With graphic card reball, you can repair and renew graphics card and other computer chips without spending a lot of money.
– What is Ribal?
Reballing literally means putting balls again, and in computer repair, it is called replacing tin balls of different chips. You must have seen the page of different computer chips. On these plates, there is an orderly row of tin balls to make the necessary electrical connections. This layer of tin plays a vital role in how the electronic part of the device works. For some reason, you may need to replace these tin connections that are ball-shaped on the plates. In this case, the machine part will not work properly and the tin balls will have to be replaced. This action is called chip reballing.
– Reasons for graphics card ribal
Tin balls of chips may be damaged for various reasons. In this case, the performance of the part will be problematic. The device may freeze during operation. Failure to maintain continuous communication can be one of the complications of damage to tin balls of chips. In this situation, the part can be repaired with the ribal method. In general, the reasons for chip ball damage should be looked for in the following cases:
Heat Damage: Tin balls can be damaged if the chip is overheated for an extended period of time. For this reason, the graphics card is more prone to problems with tin balls and the need for ribbing than other components.
Damage caused by impact: The connection of the tin layer may have been disconnected due to impact on the device. The tin layer must be properly mounted on the chip pins to make the connection.
Cracking and wear: The creation of small cracks in tin balls can be caused by wear and tear of the part and long-term use. In this case, the piece is repaired by ribbing.
– How to do graphics chip ribal
Carrying out the ribal method has various technical points that the computer repairman must be familiar with when repairing and replacing tin balls. If you don’t have experience in this field, don’t do it yourself and leave computer repair to professional people. Because ribbing requires experience and special equipment. Otherwise, irreparable damage will be done to the chip.
In general, reballing involves heating balls of tin so that they are removed from the chip.
Then the surface of the chip should be cleaned.
Finally, the new tin balls must be carefully fitted to the chip pattern.
But this work is very detailed and includes various technical instructions. In the following, we explain the graphics chip rebalancing process further
– Separation of tin balls
To start, you need to remove the chip from the motherboard. For this reason, the piece should be heated with an industrial hair dryer.
Be careful not to heat the piece directly. For this reason, the chip is covered with a protective layer or shield.
After removing the chip, the tins should be loosened with a heating device.
For this, experience in working with the heater is very important. The temperature used and the duration of heating the piece must be determined by an expert.
Often the piece is exposed to heat for a minute or two to melt the tin bases. Of course, the temperature of the heater must also be set correctly.
Hoya is also used for this purpose. The repairman melts the tin bases with a tip.
The important thing is not to overheat the chip.
Finally, after the tin layer melts, the balls are separated from the chip.
– Part cleaning
Immediately after removing the tin balls, the surface of the part must be cleaned. This is done with 90% alcohol. You can use a cotton pad dipped in alcohol.
If tin residue remains on the chip, the surface of the chip is cleaned using solder.
During the work, the surface of the chip is covered with solder paste several times. Solder paste helps make electrical connections. Using too much solder paste or flexi liquid will cause the tin balls to stick and not connect to the chip.
– Placing tin balls on the chip
The final step is to place the new tin balls on the chip. But this stage itself has different steps.
First of all, the size of tin balls should be chosen correctly. There are different tin balls for ribal action. If the size of the balls is not careful, the correct result will not be obtained.
Then the part should be placed in the fixture. With this device, the part is fixed and allows the repairman to perform the delicate process of placing tin balls on it.
A good amount of solder paste should be placed on the chip so that the balls stick together.
After the part is fixed, tin balls should be placed on the chip using a stencil. The template should be used according to the technical information of the chip. A stencil is a metal sheet that has a pattern of balls in it. This type of repairman can put the balls in their right place.
Then the tin balls are placed on the template. The balls are placed on the chip by passing through the holes of the template. The important thing is that all the holes in the template are filled with balls.
After this, the holder should be gently opened to remove the chip base from the device. Care should be taken not to change the location of the balls.
Then, with an industrial hair dryer, the connection of the balls with the chip is completed. This part is also a sensitive operation. The base of the balls must be melted to stick to the chip with the help of solder paste.
