And to understand the market of computer accessories
3DMark is a professional hardware testing software, mainly used to test the graphics card. How come no one said anything about chip readers and oscilloscopes?
There are also a lot of capacitors, crystals, and other electronic parts
And that's a must! I do this line, the owner of the best to hire 2 employees even your own 3 people so better, equipment 1, 3 oscilloscopes 2, to have 6 multimeters digital 3 pointers 3 units. Troubleshooting card 3 pieces, disassembly tools screwdriver to complete (within the 6 angle should also be equipped), soldering iron 20W 30W 50W should be prepared solder thick and thin to be equipped with flux soldering extrusion, hot air gun, cooling fan a few computers 1-2 units of software to measure the graphics card that the 3dmark a top to have anti-virus software, needless to say, and other electronic components, these things and so on repair for a period of time in the large number of purchases there are a lot to say that finished I suggest that you have the intention to open a store to learn a PC, switch, network cable & network clamp & crystal head, screwdriver and other tools to remove hardware. Multimeter, multifunction socket, soldering iron, rosin, solder, adapter card, motherboard diagnostic card, fan, power supply, a variety of drivers
Basic multimeter, soldering iron, brush, industrial alcohol, eraser, silicone grease, solder, rosin, you can find the test wave instrument, patch machine and so on
Think I'm going to go to repair the machine to bring a piece of test card, manuals, magnets, ten flower screwdriver, eraser, my tools burner, the disk, the tape, and so on. I'm going to take a test card, a manual, a magnet, a screwdriver, an eraser, my tools, a burner disk, alcohol. I think the general take these will be enough to use ~~~~ general home computer will not be used to have to soldering iron in order to repair the share ~ ~ ~ (most of the time!) The first is technology: only good technology you can stand firm in this industry, can have better development,
The second is the market: choose the right market to do business.
Suppliers should be good to find, but be careful not to just consider the cost, and do not pay attention to their quality, quality first principle to find suppliers, in the business to pay attention to is the interpersonal relationship, the interpersonal relationship, back to you to bring a lot of good out of the.
Hardware repair what you need
1. tools, the minimum tools to have: desoldering tools, measuring tools, etc. Also have the skills to use the tools. But also have the skills to use the tools;
2. basic knowledge, at least the knowledge of electronics, the motherboard components and the role of knowledge to have;
3. various pins on the board should be mastered by the number of pins, the key pins must find a way to remember.
4. information, collect information is very important, but to learn should understand how to collect information, how to use the Internet to search;
(Beginners should have an actual normal motherboard and the motherboard corresponding to the complete information: manuals, datasheets on the board of the various chips, datasheets of the CPU, the value of the various test points, etc.). There are many kinds of motherboards, it is unrealistic to collect all of them, but it is possible to collect all the information of a common motherboard)
5. Collect some bad boards for practice; it is better to collect a few boards that are the same or close to your good boards, which will be very helpful for your study.
With the above preparation, you are ready to start learning. Be careful not to break the good board that you use as a reference, and do whatever you want with the rest.
It seems to be important to add one more thing: newbies have to learn to be self-reliant or they will never be able to solve problems on their own. Since you'll have to be independent sooner or later, make sure you force yourself to learn this one.
The idioms cite one or one to rule them all both illustrate the importance of figuring one out.
Please add and revise anything that is incomplete.

Specifically to prepare, should be based on the amount of business to determine the amount of business, you can be equipped with more good tools, the amount of business is not large enough, you can use the existing tools, and strive to solve the problem, really can not be solved, can be handed over to us to solve.
How much do your circuit board repair kits cost? I want.
The kit uses a high-precision needle bed, data acquisition system and high-performance computer software system with the use of the needle bed and other detection equipment is more expensive, the software system debugging workload is greater (takes two to three days), and therefore the kit is currently only adapted to high-volume repair business. The kit is customized, according to the complexity of the circuit board test degree, the average cost of 1-10 million yuan per set. Information about the kits is often asked for, but to reiterate, if your business is small, the kits are not suitable.
I want to start a hard disk repair business, do I have to buy a PC3000?
Not necessarily, we have a set of PC3000, because it is more expensive, most of our trainees here did not buy PC3000, have to use PC3000 to repair the hard disk, the trainees often ship the hard disk to our company, and then send it back after repairing it, to maximize the resource **** enjoyment, to reduce the burden of trainees.
I am repairing motherboards and monitors, is it necessary to use a thermostatic anti-static soldering iron?
Our company's maintenance engineers have more than a dozen, most of them use ordinary anti-static soldering iron, only to repair the notebook of the master with a thermostatic anti-static soldering iron, for there is no need to use a thermostatic anti-static soldering iron, benevolent, wise, very different views. With this problem, I also looked through a lot of books and materials. Contrary to our habits, the information is almost unanimous that there is a need to use a thermostatic iron, the main reason is that the temperature of the thermostatic iron to control the temperature is good, will not burn the chip. Another reason is that constant temperature anti-static iron can be anti-static, can prevent static electricity damage to the chip. Is this really the case? With this doubt we made an experiment (2002 experiment), with an ordinary anti-static iron to replace a good monitor and a normal work on the motherboard resistance, capacitance, inductance, field effect tube, line tube, integrated block, were operated ten times. As a result, we found that the motherboard and the display can still work properly. The anti-static soldering iron for the experiment is a 30W worth 10 yuan yuan of the most common electric anti-static soldering iron. Since then I have decided that in terms of performance, the ordinary anti-static iron is not much worse than the thermostatic anti-static iron.
What's a better model for a 10,000 meter?
There are many kinds of multimeter brand models, some dozens of dollars, some hundreds of dollars, repair motherboards, hard drives, laptops, etc. General use of digital multimeter, repair monitors and other analog circuits generally use mechanical meter. I use my own digital multimeter is 40 yuan 9205, the mechanical table of low-grade forty dollars is enough, some have shockproof function of high-grade mechanical table needs hundreds of dollars.
What does the 850 soldering station look like?
We are now using the welding station are generally Gaudi or Parker 850, with 220V AC power, maximum power 270W, the air pump is a diaphragm type, the airflow is 0.2-242m/min, infinitely variable, the pump's power of 45W, the heat generator for the 250W resistor wire, the heat can be infinitely adjustable between 100-420 degrees. Comes with four air nozzles. 240 yuan each, the air pump warranty of one year, the heating core is not warranty. In fact, there are many brands of 850 soldering station, of which the Japanese white light 850 is more expensive, the quality is also better.
What kind of programmer is better?
Programmer has a variety of brands and models, from the price point that the cheap only 200 yuan, the expensive need for seven or eight thousand dollars, the difference is mainly in the ability to write the chip model, there are many chips low-grade programmer brush can not be, while the high-grade programmer is the size of the programmers to eat. If only for motherboard maintenance, about 1000 yuan is more appropriate. The programmer we use is RF-1800, 1000 yuan.
Do I need an oscilloscope for the repair? How much does it cost?
Oscilloscope is one of the commonly used maintenance tools, mainly used to test the waveform signal of the device, divided into digital oscilloscope, analog oscilloscope, and virtual oscilloscope. One of the virtual oscilloscope is a combination of computer software and electronic hardware products, the current genuine price is not cheap. The most important parameter of the oscilloscope is the frequency, used for motherboards, laptops and other maintenance work of the oscilloscope is currently required about 200M, the minimum can not be lower than 100M. there are some friends with 20M or 40M of the old oscilloscope plus a frequency meter can be used to make up a little bit, but the effect is poorer. 200M of the new oscilloscope needs 6000-30000 yuan. Now some of our students buy used oscilloscopes, 100M or 200M used oscilloscopes are cheaper, according to the brand, color, frequency and other factors, the price ranges from 500-3000 yuan. In addition, we have found after statistics that 60% of the repair technicians of computers and related equipment do not use oscilloscopes, while 99% of the cell phone repair technicians use oscilloscopes. The difference in this number is mainly due to the fact that a large percentage of computers and related products can be repaired even without an oscilloscope. So if you're strapped for cash, you can buy an oscilloscope without rushing.
What's the deal with playing the resistance card?
The resistor card is used for the repair of accessories with standard connectors, which can be used to play the resistance value and measure the signal. The resistor card is designed and processed by us according to the maintenance needs. Now the electronic market in the small and medium-sized maintenance department to repair the success rate of the motherboard is generally not more than 60%, mainly because they only repair some of the easier to solve the problem, for the bus failure they generally do not repair. After-sales service department of the manufacturer's repair success rate is generally more than 98%, which requires them to repair even if the bus is out of order, it is necessary to use the resistive value of the card. There are two kinds of playing resistance value card, one is manual, the other is automatic, manual playing resistance value card is very simple, it is clearly labeled with the address, data, control bus, maintenance as long as the signal directly with an oscilloscope or multimeter to measure the relevant points on the signal to improve work efficiency, eliminating the need to look through the information of the trouble. Automatic playing resistance card in the manual playing resistance card on the basis of an increase in the digital-to-analog converter, data acquisition circuit, interface circuit and software system, so that you can deal with the relevant data signals through the computer, the efficiency can be improved a lot of automatic playing resistance card has a data acquisition function, that is, we can often say that the "learning" function, which can be a good motherboard signal acquisition to the computer, the motherboard's signal acquisition. It can be a good motherboard signal acquisition to the computer as a database of records saved up, the maintenance can be faulty motherboard data can also be collected for comparison, so as to find out the failure point. A set of automatic resistance cards costs 3,000 yuan, and manual resistance cards cost 350 yuan each.
Can you introduce the stencil stencil and BGA chip placement machine?
Ever heard of the Mayan civilization? Some of the Mayan buildings even with the current advanced technology is difficult to build up, but thousands of years ago the Mayans did, when the level of productivity and technology with the current incomparable, it can be considered that some of the skills were mastered by the Mayans, and we do not recognize it. Our BGA welding machine can also be considered similar to the Mayan civilization. The machine is mainly used for manual replacement of BGA package chips, complimentary full set of related tools, such as heating furnace, planting ball template, tin ball, solder paste, etc., you can replace all the motherboards, graphics cards, notebooks, etc., BGA package chips, soldering a chip only 20-30 minutes, the success rate of an average of more than 90%. Equipment structure is simple, high reliability, maintenance costs are very low, especially the heating furnace is converted from an ordinary electric furnace, damage to the self can be repaired, which is compared with some manufacturers of professional equipment, the advantage is very obvious.BGA chip mounting machine has always been regarded as the pride of the Oriental Repair Network, we use the simplest tools to solve the most difficult problems. Machine full set of external price of 1400 yuan, students 50% discount.
What does PCB break wire repair adhesive do?
PCB broken line repair adhesive is actually a conductive adhesive, commonly used to repair the notebook keyboard conductive film. In addition, in the processing of circuit boards, such as large areas of broken wires in the case, you can also use the glue repair.
What kind of test card should I buy?
At present, the commonly used test card can be divided into two kinds, one is the ordinary test card, the other is a single-step test card, the ordinary test card generally spend 20-40 yuan can buy, some similar test card cost 70-100 yuan, in fact, there is no essential difference between the use. Single-step test card is a professional test card, generally at least ten code tube above, it can be locked in a single step of the CPU working state, the importance of its significance lies in the repair of bus failures, through the code tube of hexadecimal and binary conversion, to determine which bus in the end is a problem. Single-step test card is more expensive, 3800 yuan each.
What is a BGA chip test holder for?
As the name suggests, it is used to test the BGA chip is good or bad, the principle of the test is to replace the method, as you can see from the picture above, the test seat of the frame is a lot of holes in the insulating plate, the diameter of the holes is 0.7MM, the spacing is 1.27MM, is drilled with high-precision CNC drilling machine, the error of no more than 0.05MM. holes are installed inside the diameter of the needle 0.5MM, the needle of 0.3MM diameter. In the center is a spring of 0.3MM diameter, and at both ends is a sharp needle of 0.3MM diameter. The assembly precision of the test holder is very high, and the positioning and installation skills to the motherboard are only mastered by a very few technicians of Oriental Repair Network. If you have hundreds or more BGA chips do not know is good or bad, you can take over to us to help you test, the success rate of more than 99%, test a chip takes 1 minute, of course, you can also buy the test seat back to self-testing. 400 pins below the test seat of 3,000 yuan each, 500 pins more than the test seat of 5,000 yuan each.
Is it necessary to make an ultra-clean space to carry out hard disk repair business? If so, how much does it cost?
For many repair technicians, hard disk open repair is a mysterious out-of-reach thing. The reason for this is that many books related to hard drives have described that hard drives can only be opened for repair in a class 100 ultra-clean space, which is very expensive to produce.
We consulted a number of companies specializing in air purification, their quotes from tens of thousands to hundreds of thousands of dollars, the simplest less than 100 level of ultra-clean bench has to be more than 10,000 dollars, for most of the strength of the maintenance business is not strong enough to be willing to invest in this way, and therefore they have not made too much of a payoff in this area, resulting in hard disk open repair is still a mystery! The first is to make sure that you have a good idea of what you are doing.
Is this really the case? With this doubt, in 1999, we began the research in this area, at first, the project is not sure, do not want to take too much risk, so we found the Yadu company, spent thousands of dollars to rent their ultra-clean room for a month, the use of this one month's time, we made a lot of experiments to solve some of the hard disk disk failure, including the replacement of the head chip, the replacement of the head assembly and the head of the deadlock, and accumulated a lot of raw materials. We have accumulated a lot of raw data. One of the most exciting thing is that we found that the cleanliness of the hard disk to the air is not as high as written in the book, in the usual cleaner room hard disk can be in the case of opening the disk body to work continuously for more than ten days without any problem, this conclusion for many hard disk repair technicians is very significant, they can not have to invest a lot of money on the hard disk to open the maintenance of the business.
What tools do professional computer repairers have?
1 a recovery CD-ROM with boot I think that software errors in computers are a relatively common problem. In the era of using windows 98 system crash is also common, it does not move to give you a face. Therefore, the recovery CD-ROM is essential. Commonly speaking, the recovery CD is the GHOST backup file carved in the CD (of course, you can use other software software backup, but the most commonly used is GHOST). If you often repair computers for other people, you can go to the computer saving business to ask for a copy of the recovery CD (for them it is the installation disk is right, otherwise how can they install dozens of machines a day?) The CD-ROMs are not for installers, they are for installers. This is because they have CDs for most of the computers they make. If you're just looking out for yourself, then it's better to have it customized. There are many advantages of using CD-ROM as a boot disk. Disks are easy to be damaged, but if you use CD-ROM properly, it will last longer than your computer; CD-ROM has high speed and high capacity that disk does not have. So if conditions permit, try to use the CD-ROM as a startup disk. 2 data cable - you must not underestimate the two kinds of data cables in the computer, which is extraordinarily easy to neglect the place. Data cable after a long time plugging and unplugging, often lead to can not find the drive, transfer data error, can not read and write and other faults. This kind of failure is easy for others to find the problem in the drive, it is difficult to think that just this small data cable is at fault. Encountering similar failures, before replacing the drive, you may want to try the trick of changing the cable, which may allow you to reduce a lot of unnecessary trouble.
3 Screwdrivers and pliers
While screwless cases are all the rage these days, a screwdriver is still an essential tool. One is usually enough, preferably with a magnet and the kind with a long handle, which will make it a lot easier for you. At the same time, the screwdriver has another good use, and listen to the author slowly. When you meet a piece of the motherboard without instructions, will be connected to the POWER, RESET button trouble (POWER, RESET is the most basic computer buttons, the other just some lights, there is no impact are not big). According to my experience, the chassis panel wiring logo will be printed on the motherboard, but the motherboard may not be clearly identified, may be ineffective to connect the jumper according to the logo, or even a motherboard POWER button has two ways to connect (so far I have not been able to figure out the reason for the prawns for guidance). Anyway, you connected to the line found invalid, the screwdriver at this time is very useful ah. You can use a screwdriver at the same time to touch the two motherboard jumper at the metal pin, so a pair of pairs to try, until the computer starts, then these two are connected to the POWER jumper. Using the same method, you can find where the RESET button is connected after the computer boots up. The sharp-nosed pliers' are for pulling and inserting the jumper caps. With thick fingers on the motherboard to pull the jumper cap is never an easy thing, some motherboards also because of the design problem is also particularly difficult to pull. With a sharp-tongued pliers that can be half the battle.
4 software in the windows 98 boot disk, there are some simple commands, barely make do, to really do, with some professional efficiency will be higher. The first of course, I would like to recommend DM, it is a disk management tool, not big, but quite powerful. Partitioning, formatting speed is quite fast. It can also backup partition tables, repair zero-tracks, and allow old motherboards to support high-capacity hard drives. To remind you, you must use the universal version, otherwise it may only be able to operate on its own hard disk, does not recognize other brands of hard disk. Then introduce a hard disk tool, partitionmagic partition magician. It is characterized by the operation of the hard disk, will not destroy the data, just not fast enough. This software can run under DOS, and is a graphical interface, the operation is very convenient. You can change the partition size at will, convert partition format, hide partition, bad partition test and other functions. (Tip: Whether it is DM Universal Edition or Partition Magic, you need to have a certain level of practical operation, it is best to use the hard disk brand recommended by the hard disk tools) These things are also very convenient to carry around, the software a CD-ROM will be enough, with all of the above, has been able to solve a lot of problems. If you want to be more "professional" a little bit, with the following: ISA graphics card - specifically to deal with brush bad BIOS motherboard. When upgrading the BIOS fails, only an ISA graphics card can bring your computer back to life. Although the operation can be restored in the dark, but if you can see, who wants to go blind? DEBUG error detection card - sometimes, not rely on experience can be inferred where the fault, so we should take up the weapons of science to fight it. Using a DEBUG card will make detection faster and easier. It is also a good helper for overclocking, you can use it to detect which parts are not able to keep up with overclocking, and then prescribe the right "medicine". Detection method you read the manual I believe you will understand, I will not say more here. I computer first aid tools on these, software can also be based on the need to increase or decrease their own, after all, the capacity of the CD-ROM is still quite large. I hope that this article can be useful to everyone, there are questions that I would be happy to discuss with you.
