic resistance cards is 3000 yuan, and a set of manual resistance cards is 350 yuan.

Can you introduce stencil steel mesh and BGA mounter?

Ever heard of Mayan civilization? Some Mayan buildings are difficult to build even with the current advanced technology, but they did it thousands of years ago. The productivity and technical level at that time were not the same as now. It can be thought that some skills were mastered by the Mayans, but we didn't realize it. Our BGA welder can also be regarded as something similar to Mayan civilization. This machine is mainly used for manual replacement of BGA packaging chips, and presents a complete set of related tools, such as heating furnace, ball planting template, solder balls, solder paste, etc. It can replace all BGA packaging chips such as motherboards, graphics cards and notebooks. It only takes 20-30 minutes to weld a chip, and the average success rate is over 90%. The equipment has simple structure, high reliability and low maintenance cost. In particular, the heating furnace is modified from ordinary electric furnace, which can be repaired by itself after being damaged. This has obvious advantages compared with the professional equipment produced by some manufacturers. BGA mounter has always been regarded as the pride of Oriental Maintenance Network, and we have solved the most difficult problems with the simplest tools. The external selling price of the whole machine is 1400 yuan, with 50% discount for students.

What is the use of PCB broken wire repair glue?

PCB broken wire repair adhesive is actually a kind of conductive adhesive, which is often used to repair the conductive film of notebook keyboard. In addition, the adhesive can also be used to repair large-area broken wires when processing circuit boards.

What kind of test card should I buy?

At present, there are two kinds of commonly used test cards, one is ordinary test card and the other is single-step test card. Ordinary test cards can be bought at 20-40 yuan, and some similar test cards cost 70- 100 yuan, but there is no essential difference in use. One-step test card is a kind of professional test card, which generally has at least ten code tubes. It can lock the CPU in a single-step working state, and its important significance lies in repairing bus faults. Through the conversion of hexadecimal and binary code tubes, it is used to judge which bus is out of order. The one-step test card is more expensive, 3800 yuan each.

What is the BGA chip test bench for?

As the name implies, it is used to test the quality of BGA chips. The principle of testing is to use substitution method. As can be seen from the above figure, the frame of the test-bed is an insulating plate with many holes, the diameter of which is 0.7MM and the spacing is1.27 mm. The hole is drilled by a high-precision CNC drilling machine with an error of less than 0.05 mm. The hole is equipped with a needle with a diameter of 0.5MM, a spring with a diameter of 0.3MM in the middle and sharp needles with a diameter of 0.3MM at both ends. The assembly accuracy of the test bench is very high, and the positioning and installation skills on the motherboard are only mastered by a few technicians of Dongfang Maintenance Network. If you have hundreds or more BGA chips, you can bring them and we will test them for you. The success rate is over 99%, and it takes 1 minute to test a chip. Of course, you can also buy a test bench to test yourself. A test stand with less than 400 stitches is 3000 yuan, and a test stand with more than 500 stitches is 5000 yuan.

Is it necessary to do ultra-clean space for hard disk maintenance? If so, how much will it cost?

For many maintenance technicians, hard disk open maintenance is a mysterious and unreachable thing. The reason why this happens is that many books related to hard disks are introduced. Hard disks can only be opened and repaired in 100 ultra-clean space, and the production cost of ultra-clean space is very high.

We have consulted many companies specializing in air purification, and their quotations range from tens of thousands to hundreds of thousands. The simplest clean workbench, less than 100, costs more than 10 thousand. For most maintenance companies with insufficient strength, they are unwilling to invest in this area, so they have not made too many attempts in this area, which makes hard disk open maintenance still a mysterious topic.

Is that really the case? With this problem, we started the research in this field in 1999. At first, we were not sure about this project, and we didn't want to take too much risks, so we found Du Ya Company and spent thousands of dollars to rent their clean room for a month. Using this month's time, we have done a lot of experiments and solved some hard disk failures, including the replacement of head chip, head assembly and head deadlock. What excites us most is that we find that the cleanliness of the hard disk to the air is not as high as that written in the book. In a clean room, open the disk and the hard disk can work continuously for ten days without any problems. This conclusion is of great significance to many hard disk maintenance technicians, who can start hard disk maintenance business without investing a lot of money.

What tools do professional computer maintenance personnel have?

1 recovery CD with boot. The author thinks that software errors in computers are a common problem. In the era of using windows 98, system crashes are also common, and it always gives you a bad look. Therefore, it is very important to restore the CD. In layman's terms, the recovery CD is a GHOST backup file engraved on the CD (of course, it can also be backed up by other software, but the most commonly used one is GHOST). If you often repair other people's computers, you can go to the computer storage company and ask for a recovery CD (for them, that is the installation disk, otherwise how can you install dozens of them a day? )。 Because the CD of computer storage company is suitable for most computers. If you just "think" for yourself, it is certainly better to tailor it. There are many advantages to using CD as a startup disk. Disks are easily damaged. If the CD is used properly, it will last longer than your computer. Optical disk has high speed and high capacity that magnetic disk does not have. So try to use CD as a startup disk if possible. 2 data lines-you must not underestimate two kinds of data lines in the computer, which are particularly easy to be ignored. Long-term plugging and unplugging of the data cable often leads to that the drive cannot be found, the transmitted data is incorrect, and it is impossible to read and write. This kind of fault is easy for others to find the problem on the drive, and it is hard to think that it is just this small data cable. In case of a similar fault, try to change the cable before replacing the drive, which may save you a lot of unnecessary trouble.

3 screwdriver and needle-nosed pliers

Although the screwless chassis is popular now, the screwdriver is still an indispensable tool. Generally speaking, one hand is enough, preferably magnetic, and a long handle will make you more convenient. At the same time, the screwdriver has another wonderful use, and listen to the author slowly. When you encounter a motherboard without instructions, you will be worried about connecting the power supply and the reset button (power supply and reset are the most basic buttons of the computer, and the others are just indicator lights, with little difference). According to the author's experience, the wiring logo on the chassis panel will be printed on the motherboard, but the logo on the motherboard may not be clear, and it may be invalid to connect the jumper according to the logo. There are even two ways to connect the power key of a motherboard (I haven't figured out the reason yet, please advise). Anyway, when you connect the wire and find it ineffective, the screwdriver will be of great use at this time. You can use a screwdriver to touch the metal pins at the jumpers of two motherboards at the same time, so try one by one until the computer starts, and then the two jumpers are connected to the power supply. Similarly, you can find the connection location of the reset button after the computer starts. Needle-nosed pliers are used to pull out and insert jumper caps. It is not easy to pull out the jumper cap on the motherboard with thick fingers. Some motherboards are particularly difficult to pull out because of design problems. With needle-nosed pliers, you can get twice the result with half the effort.

4 software in the windows 98 startup disk, there are some simple commands, which are barely acceptable. If you really do it, it will be more efficient to use some professionals. First of all, I would like to recommend DM. This is a disk management tool, small in size, but quite powerful. Partitioning and formatting are quite fast. You can also back up the partition table, repair zero tracks, and at the same time, you can let the old motherboard support large-capacity hard disks. Remind you, you must choose the universal version, otherwise you may only be able to operate on your own hard disk, and you will not be able to identify other brands of hard disks. Introduce another hard disk tool, partitionmagic partition magic. Its characteristic is that when operating the hard disk, it will not destroy the data inside, but the speed is not fast enough. This software can run under DOS and has a graphical interface, which is very convenient to operate. You can change the partition size at will, convert the partition format, hide the partition, test the bad partition and other functions. (Bian Xiao tip: Both DM Universal Edition and Partition Magic need a certain level of practical operation. It is best to use hard disk tools recommended by various hard disk brands. ) these things are also very convenient to carry around, and a CD of software is enough. With the above, many problems have been solved. If you want to be more "professional", use the following: ISA graphics card-the motherboard dedicated to handling BIOS. When the BIOS upgrade fails, only ISA graphics card can make your computer "glow again". Although the operation can be resumed in the dark, who wants to be blind if they can see? DEBUG debug card-sometimes, we can guess the fault without experience, so we should take up scientific weapons to fight it. Using debug card will make detection faster and easier. It is also a good helper for overclocking, which can be used to detect which accessories can't keep up after overclocking, and then prescribe the right medicine. I believe you will understand the detection method after reading the operation manual, so I won't say much here. The author's computer first aid tools are all in this respect, and the software can be increased or decreased as needed. After all, the capacity of CD is still quite large. I hope this article is useful to you, and I will be happy to discuss it with you if you have any questions.
