And the fact is that, when we notice that a computer part failsthe first thing we think of is change it or, if you can afford it, directly, buy a new computer. The reality is that, in some cases, neither one nor the other is necessary. take it to a technician for a reballing.saving you considerable money. 

And yes, this is where we explain what we are talking about. 

What is Reballing?

Many of the elements that make up the hardware of a computer, especially in laptops, are soldered together through a small balls made of a tin alloy. This welding process is known as 'Ball Gray Array‘ (BGA) and consists of joining very specific areas to join components together, using these small balls as anchors.

With the passage of time, the incidence of heat and other elements, Some of these welds may lose their grip.causing the aforementioned failures and many more. And this is where reballing', which is basically the process of changing and replacing the tin balls that are in poor condition, replacing them with new ones that will bring your computer back to life. A 're-soldering', if you'll pardon the pun. 

Obviously, this process requires the hand of a professional but, as complicated as it may seem, the reality is that it is always going to be cheaper than buying a new motherboardThe new computer, other components or, of course, a new computer. 

We say that reballing requires a professional's hand, because it is not a matter of just melting more tin balls to the parts and that's it. Far from it. The reballing process involves, first of all, removing the old welds. and then, remove the affected components, clean them, check them, andonce it has been restored to its natural state, put them back in place correctly and start soldering. It is not a simple process to do at home, although everyone is free to do what they want with their computer. 

However, it is important to know that the reballing device is not exactly cheap. and doing it with a machine that is not suitable for the job can be fatal for the computer. It is not worth it, as it is a fairly affordable repair and the results will last for years.

By the way, a distinction should be made between reballing and reflow.The two techniques, which appear to be similar, but which can give very different results. Reflow, unlike reballing, applies an appropriate amount of heat to the old solder joints so that they make the connections they should again. The problem with this technique is that too much heat can end up damaging components and ultimately lead to a much more expensive repair.

What is Reballing?

Electronic components prone to heat failure

The electronic components using BGA chipsas processorsmemory or disks, are prone to failures due to a tin alloy which cracks under prolonged heat. This can lead to problems such as disconnection of chips and boards.

What is the Reballing process?

The Reballing is a repair technique for electronic components. in which tin alloy solder is replaced and re-soldered at specific points. This process can only be performed by professionals with a specialised machine called a '...'.Rework Systems‘.

What problems can Reballing solve?

The aim of reballing is to repair components that have started to fail and to avoid the purchase of expensive new parts. This technique can be especially useful for solve problems related to the soldering of BGA chips in notebooks, graphic cardsIt can also be applied to the repair of consoles, consoles, mobile phones and other devices that suffer from high thermal wear and tear. It can also be applied to the repair of PS3 with yellow lightamong other hardware problems.

  • Common causes of failure in soldering of electronic components:

    Among the most common causes of soldering failure are lack of temperature, poor soldering quality and lack of maintenance of the equipment. In addition, temperature changes during the use of the component can generate vibrations that affect its soldering.
  • Alternatives to reballing:

    Sometimes it may be more convenient to purchase new components to avoid potential problems in the future, although this can be more costly.

It is important to note that Reballing is not the same as reflowing.The use of the same type of equipment is similar in some devices. In addition, due to the ban on the use of lead in soldering, it is necessary to use special techniques to avoid chip and board disconnection problems. In general, the Reballing is very useful for repairing components and avoiding unnecessary costs for the purchase of new parts.

However, it is important to bear in mind that this is a complex process which must be carried out by specialists in a controlled environment and with appropriate tools.

Reballing process step by step

Preparation of the necessary equipment and materials

Before starting the process, it is necessary to have the necessary tools and materials to carry it out correctly:

  • Rework station or hot air soldering station
  • Fluxfor a good resolution and cleanliness of the plate
  • New welding balls to fit the size of the PCB spheres
  • Metal spatula to remove the chip after solder release
  • Isopropyl alcohol o contact cleaner for PCB cleaning
  • Antistatic gloves to avoid damaging electronic components

Removal of the damaged chip

The first thing to do in the reballing process is to remove the damaged chip. To do this, heat must be applied to the solder spheres that hold it to the PCB by using a hot air soldering station. Remember to apply heat carefully so as not to damage the other surrounding components. Once sufficient heat has been applied, remove the chip from the motherboard using a metal spatula, taking care not to damage the other side of the spheres on the PCB.

Cleaning of the motherboard

After removing the chip, it is important to clean the PCB board so that no solder residue remains and it is easier to re-solder in the future. It is recommended to use isopropyl alcohol or contact cleaner and a plastic spatula to avoid scratching the board.

Fitting of new balls and welding

Once the plate has been cleaned, it is place the solder balls on each solder point of the PCB using a stencil. It is important that the balls are the right size for each soldering point. The chip is then placed on the solder balls and fixed with a little flux.

Finally, the next step is to soldering the PCB using the soldering station by hot air, heat must be applied to the plate until the solder balls melt and form a strong connection.

Replace the chip

After the welding process, we proceed to return the chip to its original position and check that all connections are correctly soldered and secured. It is advisable to make a visual check of the circuit to ensure that there are no flux or solder residues that could cause problems in the future.

When is reballing worthwhile versus buying a new component?

Advantages and disadvantages of Reballing

The main advantage of Reballing is the possibility to repair an expensive component at a more affordable price compared to buying a completely new component. In addition, reballing can maintain the integrity of the equipment, preventing data loss and downtime.

Among the disadvantages of reballingis the need for specialised equipment and trained professionals to perform the process. Furthermore, although reballing can be satisfactory, it is not always a guarantee that the original problem will not recur in the future.

Common causes of electronic component soldering failure

Failure of welds can occur for a variety of reasons, including the exposure to high temperatures, shocks and vibrations. In electronic components using BGA chips, which are particularly prone to heat failure, the alloy that binds them together cracks over time, which can lead to equipment failure.

Alternatives to Reballing

While Reballing may be a viable option for the repair of electronic componentsThere are other methods that can solve similar problems. These include:

  • Reflow: technique to simply apply heat to the board in order to repair a damaged solder.
  • Change of components: in some cases, it is possible that the component where the damaged weld is located cannot be repaired, in which case replacing the complete part would be an alternative.
  • Purchase of new components: sometimes the purchase of new components can be a more efficient and economical alternative to the reballing process.

The Reballing is a technique that can be applied to laptops and graphics cards. where BGA chips are the most susceptible to solder failure due to heat build-up.

The most common problems are overheating and chip disconnection. These problems can be solved by reballing. To carry out the process, specialised tools and specific knowledge of electronics are required.

It is important to note that, although the Reballing is a good repair optionis not always the most effective and cost-efficient, as it may sometimes be better to opt for component replacement.

Reballing on consoles, mobiles and other devices

Consoles, mobile phones and other devices that use BGA chips can also be repair by the Reballin processg. Heavy use of the devices causes electronic components to be exposed to high temperatures, increasing the likelihood of solder failure.

Through reballing, you can repair integrated circuit soldering faults and extend the service life of the devices. It is important to note that the reballing process is not only applicable to electronic components in poor condition, but can also be used to prevent future failures.

Reballing RAM and other peripherals

For RAM and other peripherals, reballing can be an effective and cost-efficient solution to repair solder failures. Failing electronic peripherals can manifest situations such as data read/write problems or crashes.

On the other hand, the repair of electronic peripherals also applies to computer equipment. In this respect, the Reballing work can be effective in troubleshooting component failures not only in laptops, consoles and mobiles, but also in servers, desktops and other devices.

  • In short, reballing is an effective technique for re-soldering electronic components with unstable solder joints.
  • For each electronic device and component, the reballing process has specific characteristics and the intervention of a specific professional is necessary.
  • Reballing is not always the best option, in some cases it is possible to replace the affected component.
  • In any case, the reballing process can save money and extend the lifetime of devices, especially in times of crisis like the current year.

How to detect failures in soldering of electronic components?

Most common symptoms of welding failure

One of the most common symptoms of welding failure is the overheating of the electronic component. Electronic devices may become warm during normal use, but if they become warmer than usual, it may be an indication of a defective welding.

Another common symptom is when the device intermittently or suddenly shuts down during use for no apparent reason. In addition, the appearance on the screen of streaks, dots or other strange patterns that appear and disappear may indicate soldering failures.

What to do if a welding fault is detected?

If a soldering fault is detected on an electronic component, it is best to take it to an authorised professional specialised in the reballing process. A soldering failure can cause irreparable damage to the electronic component if not remedied in time.

The practitioner will examine the component to determine the degree of damage to the weld and, if necessary, apply the Reballing technology to solve the problem. If this is not possible repair the componentIt is recommended to replace it with a new one. In case you want to detect soldering faults yourself, you need specific tools and knowledge to carry out the detection process. It is important to be careful to avoid damaging the component or the electronic board.
